TBM刀盘缩尺试验台设计及其静动态特性分析
Design of a TBM cutterhead reduced-scale test bench and its static/dynamic characteristics analysis
摘要
Abstract
The diameter of a real cutterhead is so large (≥6 m) that experiments on a life⁃sized cutterhead would in⁃volve significant costs and would be difficult to conduct. Therefore, research on a reduced⁃scale model of a tunnel⁃boring machine ( TBM) cutterhead is beneficial to the optimization and life⁃extension design of the tool. A collection of parameters such as material, geometry, load, and dynamic quantities of a TBM cutterhead were gathered. Based on the theory of similarity. The design parameters of the test bench were acquired, and a reduced⁃scale test bench for a TBM cutterhead with different assembly structures and different cutter⁃knife arrangements was designed based on the parameters and load characteristics of the multi⁃point impact distribution determined from the excavation process of an actual TBM cutter. The static and dynamic analyses of the test bench were performed with AnsysWorkbench and AD⁃AMS software. The results show that, compared to the expected value, the stiffness and damping error of the reduced⁃scale cutterhead is less than 5.3%, the mean value error is less than 4.2% and the variance error is less than 2.9%, proving the similarity of the test model's static and dynamic performance to the performance of an actual cutterhead.关键词
