The Research On Crank-Slider-CST Low Rear Protective Device Of Truck

Light vehicles in rear-end collision the driver relative to the large vehicles have a high mortality rate which is due to vehicle collision compatibility with different causes of the collision depends on the compatibility of the different characteristics of the vehicle itself, body weight, the former Department of stiffness and shape, which is affecting vehicle crash compatibility an important factor. This article from the real vehicle data of experimental and simulation compatible hit a hit in the rear-end collision in the important role played by, and through simulation analysis of rear-end crash compatibility improvements made research.First, we take a small bridge and medium goods vehicle rear-end collision experiments. Our rule-based on the experimental site, experimental vehicles, experimental data acquisition equipment to do a series of preparatory work, properly controlled experiment, made the desired results and data. By analyzing real vehicle test data, we can understand the medium-sized light truck rear-end car bridge the whole process, including the extent of injury and two car personal injury value.Secondly, the use of 3D modeling and motion simulation capabilities of the rear crash test made a series of research and analysis, through simulation experiments with real vehicle data comparison of experimental data to prove that the simulation model and real car crash experiment consistency, which to further optimize the parameters of the foundation.Finally, considered from the quality, geometry and material stiffness of the three aspects, respectively, before and after the vehicle from the mass ratio, the lower anti-collision device after the vehicle height and stiffness than the corresponding three car simulation analysis, the compatibility of the rear-end collisions of research.This paper describes the concept vehicle crash compatibility and research purposes, by the real vehicle model on the basis of experiments, made on a series of rear-end collision accident simulation, hope to arrive that can help improve vehicle compatibility method, can effectively protect the safety of rear-end car and its occupants, but also can reduce car occupant vehicle accident whiplash effect as harm, have a greater practical and theoretical significance.
