Automatically calculating method of simulated adjustment in the bench mark rail of non-ballasted track
摘要
Abstract
The most notable feature of high-speed railway non-ballasted track is the better smoothness.It is nec-essary to check the smoothness occasionally for the newly-built or operational high-speed railway non-ballasted track.If the smoothness of high-speed railway does not meet specification requirements,the track needs adjusting to meet the needs of safe driving.At present,the calculation for Simulated Adjustment of high-speed railway non-ballasted track is one by one manually,which has a low efficiency and a huge workload.The quality of adjusted track is also directly related to the inside worker.Therefore,how to calculate the adjustment of non-ballasted track in a fast and automatic way is a problem to be solved urgently.According to the original track off-set of non-ballasted baseline track,the adjustment of the plane and vertical track was automatically calculated with the method of polynomial fitting iteration.Through specific analysis of experiments,it proved the method of automatically calculating the adjustment of the non-ballasted track can meet the specification requirements.关键词
