发动机冷测试是通过高精度的仪器和测试传感器来探测发动机的工况,通过数据分析对比来判定发动机的装配质量。冷试设备一般包含机械系统、控制系统和数据采集分析系统三大系统,冷试设备的失效模式主要体现在机械结构方面,文章结合实际案例进行论述,并提出了相应的解决方案。 Engine cold test is through high-precision instrumentation and test sensors to detect the engine condition, through the data analysis to determine the quality of the engine assembly. The cold test equipment generally includes three systems of mechanical system, control system and data acquisition and analysis system. The failure mode of cold test equipment is mainly reflected in the mechanical structure. The article discusses the actual case and presents the corresponding solutions.
