刚度是汽车钢板弹簧设计、设计验证及满足整车性能的重要参数,也是判断板簧合格与否的指标之一,因此分析刚度的影响因素,对我们在实际检测过程中找出刚度不符合设计要求的原因有极大帮助。 由金属机械性能及材料力学得知:构件的刚度在构件的形状、尺寸不变的情况下,主要取决于所用材料的弹性模数,而汽车板簧的刚度从理论上说主要决定于板簧所用材料的材质、材料的几何尺寸、设计的总片数、两吊耳中心距,但板簧是多片重叠组合体,片与片间在受载荷的情况下存在摩擦力。由于
Stiffness is the automobile leaf spring design, design validation and meet the vehicle performance is an important parameter, but also determine whether the compliance of the leaf spring index, so the analysis of the factors affecting the stiffness of the actual test we find the stiffness does not meet the design Reasons for asking have great help. From the mechanical properties of metals and materials mechanics that component rigidity in the shape and size of the case, depending on the elastic modulus of the material used, and the stiffness of the automotive leaf spring in theory, mainly determined by the leaf spring The material used, the geometry of the material, the total number of sheets designed, the center distance between the two lifting lugs, but the leaf spring is a multi-lamination combination with friction between the sheets and the sheet under load. due to
