摘要
为了测试飞机发动机活门组件的综合性能,开发了一种新型试验器.试验要求活门组件入口处的温度应为(20±2)℃,因此,必须设计一套闭环温度控制系统来保证温度的恒定.所提出的温度控制系统方案,介绍了工程实际中较易实现的温度控制方法及温度系统数学模型,并用Simulink软件对温度控制过程进行了仿真.试验表明,该温度控制系统可实现的控制精度为±2℃,满足了试验要求,具有较高的可靠性,为活门组件试验器整体的研制奠定了基础,并提供了一定的理论依据.
In order to test the comprehensive pormances of valve assembly in aircraft engine, a new experimental platform was developed. Because the entrance temperature of （20 ±2 ）℃ for valve assembly is required, it is necessary to design a set of closed loop temperature control system for ensuring the stability in temperature. The temperature control scheme was proposed, and the method and mathematic model for temperature control were introduced. The process of temperature control was simulated using Simulink software. The experiments prove that the temperature control system is simple and dependable, and the measurement precision is ± 2 ℃. This research establishes the basis and provids some theoretical reference for the development of valve assembly experimental platform.
