Use of spatially distributed damper systems in a machine tool

在机床中使用空间分布式阻尼系统

基本信息

项目摘要

The dynamic behavior is a deciding factor in modern high-performance machine tools. Mainly for existing machines, passive dynamic auxiliary systems like tuned mass dampers can be used to improve the dynamic compliance by damping specific vibration modes. The advantage of passive systems over active ones is the possibility of a low-cost retrofit due to simple designs and low subsequent costs. Disadvantages include the substantial local mounting space requirements, the iterative and time-consuming commissioning and the vulnerability towards changes in the structural dynamics of the base system.During the first funding period of the preceding research project "Optimal positioning and tuning of multi-mass dampers within a combined topology optimization method", which generated the foundation for this knowledge transfer project, an automated optimal positioning and new analytic tuning method for multi-mass dampers was developed and experimentally verified. By dividing the auxiliary mass over many individually and mutually tuned masses and by spatially distributing them over the structure, the above-mentioned drawbacks of tuned mass dampers shall be alleviated. The effectivity and benefits of multi-mass dampers were successfully verified in a laboratory environment.The goal of this transfer project is to synthesize the gained insights and concepts that were created under academic testing conditions into a product that is suitable for industrial use and which can be tested under operating conditions. Thus, valuable knowledge and insights for further development of the optimal tuning and positioning, especially regarding the process stability, can be fed back into future research.
动态行为是现代高性能机床的决定因素。主要针对现有机器,可使用调谐质量阻尼器等被动动态辅助系统,通过阻尼特定振动模式来提高动态柔顺性。无源系统相对于有源系统的优势在于,由于设计简单且后续成本低,因此可以进行低成本改造。缺点包括大量的本地安装空间需求、迭代且耗时的调试以及基础系统结构动力学变化的脆弱性。在之前的研究项目“组合拓扑优化方法中多质量阻尼器的优化定位和调谐”的第一个资助期间,该研究项目为该知识转移项目奠定了基础,为多质量自动优化定位和新的分析调谐方法奠定了基础 开发了阻尼器并进行了实验验证。通过将辅助质量划分为许多单独且相互调谐的质量并且通过将它们在空间上分布在结构上,将减轻调谐质量阻尼器的上述缺点。多质量阻尼器的有效性和优点在实验室环境中得到了成功验证。该转移项目的目标是将在学术测试条件下获得的见解和概念综合到适合工业用途且可以在操作条件下进行测试的产品中。因此,对于进一步开发最佳调整和定位,特别是在过程稳定性方面,有价值的知识和见解可以反馈到未来的研究中。
