Using Pro/E,an entity model of rotary hydraulic cylinder with 360 degrees was built up,And then importing it into ADAMS by using the special interface software(MECH/PRO) between Pro/E and ADAMS,based on the the virtual prototype,the motion simulation of a rotary hydraulic cylinder with 360 degrees was developed.The simulation results indicate that the rotary hydraulic cylinder keeps a stable stance and high precision and easy to control when it rotating,and it's rotary angel reach to 360 degrees.This work provided the theoretical support and...
