Abstract

A multi-objective optimization method for the composite leaf spring of a type of buses is described to optimize the performance of the composite leaf spring. A multi-objective optimization model is established in the genetic algorithm toolbox of Matlab software by using the weighting coefficient transformation method and the hybrid method in genetic algorithms. The variables of the model are parameters of the layer scheme and the stiffness

the strength ratio and the mass of the composite leaf spring are sub-goals of the model. A Matlab program is coded to calculate the performance of the composite leaf spring. The results show that the width of the composite leaf spring should be maximized and the thickness of the composite leaf spring parabolically increases from the end of the layer region with gradient length towards the bump structure. The prototypes of the optimal design scheme are manufactured and a bench test is performed. The test results show that the mass and the fatigue life of the composite leaf spring are 40% and three times of those of the steel leaf spring

respectively. Moreover

the stiffness and the strength of the composite leaf spring also meet the requirements of this type of buses.
