By using finite element method and taking bolt material elastic-plasticity into consideration, the distribution laws of inner force and stresses in and deformation of a general triangle screwed bolt under the action of axial force were numerically calculated and analyzed.
采用有限元数值模拟方法,考虑螺栓材料的弹塑性性质,计算分析普通三角形螺纹螺栓&螺母副在轴向力作用下的内力、应力和变形规律。
The influence of bolt action force to the mechanical property of rocks
锚杆对岩土体作用的力学本质
At the same time, the pressure of the pump station, the displacement state of the hydraulic cylinder, the state of the displacement error and the bolt action are being real-time displayed, which make things easy for the operators to monitor on-site equipment.
同时,泵站压力、液压缸位移状态、位移误差和插拔销到位状态的动态显示,方便了操作人员对现场设备的监测。
It is of bullpup layout, and utilizes the most conventional gas operated, rotating bolt locked action, with detachable box magazine feeding.
