摘要:
为提高螺杆转子磨床的整体精度,合理控制成本,建立其19项空间误差模型。基于多体系统理论,结合该磨床的结构和运动特点,分析了磨床的拓扑结构。综合考虑磨床整体精度和制造成本,提出了一种精度分配优化方法。通过调整精度权数可实现不同应用需求的目标优化。结果表明:重视提高精度的优化方案较传统的经验设计值,在X/Y/Z轴方向上使机床的精度分别提高27.5%、45%和52%;重视控制成本的优化方案可降低成本25%。
Abstract:
To improve the overall accuracies of screw rotor grinding machines and reduce the costs,ninteen geometric error models are built.The topology structures of the grinder machines are analyzed based on the multibody system theory and their structures and movement characters.An optimal method of accuracy distribution is proposed according to the integrated accuracies and costs of the grinder machines.The objective optimization of different needs can be realized by adjusting the precision weights.The results show that comparing with the traditional experiential designs,the optimal scheme focusing on improving the accuracy can improve the overall accuracies in X/Y/Z axis by 27.5%,45% and 52%;the optimal scheme focusing on controlling the cost can reduce the cost by 25%.
