【摘要】：人-車碰撞事故中通常包含不確定因素,根據(jù)這些取值不確定的參數(shù)估算車速,具有不準(zhǔn)確性。提出一個基于汽車-行人第一落地點的碰撞車速計算模型,可應(yīng)用于行人拋距不可靠的情況下。為了提高該模型碰撞車速計算的準(zhǔn)確性,引入了再現(xiàn)車速不確定度理論的評定方法。結(jié)合一起轎車與行人的碰撞事故,計算出行人第一落地點車速模型的車速最優(yōu)取值范圍。通過PC-Crash、MADYMO模擬仿真驗證及與拋距模型車速計算結(jié)果的對比,驗證上述車速計算分析流程的可行性與合理性。
[Abstract]:The uncertain factors are usually included in the man-vehicle collision accident. It is inaccurate to estimate the speed according to these uncertain parameters. A collision speed calculation model based on the first landing place of vehicle and pedestrian is proposed, which can be used in the case of unreliable pedestrian throw distance. In order to improve the accuracy of calculating the collision speed of the model, an evaluation method based on the theory of reproducing the uncertainty of the speed is introduced. Combined with a collision accident between passenger car and pedestrian, the optimal range of vehicle speed is calculated. The feasibility and rationality of the speed calculation and analysis flow are verified by comparing the simulation results of PC-Crash-MADYMO and the speed calculation results of the throw distance model.
