The friction force is therefore called a nonconservative or a dissipative force.

因此，摩擦力称为非保守力或耗散力。

In order to study the influence of structural parameters on the optimal normal load, a microslip model was used to formulate the nonlinear dry friction force.

摘要为了研究阻尼结构参数对阻尼叶片最优正压力的影响，基于微滑移模型，推导出了阻尼器非线性干摩擦阻尼力的计算公式。

Through the reduction of friction force and deformation force between the steel wire and die,the tensile failure problem of steel wire workblank during the stamping process was resolved.

膨胀管的膨胀过程是一种高度非线性行为,解析方法虽然可以近似求出变形力的大小,但很难对膨胀过程进行全面求解。
