TBM盘形滚刀磨损预测模型
A wear prediction model of disc cutter for TBM
摘要
Abstract
In order to study the wear behavior of tunnel boring machine (TBM) disc cutters during the process of rock breaking,kinematic formulas of constant-section disc cutter were established through the analysis of motion characteristics between cutter head and disc cutter.The wear prediction model of disc cutter,which was programmed in MATLAB,was built by combining theory of abrasive wear and cutter-rock contact mechanics.The model was applied to simulate the wear process of cutters in a water diversion project.The evolution laws of wear morphology of disc cutters were obtained.The results show that the simulated wear quantity and the measured wear amount are consistent with the changing tendency of the tool position number,and the average relative errors of normal and lateral face wear of the disc cutters are 18％ and 30％,respectively.The cutter ring gradually wears to be tip-shaped,which coincided with the actual wear form.关键词
