The innovative method of modeling and kinematics simulation in RecurDyn are proposed, taking a Mecanum wheel\nplatform(MWP) for omnidirectional wheelchair as research object. In order to study the motion characteristics and mobile\nperformance of the MWP, the virtual prototype simulation model is established in SolidWorks, and virtual prototype simulation is\ncarried out in RecurDyn.Theexperience of simulation for theMWPin RecurDyn is introduced, and the simulation steps and points\nfor attention are described detailedly. The working states of the mobile system in real environment have been simulated through\nvirtual simulation experiments. Four typical motion models including moving forward, moving laterally, moving laterally in the\ndirection of 45âË?Ë?, and rotation have been simulated in RecurDyn. The simulation results exactly reflect the motion of the MWP.\nBy comparing the simulation results with the theoretical results, there are acceptable errors that are relatively less overall in the\nsimulation results.The simulation results can be used to predict the performance of the platformand evaluate the design rationality,\nand design quality can be improved according to the exposed problem. This paper can provide reference for the simulation of mobile\nplatform by using RecurDyn.
