摘　　要：针对重型特种车辆悬架用螺旋弹簧载荷大、行程大、布置空间有限的特点,设计了一种变丝径螺旋弹簧,在满足承载能力和行程需求的同时还考虑了刚度拐点的设计;推导了变丝径螺旋弹簧压并载荷及等效刚度计算方法;利用螺栓弹簧刚度特性台架试验对理论计算的准确性进行了验证。The features of suspension helical spring on heavy-duty vehicles include heavy load,long stroke and limited space.Therefore a variable-diameter helical spring was designed to meet the load capability and stroke requirements,while also considering the inflection point on the stiffness curve.The calculations to obtain the compression load and equivalent stiffness were derived.In addition,the bench test was implemented to check the accuracy of stiffness characteristic calculation.
