基于Simulink和Comsol联合仿真的虚拟热试验系统

Virtual Thermal Test System Based on Simulink and Comsol Co-simulation

通过Simulink和Comsol软件联合仿真搭建虚拟热试验系统,实现热试验的完全虚拟化;利用联合仿真技术,实现对控制系统、电场、热场的综合仿真分析;可一次性直接观测各个观测点数据状态,包括功放输出状态信息、加热器输出状态信息及被试件热热状态信息。虚拟热试验系统对工程热试验具有预示和指导作用,可以实现超出现有热环境地面模拟能力的热环境模拟,为型号的研制提供依据。

A virtual thermal test system was produced using the co-simulation of Simulink and Comsol to realize the complete virtualization of the thermal test.The co-simulation technology enabled the comprehensive simulation analysis of the control system,electric field,and thermal field.The data states of every single observation point can be acquired directly,including the output states information both of the power amplifier and the heater and the thermal states information of the test.The virtual thermal test system has a predictive and guiding role for engineering thermal tests and is capable to simulate the thermal environment beyond the actual existing thermal environment,thus providing a basic tool for the future development of models.
