基于摄动理论的汽车二维碰撞模型抗干扰性分析

Analysis of Perturbation Resistance of Vehicle Two-dimensional Impact Models on Perturbation Theory

目前国内外的汽车事故再现模型主要基于动量定理来分析的。通过对典型的汽车二维非对心点碰撞模型分析求解计算,并且基于摄动理论,应用数学方法分析模型的抗干扰能力。通过理论分析,提高模型计算的准确性和可靠性。

At present the models of vehicle impact accident reconstruction were analyzed based on the theorem of momentum both home and abroad. The methods were analyzed by using the typical vehicle non-center-to-center two-dimensional models. Then, the mathematical methods based on Perturbation Theory were used to analyze perturbation resistance of the models. By theoretical analysis, the veracity and reliability were improved for calculating models.
