摘要
文章以汽车零部件中的板簧为研究对象,选取合适的复合材料取代传统的弹簧钢以减轻质量,并通过板簧结构的优化设计进一步减轻质量,最终达到轻量化的目的。在有关复合材料层合板力学相关理论的基础上,利用Matlab中的相关优化函数对板簧结构进行优化设计,在保证板簧优良性能的前提下得到最小质量下的最佳尺寸,然后运用ANSYS对板簧进行了分析,结果表明:优化后板簧质量减少了50%,板簧的疲劳寿命有了大幅度的提高。
The purpose of this paper is to take leaf spring as the research object, to select the appropriate composite materials to replace the traditional spring steel in order to reduce weight, at the same time the structure of leaf spring was further optimized to reduce the weight, and to reach the target of weight reduction. Using MATLAB optimization functions to optimize the structure of the leaf spring on the basis of the relevant composite laminates mechanics theory＇, the optimum dimension at the smallest size of the leaf springs was obtained in the case of ensuring excellent performance of the leaf spring, the leaf spring was analyzed through ANSYS, the results show that the weight of the leaf spring was reduced by 50% after the optimization, and the leaf spring fatigue life has been greatly improved.
