为解决单一构建三弯矩法数学模型和多体动力学分析轴系校中存在局限性的问题，提出基于Matlab与SimulationX联合仿真的解决方案。首先介绍Matlab与SimulationX联合仿真的运行机制，分析2种仿真软件实现协同仿真的技术可行性。基于多体动力学以及轴承动态特性，综合考虑整体轴系系统实现轴系动态校中。采用该方法计算，其结果符合轴系校中规范且各同类轴承载荷更为均衡。该协同仿真方法不仅可用于轴系动态校中研究，也为其他多物理场耦合问题研究提供了解决思路。
In order to solve the problem of limitations in the study of single construction of mathematical model of three-moment method and shafting alignment of multi-body dynamics analysis. A solution based on Matlab and SimulationX co-simulation was proposed. Firstly, the operation mechanism of Matlab and SimulationX joint simulation is introduced, and the technical feasibility of two kinds of simulation software to realize collaborative simulation is analyzed. Then based on multi-body dynamics and bearing dynamic characteristics, the whole shaft system is considered to realize dynamic alignment. Under the calculation of this method, the results conform to the shafting alignment specification and the load of each similar bearing is more balanced. The co-simulation method not only provides a method for the study of shafting dynamic alignment, but also provides a solution for other multi-physics coupling problems.
