With the rapid development of railway passenger cars, higher requirements of vehicle driving safety is put forward. Railway passenger cars in our country have measuresin the active safety, but the vehicle passive safety aspects are not mature. In recent years, with the High-speed Rail era, the passive safety protection technology caused great concern, and has e a hotresearch in the design of railway passenger car. Most of the international project on the body of the collision energy absorption also have specific passive safety technology of railway passenger car body is very necessary and concepts of railway passenger car body of the collision resistance and design standard
