In this paper the influence of the deformation or structural failure in motorcycle accident reconstruction is addressed. Accident reconstruction is important for legal processes and road safety to determine the conditions and events that led to the accident. For the reconstruction of the accident, the software PC-Crash is used with multibody models for the vehicle and driver. The question addressed in this work is how the deformation from the collision affects the results of the reconstruction process and if a deformed multibody model of the vehicle should be considered in the simulations. Seven different real accidents are analyzed and the accident reconstruction is performed using deformed and non-deformed models. The inclusion of the deformations in the multibody model did not reveal different results in the computational simulations comparing with the multibody model without considering the deformations. It is expected that the post-impact movement of a motorcycle multibody model is not considerably influenced by the consideration of the frontal deformations. Failure analysis revealed to be an important complement of accident reconstruction when the accident is or not connect to failure of some parts.

摩托车事故重建:结构变形或破坏的影响

本文探讨了变形或结构破坏对摩托车事故重建的影响。事故重建对于法律程序和道路安全确定导致事故的条件和事件很重要。为了重现事故,将PC-Crash软件与车辆和驾驶员的多体模型配合使用。这项工作解决的问题是,碰撞产生的变形如何影响重建过程的结果,以及在仿真中是否应考虑车辆的变形多体模型。分析了七种不同的实际事故,并使用变形和非变形模型进行事故重建。与不考虑变形的多体模型相比,在多体模型中包含变形并没有在计算仿真中显示出不同的结果。可以预期,摩托车多体模型的碰撞后运动不会受到正面变形的影响。当事故与某些部分的故障相关或不相关时,故障分析显示为事故重建的重要补充。
