چکیده
Thin-walled structures are widely used in anti-collision devices for various vehicles due to their light weight and high energy absorption. Offset collision is a common scene traffic accidents. Because the commonly thin-walled do not consider this complex method, absorption effect of structure cannot meet requirements. In paper, C-shaped frame composed steel tubes proposed. The configuration studied through theoretical analysis numerical simulation, it found that can absorb stably offset collision. experiment simulation were carried out, crashworthiness was investigated verify accuracy feasibility method. A large-scale parameter influence characteristics configuration, different materials sections investigated. Based on above test results, an optimal design method improving considering collisions This paper provide technical support related research integrated anti-climbing energy-absorbing parts rail trains under

Evaluation of Passenger Rail Vehicle Crashworthiness
In recent years there has been an increased effort to investigate and improve the crashworthiness of passenger rail vehicles in the United States. The structural crashworthiness requirements for new rail vehicles are changing to include specifications for crash energy management and crush zones rather than primarily specifications of vehicle and component strengths. In addition, the structural ...
متن کاملParameter-based topology optimization for crashworthiness structures
Abstract Topology optimization methods like the homogenization method are very efficient for statically and dynamically loaded structures, but the use of these methods for the topology optimization of crashworthiness structures runs into a lot of problems. Especially in structural contact problems, the optimization functions are not smooth and the use of local sensitivity information is not suc...

With the advent of powerful computers, vehicle safety issues have recently been addressed using computational methods of vehicle crashworthiness, resulting in reductions in cost and time for new vehicle development. Vehicle design demands multidisciplinary optimization coupled with a computational crashworthiness analysis. However, simulation-based optimization generates deterministic optimum d...
متن کاملCrashworthiness Analysis and Energy Absorption Enhancement of a Passenger Rail Vehicle
Interests in increasing the trains’ speed of travel, generated higher degrees of wariness about the possible sever accidents. Since, the passenger wagon car body needs to be a safe compartment for its occupants therefore; great attention should be paid on its design. In this study, a passenger car body that is originally made in Eastern Germany and its chassis are modeled to simulat...
متن کاملImproved Vehicle Crashworthiness via Shape Optimization
Advancements in high-performance computing and in nonlinear dynamic structural simulation have made it possible to virtually test potential designs prior to building and testing expensive prototypes. These tools alone, however, still require an engineer to develop a design based on intuition and numerous time-consuming and error-prone iterations. The next level of advancement is software to aut...
