一、工程中的微动磨损微动损伤是工程中广泛存在的现象,它可分为两大类,第一类为原设计时接触面是永远相对静止的,由环境振动或配合组元之一受到交变应力引起微动。如各种压配合,铆接,螺栓(钉)、榫槽、锥套、珐兰联结等;键、销固定,弹簧密封面或支承面,电插接件等。第二类为各种运动副停止运转 First, the project fretting fretting Fretting damage is a widespread phenomenon in the project, which can be divided into two categories, the first category is the original design of the contact surface is always relatively static, from the environment or with the component of the vibration As a result of alternating stress caused by fretting. Such as a variety of pressure with, riveting, bolts (nails), mortise, taper sets, such as enamel coupling; keys, pin fixed, spring sealing surface or bearing surface, electrical connectors. The second category for a variety of sports teams to stop functioning
