Study on Straddled-type Monorail Vehicle Driver's Injury Caused by the Secondary Impact

摘要

Collision accidents of Monorail vehicles often result fatal injuries to the drivers, which become important subjects. Research on the safety of vehicle collision has become main study topic in the area of urban rail transit. With the development of explicit finite element technology, it is a very good choice to adopt numerical simulation test methods to do research on crash problems. It takes Chongqing straddle-type monorail vehicle as the major object. First, the finite element models of a straddle-type monorail vehicle and dummy were presented. Numerical simulations by computer have been considered as the primary means for crash simulation of vehicle body. The types of thoracic injuries, injury mechanisms, and injury tolerance were analyzed and compared with European and American standards. Achieve comprehensive and credible appraisement with the frontal crash process and crash performance.
