The contact deformation at transient engaging point is derived from deeply analyzing geometric property and kinematics relationship between the two action flanks by use of engagement principle, differential geometry, elastic and plastic mechanics, etc.

• 运用啮合原理、微分几何和弹塑性力学等基础知识，对齿面间的几何性质和运动关系进行深入细致的分析研究，计算各瞬态啮合点的接触变形。
