Optimization Method of VSR Process Parameters for Large Machine Tool Body
摘要
Abstract
A new method of achieving the best process parameters of VSR through modal simula-tion was proposed herein.Then the average stress elimination rate of the new process and the original process on the bed casting was compared.The experimental results show that,the average stress elimination rate of the new technology is as 65·1%,while the original process is as 38·5%.Besides, the stress value of one test point under the original process condition increases instead.The stress elimination rate of the new process is higher than that of the original process.The results verify the correctness of the optimization method of VSR process parameters for large machine tool body.关键词
