模拟同步带的半实物仿真测试研究

Hardware-in-the-loop simulation test for synchronous belt

针对永磁同步电机测试过程中加载负载繁琐、效率低下的问题,设计了一种硬件在环的半实物仿真测试系统和模拟负载的测试方案。研究同步带带载模型,对同步带空载的工况建模并实验,以验证模型准确性和测试系统合理性。首先分析并建立同步带的传统动力学模型及虚拟样机模型,针对这两种建模方法,对比选择更精确的模型。将模型解算结果加载到测试系统中,得到模拟负载的测试数据,与实测同步带测试数据对比,验证了所建模型的准确性。

This paper presented a hardware-in-the-loop simulation testing system with artificial load to solve the problem,complex loading style and low efficiency in traditional PMSM testing system.A model for synchronous belt was designed and relevant experiments was done to verify the accuracy of the model and the rationality of the testing system.Traditional dynamic model and virtual prototype model were built.Then they were compared and a more accurate model was adopted to load in the testing system.The comparison between the simulation and actual test verified the accuracy of the model.
