动力摩擦 meaning in English
dynamical friction
kinetic friction
Examples
- Based on the analysis , we gave an example to study the dynamic contact with friction of the intermittent joint , and got some essential rules : the friction coefficient could n ' t influence the distributing of dynamic stress on the contact surface , and the roading rates affected evidently on the dynamic characteristic on the contact surface . in the last part , this paper made respectively use of the time - history method and the response spectrum method to analyze the dynamic response of the rock slope on baise hydraulic power plant , and got the coincident resultant . simultaneously , the contact theory was applied to study the stability of the intermittent joints
基于上述的接触理论和接触分析结果，本文在最后一部分中分别利用动力时程法和反应谱法对百色水电站尾水渠的岩质边坡进行动力响应分析，两者计算方法得出比较一致的结果，同时采用动力摩擦接触理论重点分析了断层对于边坡的稳定影响，认为断层的存在会使得岩坡的稳定性降低，在地震等动力荷载的作用下对于断层将发生张开、闭合和错动现象，尤其是动力荷载和其他荷载如渗流力等的耦合作用将会对断层产生极为不利的后果，进而影响岩坡的整体动力稳定，应该要引起足够的重视。 - This paper summarized the characteristic and localizations of the special contact elements that can simulate the joints in rockmass . except for those , three kinds of numerical methods for dynamic contact analysis were introduced . then , the augment lagrangian method that combined lagrangian multiplier and penalty function was applied to the dynamic contact analysis with friction
