阀门执行器箱体加强筋优化设计与分析

Optimal Design and Analysis of Reinforcing Ribs of Valve Actuator Box

阀门执行器是用于控制阀门启闭的元件。为了验证某阀门执行器的抗爆性能,对执行器箱体进行了有限元分析,发现箱体抗爆性不足。对箱体进行拓扑优化设计,得到了箱体的传力路径,根据拓扑优化的结果对箱体进行第一次设计,分析表明第一次设计的结果满足使用要求。为了实现箱体的轻量化,对箱体加强筋进行基于响应面法的尺寸优化,得到了最优的加强筋截面尺寸,根据优化尺寸对箱体进行第二次设计,分析结果表明,在满足使用要求的前提下,第二次设计的加强筋质量相比第一次减轻36%,达到了轻量化的目的,证明了优化设计的合理性和可行性,并为箱体的相关设计提供了借鉴和参考。

The valve actuator is a component used to control the opening and closing of the valve.In order to verify the anti-explosion performance of the valve actuator,the finite element analysis of the actuator box was carried out,and it was found that the anti-explosion performance of the actuator box was insufficient.Based on the topology optimization design of the box,the force transmission path of the box is obtained.According to the results of the topology optimization,the box is designed for the first time.The analysis shows that the results of the first design meet the requirements of use.In order to realize the lightweight of the box,the size optimization of the box stiffeners was carried out based on the response surface method,and the optimal section size of the stiffeners was obtained.According to the optimized size,the box was designed for the second time.The analysis results show that,on the premise of meeting the use requirements,the weight of the stiffeners in the second design is reduced by 36%compared with that in the first design,which achieves the purpose of lightweight,proves the rationality and feasibility of the optimized design,and provides reference for the related design of the box body.
