Abstract

The titanium alloy brake shell is an important component used in aviation, but its surface polishing is mostly done manually, making it difficult to ensure surface quality and consistency. As a result, an industrial robot polishing system based on digital twin is proposed, which can realize the interaction between physical and virtual platforms by using digital twin technology, acquire various parameters in real time, and monitor the polishing process. Based on this system, a removal depth model was established, and the polishing parameters to be analyzed were determined by combining the removal depth model. On this basis, the influence law of polishing parameters on surface roughness is analyzed through physical tests, and orthogonal experiments are used to optimize the polishing parameters. The results show that the surface roughness is reduced to 0.171 μm after optimization. Finally, the reliability of the polishing system is verified through the polishing machining test, and the surface quality of titanium alloy brake shell is significantly improved.

基于数字双胞胎的工业机器人抛光钛合金制动器壳体的表面性能

钛合金刹车壳是航空领域使用的重要部件，但其表面抛光多由人工完成，难以保证表面质量和一致性。因此，本文提出了一种基于数字孪生的工业机器人抛光系统，利用数字孪生技术实现物理平台与虚拟平台的交互，实时获取各种参数，监控抛光过程。基于该系统，建立了去除深度模型，并结合去除深度模型确定了待分析的抛光参数。在此基础上，通过物理试验分析抛光参数对表面粗糙度的影响规律，并采用正交实验对抛光参数进行优化。结果表明，优化后表面粗糙度降至 0.171 μm。最后，通过抛光加工试验验证了抛光系统的可靠性，钛合金制动器壳体的表面质量得到明显改善。
