活塞环岸的强度验算

Checking Calculation for Strength of Piston Land

本文将活塞环岸视为内边固定外边自由的环形圆板,根据圆板弯曲理论,计算因环岸上下面压强不同产生的弯曲正应力,为环岸的强度验算提供了较为可靠的计算方法。

In this paper, the piston land is recognized as a ring circular plate, which is fixed at the internal circumference and free at the external. According to the bending theory of the circular plate, the calculation was made to obtain the bending stress caused by the difference of compression in the upper and lower side of the piston land. Then, this checking calculation of strength for piston land provides a more reliable method for calculation.
