汽车自动冲压生产线用Y形圈的寿命测试研究

Research on Life Testing of Y-Cup Seals for Automobile Punching Production Line

该文通过有限元分析(FEA)方法,对不同流体压力下的丁腈橡胶Y形圈的唇口最大接触压力和密封耦合面的接触宽度的计算,利用寿命测算的经验公式,采用Y形圈的往复台架测试和实际装机运行寿命跟踪的方法,对汽车自动冲压生产线用Y形圈的使用寿命进行了测试研究。

The through the method of finite element analysis（FEA）, under different fluid pressures of nitrile butadiene rubber（NBR） Y-cup sealing lip maximum contact pressure and sealing coupling surface of the contact width are calculated, using the empirical formula of life expectancy estimates, the use of reciprocating bench test of Y type circle and actual service life tracking method, of automobile automatic stamping production line with the service life of the Y-shaped ring were test research.
