一、前言本刊曾以“从实际产品看杠杆弹性支点的优点”为题介绍了板簧支点。这次,作者准备把板簧支点与刀刃支点做一对比,说明杠杆支点的一些注意事项。然后以二、三个产品为例,介绍板簧支点的优点。二、简单板簧的变形在图1中,板簧的长度为1,弯曲刚性为 EI,上端 A_1的固定倾斜角为θ_1,它的下端 A_2受

First, the foreword Articles have been “from the actual product to see the advantages of leverage fulcrum ” for the title introduced the leaf spring fulcrum. This time, the author plans to compare the fulcrum of the leaf spring with the fulcrum of the blade to show some cautions about the fulcrum of the lever. Then two or three products, for example, introduce the advantages of leaf spring fulcrum. Second, the simple leaf spring deformation In Figure 1, the length of the leaf spring 1, the bending stiffness of EI, the upper end of the fixed tilt angle A_1 θ_1, its lower end A_2 by
