On the basis of Based on the Matlab/Simulink simulation software, the simulation model of bilinear restoring force is established. By the dynamical model of the non-linear hysteresis vibration system and simulink emulator program, the non-linear hysteresis vibration system is analyzed and simulated. The result shows that the simulink software is easy for programming and has high reliability, by utilizing it to simulate the non-linear vibration system, the time domain curves of displacement, speed and accelerated speed can be gained very easy.
