摘要: 转子系统动力学仿真中模型建立、支承设置、网格划分、约束设置等操作导致计算分析效率低,且操作繁琐易导致设置遗漏或误触.针对此问题,提出一种转子系统动力学仿真平台,实现了转子系统参数化建模与自动化仿真,提升了转子系统的仿真效率.首先,采用ACT(application customization toolkit),Python和XML联合设计的方法,对参数化建模模块和动力学仿真模块进行界面、功能、数据传递的设计.然后,在仿真实例中详细展示了此平台的工作流程、具体功能和仿真结果.最后,通过现有转子实验台对仿真平台进行实验验证,结果表明,仿真和实验的误差较小,证明了仿真平台的可行性和有效性.

Abstract: In the rotor system dynamics simulation, operations such as model establishment, support setting, mesh division, and constraint setting result in low calculation and analysis efficiency, and the cumbersome operation can easily lead to omissions or false touches of settings. Aiming at this problem, a rotor system dynamics simulation platform is proposed, which realizes the parameterized modeling and automatic simulation of the rotor system, and improves the simulation efficiency of the rotor system. First, using the combined design method of ACT (application customization toolkit), Python and XML, the parametric modeling module and dynamics simulation module are designed for interfaces, functions, and data transfer. Then, the workflow, specific functions and simulation results of this platform are demonstrated in detail in the simulation example. Finally, the simulation platform is verified by the existing rotor experiment platform. The results show that the error between the simulation and experiment is small, thus proving the feasibility and effectiveness of the simulation platform.
