In this paper, a elastic-plastic dynamical constitutive model on jointed rock masses under blasting load is established with the help of the multiple rigid-body dynamics and contact-impact theory.

运用多刚体系统动力学及接触冲击理论建立了节理岩体弹塑性动态本构模型。

Compared to bevel gear, hypoid gear has larger overlap coefficient, lower gear contact stress, more smooth transmission, lower impact and noise, higher load bearing capacity, longer life and so on.

准双曲面齿轮与普通圆锥齿轮相比，具有重合度大、齿面接触应力低、传动平稳、冲击和噪音小、承载能力高和寿命长等优点。
