Development of Parametrically Integrated Software Platform for Passenger Car Brake System2019-01-12314/2/2019
The hydraulic servo brake system for passenger car plays a central role in occupant protection, which directly affects the automotive active safety and road handling. In this paper, an integrated parameterized software platform of hydraulic servo brake systems is proposed to realize fast and efficient braking system development. At first, according to the structure and working principle of the hydraulic servo brake system, the relationship among amount of fluid required for brake caliper, pedal feel and performance of the brake system is analyzed. Then, based on kinematics and dynamics of the hydraulic servo brake system, a simulation model for analyze pedal feel and amount of fluid required for brake caliper is built in AMESim, which is composed of brake pedal, vacuum booster, brake master cylinder, brake hoses and brake calipers, etc. In addition, the accuracy of the simulation model is verified by bench tests, and the significantly influential factors on the amount of fluid required for brake calipers are analyzed through orthogonal experimental design. The ranking of their influence is diameter of brake wheel cylinder D first, piston ring stiffness K second, and followed by gap δ. Finally, the “ECE” regulation and enterprise standards are used to evaluate the design of the automotive brake system, and an optimization solution is proposed based on evaluation results. With a friendly visual interface and integration technology, the design of the hydraulic servo brake system can be quickly implemented on this software platform, including component characteristics, brake performance calculations, simulation analysis, and regulatory determination. This research can be used as an important reference for obtaining the optimal braking performance of passenger cars, and also provides a theoretical basis for design of brake-by-wire system.

Accelerated Testing of Brake Hoses for Durability Assessment2017-01-03893/28/2017
The durability performance of brake hoses is a crucial issue for such components. Accelerated fatigue testing of brake hoses is necessary for understanding achievable lifetime, actually computation of durability is quite cumbersome due to the many different materials the hoses are made from. Despite SAE standards are available, accelerated testing of brake hoses subject to actual torsional and bending stresses seem important to provide relevant feedback to designers. In this paper, an innovative methodology for assessing the fatigue behavior of brake hoses of road vehicles is proposed. A dynamic testbed is specifically designed and realized, able to reproduce the actual assembly conditions of the hoses fitted into a vehicle suspension. The designed testbed allows to replicate actual loading conditions on the brake hoses by simulating the vertical dynamics and steering of the suspension system together with brake pressure. A procedure to extract the relevant loading cycles for damage is proposed and applied. The tests performed by exploiting the new testbed are in good agreement with the reported lifetimes of actual brake hoses fitted into test vehicles.

Brake Flexible Dynamic Analysis Attached to McPherson Suspension, Optimizing the Input Parameters in IPS Cable Simulation2016-36-015710/25/2016
The high level of reliability of virtual analysis for suspension system development should not be thinking only for comfort and performance purpose, considering the `growing number of failures due to the touch between components in dynamic condition. The study establishes a simple and optimized methodology, able to predict more accurately the flexible brake hose path subject to the steering motion and associates with the independent suspension course, aiming the best route in order to achieve a low cost and robust design. In turn, the flexible brake hose non-linear model invalidates the multibody study to get the best route. However, with the aid of motion making use of NX9 [1] CAD [2] software was prepared dynamic movement that subjects front independent suspension system that establishes a Cartesian routine that maps 977 points, much higher than 9 points from previous studies, comprising a more accurate path performed by the hose. This data served as input to the IPS [3] software for the construction of flexible model to be simulated, were assigned mechanical and geometrical properties for each component. Finally, it was set to IPS software the dynamic suspension system routine, thus yielding the flexible brake hose behavior under certain circumstances, verifying the effectiveness of the component to the package requirements, avoiding undesired dynamic interference and early degradation of the flexible element.

A Study on Prediction of the Brake Hoses Deformation Associated with a Vehicle Motion2012-01-02244/16/2012
A Brake hose is a core part of the braking system that delivers the hydraulic pressure generated in the master cylinder to an actuator, which, in turns, creates braking force. The braking hose can be deformed in many different ways under various driving conditions, and it is essential that the brake hose should not experience any excessive deformation or interference with surrounding parts for durability and reliability. Despite of its importance, the brake hose design method has been very limited. Currently, it is tentatively designed with simple curves, such as a spline curve, then tested and modified with many different prototypes by doing a trial-and-error process due to the difficulty in simulating the behavior of the hose. This paper focuses on establishing the following processes to enhance the reliability of the drawing in the earlier stage of the vehicle development by a prompt and accurate simulation prediction; (1) Facilitating the design and modification of the hose path by developing a CAD template for the brake hose and fitting, (2) Coordinates of Body Fitting & Axle Fitting are extracted and calculated in order to create input data for a CAE software to perform a deformation analysis of brake hoses associated with the vehicle motion. The obtained CAE results are then converted into a CAD 3D model and used to check the interference with surrounding parts. The whole process is dedicated to two main objectives; the usability and reliability. Firstly, a unified GUI is developed to handle a data extraction, pre/post processing, 3D model generation, and interference check. Therefore, it allows even inexperienced engineers to easily get the analysis results and use it in the CAD environment. Secondly, by incorporating the beam cross-section model into the analysis, twist of a hose can be considered. The results are compared with the 3D scanning data of the hose installed in the actual vehicle for verification. The proposed processes and program can significantly decrease the computing time and increase the accuracy of the simulation for the presented example problems.

Selection of EPDM Elastomer in Brake Hose Application for Improved Brake System Performance2010-01-188510/5/2010
Brake system has been considered as the most important safety system for a vehicle. Performance of the Brake system depends upon various factors like purity of brake fluid, material and construction of rubber hose, rubber seal performance etc. The purity of the brake fluid is one of the most vital factor and incompatibility of the rubber hose with brake fluid causes contamination of the brake fluid. This intern can cause shrinkage / swelling of master, slave cylinder rubber seals. The change in the dimensional of the rubber seals directly affects the performance of the brake system. In order to evaluate the performance of the brake system, Styrene Butadiene Rubber (SBR) and EPDM elastomers with different % of ethylene and varying ENB content were considered for brake fluid compatibility test. These rubber materials were tested in the different brands of DOT 3 brake fluid. Design of experiments has been carried out on EPDM material with different % of ethylene and varying ENB content to find out suitable and optimized combination of the rubber and brake fluid brands. The selected combination from the experiments has been taken further for component level tests. Traditionally, methods of test for the compatibility of brake fluid with rubber hose may not address the actual vehicle service conditions. To addresses the actual conditions; a new methodology has been developed. Hoses were successfully tested and their performance was compared in terms of volumetric expansion of rubber seal, brake fluid contamination, brake pedal sinking, and pedal efforts. This methodology can also be extended to detect contaminations in other types of fluids used in the automobile.

Automotive Brake Hose Fluid Consumption Characteristics and Its Effects on Brake System Pedal Feel2010-01-00824/12/2010
During the automotive brake system design and development process, a large number of performance characteristics must be comprehended, assessed, and balanced against each other and, at times, competing performance objectives for the vehicle under development. One area in brake development that is critical to customer acceptance due to its impact on a vehicle's perceived quality is brake pedal feel. While a number of papers have focused on the specification, quantification and modeling of brake pedal feel and the various subsystem characteristics that affect it, few papers have focused specifically on brake corner hoses and their effect on pedal feel, in particular, during race-track conditions. Specifically, the effects of brake hose fluid consumption pedal travel and brake system response is not well comprehended during the brake development process. This paper introduces the basic construction of automotive brake hoses, the test methodologies and test results used to quantify brake hose fluid consumption under various operating conditions, and it illustrates the influence of hose performance at the vehicle-level using simple analyses on an example race track-capable sports car.
