摘要
对一种新型的、用于大型履带式车辆的多层管状减振结构的参数特性进行了研究。在分析了参数之间耦连关系后,提出了暂定刚度参数Y和阻尼材料损耗因子β,先求剪切参数x的解耦观点。把减振结构的几何尺寸作为变量,结构的损耗因子η最大为目标,对结构进行了优化。经对按本文观点优化设计的橡胶减振器制品的动态实验,表明实验值与理论值有着较好的吻合性。
A study is executed for a new type of vibration isolator which consists of multi elastic element structural composites, and presents a tube configuration, used in sprocket assembly of heavy duty crawler vehicles. After analyzing coupling relationships of structural parameters, a viewpoint is brought forward that geometrical parameter Y and damping material loss factor β are temporarily decided before shear parameter x is determined. According to the ones, structural dimensions are regarded as variables and a maximum value of structural loss factors η is confirmed as a target, an optimum action is carried out to the structures. By performing dynamic tests for the isolator products optimized basing on the idea, results show better coincidence between testing and theoretic values.
