发动机气缸密封垫压缩回弹性能测试技术研究

Research on the Testing Technology of Compression Recovery Performance of Engine Cylinder Seal Gasket

介绍了压缩回弹试验机的整体结构,表述了试验机系统的工作原理。整个系统通过计算机控制进行加载和卸载,利用高精度的光栅尺位移传感器测量垫片的变形量,实现了对发动机气缸密封垫的两个重要参数压缩率和回弹率的自动测量,测量精度较高,应用前景广泛。

This paper introduces the overall structure of the compression-resilience testing machine and describes the working principles of its system. The whole system is controlled by computer for loading and unloading, measures the deformation degree of the gasket by using the raster displacement sensor with high precision and realizes the automatic measurement on the two important parameters of compression rate and resilience rate of the engine cylinder gasket, which is proved to have high measurement precision and wide appli- cation prospect.
