复合材料副簧刚度的匹配设计方法
|
Abstract:
为了对复合材料副簧的刚度进行匹配设计,设计了包含有复合材料副簧的主副簧总成结构。采用集中载荷法计算复合材料副簧的等效载荷,根据原钢板弹簧的挠度变化来估算复合材料副簧的等效刚度。根据钢板弹簧设计理论,对复合材料副簧的等效刚度进行匹配设计。采用ABAQUS软件对设计的主副簧总成的总刚度进行有限元模拟,通过调整复合材料副簧的铺层数量来修正复合材料副簧的等效刚度。提出的匹配设计方法对复合材料板簧的推广应用具有重要意义。 In order to matching design the stiffness of composite auxiliary spring, the structure of the main-auxiliary spring assembly structure, which includes a composite auxiliary spring, was designed. The equivalent load of the composite auxiliary spring was calculated by the concentrated load method. According to the change of the deflection of the original steel leaf spring, the equivalent stiffness of the composite auxiliary spring was estimated. The equivalent stiffness of the composite auxiliary spring was matching designed according to the design theory of steel leaf spring. The finite element simulation for the total stiffness of the main-auxiliary spring assembly was made by ABAQUS software. By adjusting the ply number of the composite auxiliary spring, the equivalent stiffness of the composite auxiliary spring was modified. The proposed matching design method processes great importance for the popularization and application of composite leaf spring. 国家自然科学基金(51205158);中国博士后科学基金面上资助项目(2013M541294);吉林省重大科技专项(212E362415);吉林大学研究生创新基金(450060503159)
