The Roadheader Auto-Rectification Dynamic Analysis and ...

2021-01-03  Dynamic Modeling of Roadheader. There is lateral resistance on the roadheader track during the rectification. Considering the complicated road conditions in the roadway, the actual track end of the rectification process has a stronger squeezing effect on the pavement soil than other positions during the rectification. The distance away from the track instantaneous velocity center is smaller ...
