Automobile frames, particularly trellis frame structures, are engineered for superior dynamic performance, with stiffness being a paramount consideration1. These frames frequently utilize welded tubes, a manufacturing process made more complex by the necessity of bending tubes to precise angles to meet packaging and assembly requirements2. This bending, however, induces residual stresses that can substantially compromise the frame's durability3. This investigation employs a detailed finite element simulation to analyse the structural deformation and residual stresses that arise during the bending of Cold Electric Welded (CEW) annealed round pipes4. A comprehensive 3D mechanical model, incorporating realistic tooling and contact interactions, was developed to accurately simulate shape change, ovality, and wall thickness redistribution during the bending process5. CEW pipes, unlike their Electric Resistance Welded (ERW) counterparts, possess minimal initial forming stresses, and the

In today's dynamic driving environments, reliable rear wiping functionality is essential for maintaining safe rearward visibility. This study sharing the next-generation rear wiper motor assembly that seamlessly integrates the washer nozzle, delivering improved performance alongside key benefits such as better Buzz, Squeak, and Rattle (BSR) characteristics, reduced system complexity, cost savings, and enhanced perceived quality. This integrated design simplifies the hose routing which improves the compactness and the efficiency of the design. This also enhances the spray coverage and minimizes the dry wiping unlike the traditional systems that position the washer nozzle separately. A non-return valve (NRV) is incorporated to eliminate spray delays ass it maintains consistent water flow giving cleaning effectiveness. Since this makes the nonfunctional parts completely leak proof due to the advanced sealing, it increases the durability and reliability in long run. As this proposal offers

Water leakage is a common issue in vehicles, especially during water testing. It often occurs due to a gap between the seal bulb and the closure panel. This gap can result from variations in flange angle, flange curvature, closure surface, or seal bulb height. This study focused on how flange curvature affects seal bulb height and sealing performance. A Computer-Aided Engineering (CAE) method was used, supported by tests on physical samples. Multiple simulations were done using different flange curvatures. Results showed that with a constant Side View Flange Angle (SVFA) of 150°, increasing the Flange Curvature Radius (RZX) reduced seal bulb deformation. The optimal flange curvature radius was found to be 250 mm, where the bulb compression was 1.2 mm. Sharp or tight flanges caused the bulb to deform more, reducing contact and sealing force. To reduce this deformation, a hollow tube was inserted inside the seal bulb. The hollow tube used had an internal diameter of 10 mm and an external

In this paper, a systematic and in-depth study is carried out on the key engineering problem of the accurate calculation of the flexural capacity of L-shaped concrete-filled steel tubular columns. Based on the basic framework of mechanics theory, the basic design principle of reinforced concrete members is integrated, and the nonlinear characteristics of steel and concrete materials in the process of stress are mainly considered, such as steel yield strengthening, concrete compression damage, etc., and the ultimate bending moment calculation model which is more suitable for the actual stress state is constructed. Through rigorous theoretical derivation and multi-parameter comparative analysis, the final formula for calculating the bearing capacity of special-shaped columns not only has clear mechanical concept support, but also systematically defines the scope of application of the calculation method. The verification results show that the established calculation method not only meets

Minimally invasive and interventional platforms increasingly demand smaller profiles, tighter tolerances, and components that maintain performance under thermal, chemical, and mechanical stress. Polyimide (PI) has emerged as a workhorse within these parameters because it combines high strength, thermal stability, chemical inertness, dielectric performance, and biocompatibility in thin-wall formats suitable for catheters, electrophysiology tools, and neurovascular systems. 1- 3

This paper focuses on defining the optimal length of rear axle brake lines (flexible polyamide tubes) for commercial vehicles by simulating the lines digitally by considering tube behavior and various axle articulation conditions. Currently, the length of rear axle brake lines are predominantly defined with the help of a physical mockup by articulating axle conditions in a vehicle. This approach requires actual components such as frame, axle, suspension, etc., which consumes considerable time and cost. Through technological advancements, prototyping can be reduced and convergence on digital to build can be achieved through digital simulation. This paper explores tube properties, axle configurations and definitions, and various methods of digitally simulating line articulation. Boundary conditions, space reservations and design criteria for pneumatic routing are defined for the type of line designed. Digital simulation of rear axle brake lines articulation was performed and compared

The possibility of reducing CO2 emissions through sustainable paraffinic fuels opens opportunities for the continued use of existing infrastructure and combustion systems. At the same time, fuel switching also presents challenges in terms of the materials used. The changing composition of paraffinic fuels and their impact on plastic materials is a frequent topic of discussion. Compared to distillate diesel, neat paraffinic fuels contain almost no aromatics, which are known to cause swelling in plastics, especially elastomers. This literature review aims to examine and summarize studies on the influence of paraffinic fuels compared to distillate diesel on elastomers. On the fuel side, attention will be given to fuels with different total aromatics content and neat paraffinic fuels. In the field of elastomers, materials used for sealing applications and hoses are analyzed in detail. Special attention will be paid to NBR, FKM, and EPDM. The review aims to answer three questions.

Medical tubing is an essential component of countless healthcare applications, from intravenous (IV) and oxygen lines to catheters and diagnostic equipment. These tubes, often made of clear flexible polymers, must be produced to exacting standards: free of contaminants, strong under pressure, and biocompatible. However, the joining process to connect these tubes can introduce significant manufacturing challenges.

This article presents a design of experiments (DOE) approach to analyze automobile engine coolant leakage from hose joints. The data includes force measurement at hose joints through physical validation and computer-aided engineering (CAE) simulation results. The proposed approach involves utilizing digital validation data, which simulates the entire experiment using CAE. The novelty of this approach lies in its reliance on digital validation data rather than conventional physical measurements, thus providing cost and time savings for the organization. In this study, the authors investigated the force at the coolant hose joint, which results in oil leakage as the response variable. Nine independent factors were evaluated in this experiment. The study concluded through the identification of critical parameters and opposed regression model to predict force at hose joints.

This document describes a method for determining the specific gravity of tubing, fabricated from polytetrafluoroethylene, after a controlled heating and cooling cycle. The specific gravity obtained by this method is a measure of relative molecular weight of the resin. The measure, termed relative specific gravity (RSG), increases with decreasing molecular weight (refer to Sperati and Starkweather, 1961).
