摘要
大功率液力变速器试验台是大功率液力变速器生产企业常用的一种试验装备,试验台底座对试验台整体性能具有重要的影响。在原有试验台驱动及前加载底座结构的基础上,采用ABAQUS对底座的动态性能进行分析,研究了不同元结构及不同约束布置形式对底座动态性能的影响规律,并在对底座拓扑优化的基础上对底座的筋板进行了尺寸优化。对优化前后底座进行了比较分析,得到优化后的底座在重量减轻17.75%的同时,一阶固有频率提高26.27%。研究结果为同类型的试验台底座设计提供了有效的设计指导。
High-power hydraulic transmission test-bench is one kind of the most commonly used test-bed in high-power hydraulic transmission manufacturing companies.The base has an important influence on the test-bench.Based on the structure of the original driving and the front loading base of test-bench,ABAQUS was used to analyze the dynamic performance of the base.This paper studies the influence of different ribbed slab arrangement and different constraint arrangement on the dynamic performance of the base.Then,on the base of topological optimization base,the dimension of the ribbed slab is optimized.Compared with the base before and after the optimization,the optimized base was reduced the weight by 17.75%and the natural frequency of the first-order increased by 26.27%.The results provide effective design guidance for the design of the same test bench base.
