Ascertaining the equivalent point position of the starting point of corner contact on the meshing line,the radius from corner contact to gear center and computation of both of the gears load angle of the corner contact point,it also proposes the calculating method of corner contact impact rate.

建立了考虑摩擦、误差的齿轮副扭转振动模型,从确定线外啮合起点在啮合线上的等效点位置、线外啮合点到齿轮圆心的半径、计算线外啮合点处两齿轮的载荷角等3个方面入手,提出了线外啮合冲击速度的计算方法。

As a result of deformation of gear tooth under load and machining error, gear meshes outside the normal path of contacting line in the gear tooth meshing start location, and gives birth to meshing-in impact and meshing-out impact, also intitules corner contact impact.

由于轮齿的受载变形和加工误差，在轮齿啮合起始位置，齿轮在理论啮合线外发生啮合，产生啮入与啮出冲击，也称为线外啮合冲击，研究表明线外啮合冲击是导致齿轮传动振动、噪声和点蚀破坏的主要原因之一。

A new,more reasonable 2DOF RWIV model was established in which the ever-changing shape of rivulet was simulated for rivulet shape contributes greatly to RWIV,and the stability discriminants of the cable and the rivulet motion were deduced.

首先,建立考虑水线外形变化的斜拉桥拉索风雨激振计算模型,并将由采用变化水线外形的模型得到的拉索最大振幅与固定水线外形模型的计算结果及试验实测结果对比,对模型进行验证;在模型得到验证的基础上,进一步讨论拉索和变化水线外形的水线振动稳定性及水线对拉索风雨激振贡献。
