The production mechanism of the surface residual stress producing in grinding process is the combined effect on extrusionstress and the cutting stress and the thermal load.
The variation laws of wearing character on V - packing are studied in the whole working life. The wearing character include the friction force, axial extrusionstress and axial pressure distribution.
对V形密封在整个工作寿命中，轴向挤压应力、轴向压力分布、摩擦力等特性变化进行实验研究。
