单磨头打磨钢轨廓形的仿真分析
Simulation Analysis of the Rail Profile after Grinding by Single Grinding Wheel
摘要
Abstract
Rail grinding is an important means for railway maintenance, and only grinding with high precision can further prolong the service life of rail. Hence, it is significant to research the rail profile after grinding for improving the grinding accuracy. This paper, taking the PGM-96C grinding car as an example, proposed a grind ing quantity calculation method of single grinding wheel, then verified the calculation method by field test, and finally made the simulation analysis of rail profiles in different grinding angles. Results show: when the grinding power is 17.6 kW and the angle of grinding wheel 0°, the grinding depth is 0.08 mm and the grinding width is 12.17 mm;with the increase of the angle, the grinding depth is also increasing, but the grinding width is decreasing; when the angle of grinding wheel is more than 20° , the grinding depth remains around 0.22 mm with the grinding width around 4.70 mm.关键词
