ABSTRACT: A collision model, an automobile model and a multi-rigid-body model in
PC-crash are analyzed. By simulating a side collision accident between a car
and an electric bicycle (EB), a method that reproduces the car-electric bicycle
side collision accident based on PC-crash is presented according to some
important information such as the final position, the contacting location between
the cyclist and the car. A result is obtained by comparing with the reproduced
result, the deformation of accident vehicle and the surveillance video. The rollover
direction and fells-over sliding direction after the collision and the
contacting location and wrap motion of cyclist and electric bicycle are fitting
in with the real situation better compared with the reconstruction result in
PC-crash. Then the responsive-surface method and MONTEKARLO method are used in
MATLAB to analyze the uncertainty of the vehicle speed in reproduced scene
results. And the range of values of the pre-collision speed is obtained which
makes the reproduced result more objective and convincible that could provide
the basis of the accident assessment.
