查询词典 contact angle

The frictional heat energy was concentrated on the thermal effect layer with the thickness of 4 mm, The temperature gradient of contact surface is the highest, and decreased rapidly with the radius direction of the lining's groove. The temperature gradient and TEL's thickness increased with the increasing of the sliding speed. The temperature decreased rapidly with the radius direction and also with the increasing of center angle of the lining's groove. The sliding speed and distance are obtained under two sliding conditions when the lining fails, which supply the theoretical basis with the antislip design of friction hoist.

摩擦热量集中在热影响表面层，其厚度仅为4mm，接触表面温度梯度最大，沿绳槽径向迅速减小；温度梯度和热影响表面层厚度随相对滑速的增大而增大；衬垫温度沿径向急剧降低且随圆心角增大而减小；并得到了2种滑动工况下衬垫失效时的相对滑速和滑动距离，为摩擦提升防滑设计提供理论依据。
