Analysis of Two High Fall Methods Using Multi-rigid Body Models
A multi-rigid body model was used in this study to simulate and reconstruct two disputed falling methods in practical cases.The MADYMO software was used to simulate and calculate the landing position and force point of the human body when falling from a window,and to analyze the physical parameters of the main parts of the body.The results showed that when the human body fell from a window in a straddle position,the trajectory of the fall was tilted to the side,and the side of the body landed first.When the human body fell from a window in a clinging position,the trajectory of the fall was straight and vertical,and the lower limbs of the body landed first.Combining with the fact that the most severe fractures in the case occurred in the lower limbs and pelvic region,it was suggested that the first landing position of the human body when falling is the lower limbs,which was consistent with the multi-rigid body human body model simulation analysis of the falling process in a clinging position.Therefore,the analysis believes that the human body falling injury in the case is consistent with the human body falling from a window in a clinging position.Based on practical cases,this study used a multi-rigid body model to analyze and reconstruct the process of human falling,providing a new visualization method for the analysis of falling injuries and the auxiliary judgment of falling properties.
