The dynamic load which is produced by road excitation may have destructive effect on some critical parts of rocket launcher during the vehicle rocket launcher is running,and also have destructive effect on service life of the rocket launcher.The running vehicle-mounted rocket launcher rigid-flexible coupling model was set up by means of analysis of topology structure and RECURDYN 、ANSYS software.In the course of model establishment,take the beam as flexible bodies.Six road spectrums were made according to the military standard.The corresponding response parameter was obtained by the ride analysis in view of six state of roads.Dynamic simulation can provide reference for general design and part design of vehicle rocket launcher.
Key words: dynamic load; rocket launcher; beam; the road spectrum; rigid-flexible coupling
