Research on design of cars' simulated collision based on object-oriented technology

According to the technical characteristics of control-staff-type car collision platform car test system,the work principles of control-staff-type mechanism of absorbing collision energy and computation model of control-staff design were analyzed.By adopting object-oriented technology,computation software of car collision simulation control-staff was developed. The absorbing energy mechanism of the control-staff designed with this software can simulate the dynamic process of car collision with high design accuracy.
