| 摘 要： | 300 MN模锻水压机原主分配器阀体体积较大、阀芯布置不合理、工艺孔多.通过采用凸轮机构式分配阀芯开启方式,重新布置阀芯位置,优化设计了阀体内部结构.以阀体体积最小为优化目标,以阀体强度为主要约束条件,采用有限元方法,对阀体主要结构参数进行灵敏度分析,确定了优化设计变量,对阀体进行了优化设计.优化后阀体体积和工艺孔数量大幅度减少.

| Abstract: | The original volume of main distributor valve-body of 300 MN mould forging hydraulic press was rather big,unreasonable in valve-core arrangement and excessive in technological holes.BY means of adopting the cam mechanism typed opening mode of distribution valve-core,the position of valve-core was rearranged and the inner structure of valve-body was optimally designed.Taking the minimum volume of valve-body as the optimization target,the strength of valve-body as the main restraint condition and adopting the finite element method,the sensitivity analysis was carried out on the main structural parameters of valve-body.The optimal designing variables were determined,and the optimization design on valve-body was carried out.The volume and the number of technological holes of valve-body were reduced to a large extent. |
