This paper points out the disagreement of boundary conditions that generate force discontinuity in the linear spring damping contact model by analyzing the contact modulation of the clearance joint.
分析了含间隙运动副副元素的碰撞分离过程，指出线性弹簧阻尼模型不能满足接触边界条件并产生力突变；
They were all treated with straight wire appliance and helical spring to expand clearance.
均采用直丝弓矫治器矫治，应用螺旋推簧扩展间隙及上颌前方牵引。
In the operation of automatic spring coiling machine, the user needs to check the clearance between the parts, the use of the locking screw handle, screw tightening is loose.
在自动卷簧机的操作方面，用户需要检查零件之间的间隙、锁紧螺丝手柄的使用效果、螺丝拧紧是否有松动。
Continue to back out the service bolt until sufficient clearance is achieved to remove the complete spring mechanism.
继续撤出维修螺栓直到有足够的空间拆卸整个弹簧装置为止。
