static friction force

The article reports experiments which show that the maximum static friction force F on the surface of an aluminum rod inserted in the dry granular.

用实验方法研究了简仓内大小均匀的颗粒堆中央的竖直探测棒被提拉时受到的最大静摩擦力F。

Any hypothetical force postulated to either push or pull oceanic plates would be quickly dissipated overcoming the friction of sliding over a static fluid mantle beneath.

任何假设的能推动或拉动大洋板块的力，会很快因克服在其下静态的热体地幔上滑动的摩擦力而被消散。

Hertz contact model was used to deal with normal impact force, and Hertz tangential contact model and Coulomb friction model were used to deal with static tangential impact force and slip frictional force, respectively.

用Hertz接触模型处理法向撞击力，分别用Hertz切向接触模型和Coulomb摩擦力模型处理粘滞状态和滑动状态的摩擦力。

The results showed that the sliding ratio of ground-contact tread, the sliding force ( F_ ( sx)) and the adhesion force ( F_ ( ax)) increased as the static friction coefficient increased;

结果表明，随着静摩擦因数的增大，接地胎面完全滑移的滑移率增大，滑移力（Fsx）和附着力（Fax）增大；

Sliding friction force is always smaller than force of maximum static friction.

滑动摩擦力总是比最大静摩擦力要小.
