In order to realize the dynamics calculation of general multibody systems and the visual simulation of the results,a multibody system visual simulation software(MBDynSimCenter)is designed and implemented based on open source multibody dynamics analysis code MBDyn.Using the idea of virtual prototype,the Open Cascade modeling framework is integrated,and a preprocessor for multibody system visual modeling is realized.A calculation interface model of MBDyn solver is designed to solve multibody dynamics problems automatically.A powerful post-processor for curve drawing and animation analysis is developed.The crank-slider mechanism simulation example verifies the validity and accuracy of the software.Simulation results show that the software meets the requirements of the visual simulation of general multibody system dynamics.
