一、问题的提出圆锥形螺旋弹簧属于变刚度弹簧。由于它具有不等的弹簧指数(C=D/d,D为弹簧中径,d为弹簧钢丝直径),并且随着变形程度的增加,参加变形的弹簧圈数将愈来愈少(大端弹簧圈较软,首先变形,当它并紧以后就不再参加工作),所以这种弹簧将愈压愈 First, the question raised Conical spiral spring is a variable stiffness spring. Because of its unequal spring index (C = D / d, D is the diameter of the spring, d is the diameter of the spring wire), and as the degree of deformation increases, the number of deformed coils becomes less and less The coil is softer, deforms first and then stops working when it is tight), so this spring will cure more
