基于钢轨实测廓形的智能打磨策略
Intelligent Grinding Strategy Based on Rail Measured Profile
摘要
Abstract
The existing rail grinding strategy has such problems as uncontrollable grinding results and depending too much on human experiences for setting grinding parameters.An intelligent grinding strategy based on rail measured profile is proposed.Firstly,the target rail profile is determined according to rail measured profile.Then,the threshold of the finished grinding is obtained according to the difference between the measured profile and target profile.The working speed and power of grinding car are calculated based on triangular area method and the work capacity of single grinding wheel.The point where the difference between the measured profile and target profile is the maximum is located.The deflection angle of grinding wheel needed for grinding the point is calculated,and then a new profile is obtained after grinding the measured profile by single grinding wheel with fixed power.The new profile is compared with target profile,and the point where the difference between the new profile and target profile is the maximum is located.If the maximum difference of the point is less than the threshold,the grinding is stopped.Otherwise the above process is repeated until the maximum difference between the new profile and the target profile is less than the threshold.Accordingly,the deflection angle of each grinding wheel needed for grinding the measured profile to the target profile is obtained and the grinding scheme is formed.The effectiveness of the intelligent grinding strategy based on the measured profile of rail is verified by experiment.关键词
