NUMERICAL PREDICTION OF VARIOUS FAILURE MODES IN SPOTWELDED STEEL MATERIAL

  • Wichita State University - Sachin Patil

Published 2018-06-22 by SAE International in United States
Crash simulation is targeted mainly carried out by the collision regulations FMVSS simulation to identify problems in vehicle structures. A modern car structure consist of several thousand weld-type connections, and failure in these connections plays an important role for the crashworthiness of the vehicle. Therefore accurate modeling of these connections is important for the automotive industry in order to improve Vehicle collision characteristics. In pursuit of this key requirement, we introduced a proper methodology for the development detailed weld model to study structural response of the weld when the applied load range is beyond the yield strength. Three-dimensional finite element (FE) models of spot welded joints are developed using the LS-Dyna FE code. In this process the force estimation model of spot welds is explained. The results from this paper shows good agreement between the simulations and the tests. Therefore, spot weld model obtained from this study should be considered for applications in crash analysis.

Geometric variation stemming from manufacturing can be a limiting factor for the quality and reliability of products. Therefore, manufacturing assessments are increasingly being performed during the early stages of product development. In the aerospace industry, products are complex engineering systems, the development of which require multidisciplinary expertise. In such contexts, there are significant barriers against assessing the effects of geometric variation on the functionality of products. To overcome these barriers, this paper introduces a new methodology consisting of a modelling approach linked to a multidisciplinary simulation environment. The modelling approach is based on the parametric point method, which allows point-scanned data to be transferred to parameterised CAD models. In a case study, the methodology is implemented in an industrial setting. The capability of the methodology is demonstrated through a few applications, in which the effects of geometric variation on the aerodynamic, thermal, and structural performance of a load-bearing turbofan component are analysed. The proposed methodology overcomes many of the current barriers, making it more feasible to assess the effects of geometric variation during the early…

Analysis of Single-Vehicle Accidents in Japan Involving Elderly Drivers

  • National Traffic Safety & Enviro Lab. - Kazumoto Morita, Michiaki Sekine

  • 2018-01-9752
Published 2018-05-11 by SAE International in United States
The Japanese population is aging rapidly, raising the number of traffic accidents involving elderly drivers. In Japan, single-vehicle accidents are a serious problem because they often result in fatalities. We analyzed these accidents by vehicle type, age group, and driving area, and found that many of them occurred when young or elderly people were driving light motor vehicles (K-type vehicles) in non-urban areas. We analyzed the characteristics of single-vehicle accidents. On the assumption that the number of rear-end collisions is a proxy for the traffic volume, we used the number of such collisions to control for driving frequency. It was found that in single-vehicle accidents, elderly drivers were at higher risk than other age groups, especially when driving K-type vehicles in non-urban areas. A possible explanation is the higher frequency with which the elderly drive K-type vehicles in areas where there are few other vehicles on the road.

Abdominal Injury Patterns in Frontal Crashes: Analysis of Front and Rear Seat Occupants using NASS/CDS and CIREN

  • Virginia Tech - Meghan K Howes

  • 2018-01-9751
Published 2018-05-11 by SAE International in United States
Field accident data from the National Automotive Sampling System/Crashworthiness Data System (NASS/CDS) and the Crash Injury Research and Engineering Network (CIREN) databases were used to identify the factors affecting abdominal injury type and incidence for front and rear seat occupants in frontal collisions. The NASS/CDS analysis was conducted to identify the nature and magnitude of abdominal injuries, while a separate CIREN analysis was conducted to investigate the mechanistic differences between types of abdominal organ injuries. Abdominal injury risk was found to increase with increasing occupant age in both the front and rear seating positions. Abdominal injury risk also increased with factors associated with more severe collisions including the number of crash events, extent of frontal crush, collision type, and crash speed. Seatbelt use reduced the overall risk of sustaining abdominal injuries, with unbelted occupants overrepresented in terms of abdominal injury risk in both the front and rear seats. Abdominal injury type was associated with occupant seating position and restraint use. For front seat occupants, the solid abdominal organs such as the liver and the spleen…

