This paper presents the design of multi-steel leaf springs for the dependent suspension system of light trucks model KIA FRONTIER K165 using computer-aided calculations. The multi-steel leaf springs are tested and evaluated for safety according to durability calculation criteria by using two methods: (a) traditional design and (b) Finite Element Anlysis method (FEA). The durability of the multi-steel leaf springs is examined by the support of the Optistruct module in Hyperworks. The stress and strain of leaf springs under vertical loads are calculated by the FEA. The range of vertical loads acting on the tweezers is changed from 1000 10000 N. The results of the FEA stress and displacement calculations show that the maximum positive deviation compared with the traditional method are no more than 15% and 1.5%, respectively. The results show that, FEA can be used to determine the stress and displacement to increase the efficiency of the design process of the truck springs.
