为实现一般多体系统动力学计算和结果的可视化仿真，在研究开源动力学代码MBDyn的基础上，设计并实现了多体系统可视化仿真软件( MBDynSimCenter)。采用虚拟原型的思想，集成了Open Cascade建模框架，实现了多体系统可视化建模前处理器。设计了MBDyn求解器计算接口模块，自动求解多体系统动力学问题。开发了曲线绘制及动画分析后处理器。用曲柄滑块机构的仿真算例，验证了软件的有效性和正确性。仿真结果表明该软件能够满足一般多体系统动力学可视化计算仿真的要求。

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.
