基于ANSYS分析的安全阀研磨支架优化设计

针对目前安全阀阀座维修效率低，劳动强度大的难题，开发出新型阀座研磨维修设备。采用SolidWorks软件建立研磨机构三维实体模型，根据理论力学原理对支架梁结构进行受力分析，将分离的支架模型导入Workbench中。基于ANSYS静力学分析理论，对支架机构进行静力学分析，分别得到应力云图、变形云图。依据工程材料轻量化设计原则，对支架进行综合优化设计，并从理论上验证支架结构的安全性能。对比优化前后支架主要参数的变化，结果表明：优化后支架的质量和体积减少38. 7%，有效降低了生产成本。

Optimization Design of Safety Valve Grinding Mechanism Based on ANSYS Analysis

ln order to solve the difficult problems of low efficiency repair and labor intensity of the present safety valveseat, a new type of valve seat grinding equipment was designed. By using SolidWorks software, the 3D model of grindingmechanism was established. According to the principle of theoretical mechanics, the stress analysis of support beam wascarried out, and the detached scaffold model was imported into the Workbench. Based on ANSYS static analysis theory,statics analysis was carried out on the support mechanism. The stress nephogram and displacement contours wereobtained. According to the principles of lightweight design among engineering materials, integrated optimization designof the bracket was considered, and the security performance of framework also was validated in theory. By comparing thechange of the main parameters before and after the support, the results show that quality and volume of the optimizedsupport decreases by 38.7% , and the production cost reduces effectively.
