运用APDL参数化建立了7层橡胶钢板组合弹簧的有限元模型,对其在装配状态下的接触应力进行了分析,得到了其装配荷载下的应力云图。并同下列2种情况作了比较:1与层数、厚度相同的钢板弹簧做了比较;2层数不变,只增加橡胶层的厚度进行比较。结果表明,在相同的装配荷载下,组合弹簧各层的应力都比钢板弹簧的小,即其承载能力比钢板弹簧高,而且橡胶层的厚度越厚,其承载能力越高。 The finite element model of 7-layer rubber-steel composite spring was established by using APDL parameterization. The contact stress under assembly condition was analyzed, and the stress cloud under assembly load was obtained. And compared with the following two cases: 1 with the same number of layers, the same thickness of the leaf springs were compared; 2 unchanged, only increasing the thickness of the rubber layer for comparison. The results show that under the same assembly load, the stress of each layer of composite spring is lower than that of leaf spring, that is its carrying capacity is higher than that of leaf spring, and the thicker the rubber layer, the higher its carrying capacity.
