作为减轻钢板弹簧重量的方法,大体有以下三条:a.增加刚度不增加应力;b.增加应力不增加刚度,通过增加片厚减少片数减轻重量;c.通过改变断面形状、各片长度差、片端压延等减轻重量。a 法——随着刚度的增加,减轻重量成为可能,但因舒适性等变坏而受到限制;b 法——对大幅度地减轻重量很有效,但必须解决应力增高后叶片的寿命问题; As a way to reduce the weight of the leaf spring, there are generally the following three: a. Increasing the stiffness does not increase the stress; b. Increasing the stress does not increase the stiffness, by reducing the sheet thickness to reduce the number of pieces to reduce weight; c by changing the cross-section shape, , Sheet-metal rolling and other reduce weight. Method a - weight reduction is possible with increased stiffness but limited by poor comfort; b method - effective for drastic weight reductions, but blade life must be addressed after increased stress;
