摘 要:
渐变刚度钢板弹簧在汽车中有广泛的应用。目前,汽车钢板弹簧的计算方法主要有共同曲率法和集中载荷法,但用这些方法计算副簧为变截面簧片的渐变刚度钢板弹簧时,适应性不好、精度不高。本文建立了具有该结构形式的渐变刚度钢板弹簧的普遍适用的力学模型,提出了一种计算分析渐变刚度钢板弹簧刚度特性的曲率-载荷混合法,通过对某型铃木汽车的渐变刚度钢板弹簧刚度的实例计算及与实验值比较,表明本文提出的曲率-载荷混合法简便易行且有较好的精度。[著者文摘]

Abstract:
Leaf springs with variable stiffness are widely used in automobiles. There are two analytical methods for calculating the properties of the leaf spring with variable stiffness： the same curvature and the concentrated force methods. However, two methods are limited to calculate the properties of the leaf springs with the variable stiffness. A new physical model of the leaf spring with variable stiffness in the form of structures is developed and a curvature-force hybrid method for calculating the properties of the leaf springs with variable stiffness is presented. Simulation results of the Suzuki car leaf springs with variable stiffness indicate that the curvature-force hybrid method is simple and has high precision.[著者文摘]
