摘要: 为了发现飞机油门控制器热设计的薄弱环节，保证热设计的合理性和产品的安全性，因而对航空用油门控制器进行了热设计仿真分析研究。介绍了油门控制器的工作原理以及内部结构，采用FloTHERM软件对飞机油门控制器建立热模型，分析其在70 ℃环境温度条件下，位于地面高度与高空飞行高度时的模型内部温度分布规律，找到热设计的薄弱环节。通过热仿真分析结果，指出产品热设计的不足，提出改进意见，避免由于温度过高而造成失效。Abstract: In order to find the weakness of the thermal design of the aircraft throttle controller, ensure the rationality of thermal design and product safety, the thermal simulation analysis of the throttle controller was carried out in this paper. First, the working principle and internal structure of throttle controller were introduced, the thermal model of the throttle controller was established by using FloTHERM software; then, the internal temperature field distribution of the model was analyzed when the throttle controller was located at the ground height and high altitude flight height under the condition temperature of 70 ℃ to determine the weakness part of thermal design. Through thermal simulation analysis, finally, the shortage of thermal design is pointed out, and suggestions for improvement are put forward to avoid damage due to excessive temperature.
