Dynamic analysis of the actuated redundantly parallel seismic simulator by using the virtual prototype software

The process of building the virtual prototyping and the dynamic analysis of a kind of actuated redundantly parallel seismic simulator was carried out by using the solid modeling software SolidWorks and the multibody dynamics software ADAMS.The virtual prototyping was built by virtue of SolidWorks and ADAMS.Then the position,the velocity,the acceleration of the sliders,the driving torque and power were calculated when the motion of the moving platform was defined in ADAMS.Finally,the required output work was also achieved by means of PostProcessor.The simulation results show that the maximal driving torque,the maximal driving power and the output work of the 3rd motor are biggest among all the motors according to the given trajectory.The whole process reveals the advantages of the virtual prototyping technique since it not only reduces the work of complex modeling and programming,but also completes the dynamic analysis of the parallel seismic simulator rapidly for the building of the prototype.
