现在对制造消耗金属少的少片弹簧,已积累了足够的经验,这就能够使以前得到的少片弹簧的计算关系更加精确。[1～3]众所周知[1和4],少片弹簧在大多数的情况下,乃是由一片或相同长度的几片组成。例如,用于载重汽车的三片弹簧(图1),其中部和端部为等断面,而介于它们之间的部分是变断面的。为了提高弹簧的寿命,在中部设置了片间衬垫。因为这种弹簧是用来代替由 Now that we have accumulated enough experience in the manufacture of a small piece of spring that consumes less metal, this makes it possible to make the previously calculated calculation of the spring less accurate. [1 ~ 3] As we all know [1 and 4], less pieces of spring in most cases, but by a piece or a few pieces of the same length. For example, a three-piece spring (Figure 1) for a truck, with a central section and an end section in a constant cross-section, with the section between them being variable in cross section. In order to improve the life of the spring, an interlabial padding is provided in the middle. Because this spring is used instead of by
