[Abstract]:Because of the complex topography change in the coal mine, it is inevitable that there will be bending in the installation process of the conveyor pin rail, but the horizontal bending between the adjacent two pin rows must not exceed 鹵1 擄, and the fluctuation in the vertical direction must not exceed 鹵3 擄.In view of the limit working position under the allowable bending angle, the joint simulation of the engagement of the gear rail wheel of the traveling part of the shearer with the pin rail is carried out by using the multi-body dynamics simulation software RecurDyn and the finite element analysis software, and the rigid-flexible coupling characteristic curve is obtained.In order to obtain the correct rigid-flexible coupling characteristic curve, the following steps are carried out in this paper: 1) first, the mechanical analysis of the whole shearer is carried out, and the force condition of the walking part is obtained. 2) the meshing simulation of the pure rigid body is carried out.Get the correct meshing motion state of the traveling part and the pin rail. 3) use the finite element analysis method to select and divide the mesh of the flexible body of the gear rail wheel accurately. 4) finally, the rigid and flexible coupling between the tooth rail wheel and the drive wheel and the pin rail is carried out by RecurDyn.The combined model is simulated and simulated.The meshing velocity, acceleration and engagement force curves of the gear rail wheel with each critical angle are obtained.
