Research on Residual Stress Ding Tao Measurement of Railway Wheel
摘要
Abstract
With the help of simulation analysis method, the change laws of saw kerf width and stress/strain near the kerf were studied when radial saw cutting. The analyses show that when the saw cutting depth reaches the joint of rim and plate, the release of residual stress is sufficient enough to calculate the residual stress on the tread based on release information of residual stress. On the basis of the radial saw cutting method, strain gauges were pasted near the kerf and record the strain change when saw cutting. The residual stress was calculated according to the strain change information.关键词
