摘　　要：大型船用曲轴的重量及体积庞大,磨削精度要求很高,而曲轴磨床刚度对磨削精度影响很大,因此,能够仿真解析和改善磨床的刚度尤为重要。基于Pro/E的子模块——Pro/MECHANICA有限元分析软件,建立了大型曲轴磨床整体模型,并对磨床进行了静态刚度计算及优化设计,最终得到了既能够减轻磨床质量,降低生产成本,又能够改善磨床刚度,提高加工精度的优化结果。从而为提高大型曲轴磨床的加工精度,获得更佳设计方案提出了思路。The large-scale ship crankshaft has very high grinding accuracy requirement, and the grinding accuracy is influenced by the rigidity of crankshaft grinding machine. So it is very important to simulate and improve the rigidity of the grinding machine. Using finite element analysis software Pro/MECHANICA of Pro/E, the three dimensional model of large-scale ship crankshaft grinding machine was constructed, the rigidity of the grinding machine was predicted and the structure was optimized. The optimization results to lighten the grinding machine and reduces the costs of production, but also improves the rigidity and the processing accuracy of the grinding machine. The better design proposal of the large-scale ship crankshaft grinding machine is provided.