A 3D CFD underhood thermal simulations are performed in two different vehicle platooning configurations; (i) single-lane and (ii) two-lane traffic conditions. The vehicle platooning consists of two identical vehicles, i.e. leading and trailing vehicle. In this work, heat exchangers are modeled by two different heat rejection rate models. In the first model, a constant heat rejection rates are considered as similar to no-traffic vehicle condition. In the other model, a varied heat rejection rates are implemented by considering an aerodynamic influence on fuel consumption rates. In a constant heat rejection rate model, the trailing vehicle thermal performance is significantly dropped in single-lane traffic due to reduced oncoming cold mass air flow velocities from leading vehicle. Also, the similar observations are found in two-lane traffic but at higher vehicle separation distances. In a varied heat rejection rate model, significant drop in temperature raise is observed in both leading and trailing vehicles when compared to a constant heat rejection rate model in the single-lane and the two-lane traffic conditions. In leading and trailing vehicles, the varied heat…

Published 2018-04-13 by SAE International in United States
This paper deals with the analysis of cooling airflow for two different front-end designs of a heavy truck. The first design is a cab-over-engine (COE) cab; the second is a Soft Nose (SN) cab, which in this case is basically an elongation of the grille area of the COE cab to obtain a smoother shape of the cab. The SN model used in this investigation was extended 200mm from the COE front. Computational Fluid Dynamics (CFD) was used as the tool for examining the aerodynamic properties of the vehicle models. The configurations were evaluated both with inactive and active heat exchangers, in order to examine the effect of heating the air on the drag co-efficient and also to determine the cooling capacity of the different models. A sub- study was performed where different opening percentages of the grille area was investigated to determine the minimum percentage opening that would be needed to achieve a radiator Top Tank Temperature (TTT) value below a target limit of 100°C. The results show that there was potential for drag…

A novel ICE ON/OFF control strategy for hybrid electric bus based on route information

Abstract: ICE ON/OFF control strategy is critical for fuel economy in the hybrid electric vehicle (HEV). The fuel cumsumption cut off at ICE is at OFF state when the vehicle stops especially at vehicle jams. It significantly profits for more fuel saving. Motor-only drive mode is rarely used in real-time control because of the power system meet the uncertain driver demand. Battery state of charge (SOC) balance also affects ICE ON/OFF control decision. ICE ON/OFF state optimization is still a critical problem that is rarely effectively resolved. Minimum Principle was used in real-time control and has a global optimization in many papers. However, there is no paper to apply this algorithm in ICE ON/OFF control optimization. This paper introduces a novel control method using Minimum Principle to select an appropriate ICE state, which extracts rules from the optimal results applied to real-time control based on predicted route information. Experiments prove proposed route-based control significantly improves the fuel economy. Compare to the conventional control strategy, route- based control has 18.0% fuel cut, very close to DP-based…

  • 2018-01-9176
Published 2018-04-13 by SAE International in United States
Windshield deicing performance is a key metric for HVAC system development and optimization within the sphere of commercial vehicle design. The primary physical properties that drive this metric are pressure drops in the HVAC ducting, flow rate of the air through the system, and the transient warm up curve of the HVAC unit. However, many design engineers also have to take underhood packaging into consideration while trying to optimize a new HVAC system design. This study leverages historical deicing simulation methodologies in conjunction with modern computational horsepower so as to optimize the HVAC ductwork in the studied commercial truck at the front end of the design process. By iterating on a design in the computational domain under steady-state and transient flow and thermal conditions, a robust HVAC system design can be created even prior to the prototyping stage of development. Furthermore, when the vehicle runs through an experimental regime, the design engineer has reasonable certainty of meeting their targets with respect to the HVAC system’s deicing performance. By completing steady state cold flow and transient…
