Dynamic torque generated by the axial preload bolt preload to meet the engineering requirements.下线/线上检测——静态扭矩Static torque静态扭矩(Static torque): 一个紧固件被紧固好之后，将其在拧紧方向上继续旋转的瞬间所需要的扭矩。静态扭矩是在紧固之后测量的。 Static torque, measured after the fastener is tightened, is equal to the torque when fastener continues to rotate in the direction of tightening needed. Static torque is measured after tightening.检测扭矩（Audit torque）： 静态扭矩标准时用来监控生产过程的稳定性，因此又称为检测扭矩。 Static torque standard used to monitor the stability of the production process, so-called audit torque.没有加速度产生No accelerations动态扭矩和静态扭矩Dynamic torque and static torque表面间的摩擦系数螺纹副的摩擦系数涂层支撑件的粗糙度涂表面处理残余力矩static torque人、机、料材料松弛动态力矩Dynamic torque螺栓硬度、批次工件材料、几何形状、连接特性动态扭矩和静态扭矩Dynamic torque and static torque 生产过程中in manufacture process 下线检测offline test哪个扭矩值更重要？Which one is important?重要！重要！动态扭矩和静态扭矩Dynamic torque and static torque动态力矩—生产过程中的扭矩 可以监控、反应拧紧装配过程的状态、结果以及工艺能力×√动态扭矩和静态扭矩Dynamic torque and static torque残余扭矩—检测扭矩 拧紧装配完成后，相对稳定的螺栓连接状态×√这样一个现象One phenomena动力工具Power tool动态扭矩Dynamic torque手动扳手Manual wrench静态扭矩Static to
