swing valve for coal roadheader

Multifactor Analysis of Roadheader''s Body Pose Responses

Based on the Lagrange equation in system dynamics, aiming at the horizontal cutting process, the dynamical coupling model of boomtype roadheader''s body pose was established. According to input problem of solving the model, a calculation method of the cutting head load was proposed, and the relationship between the cutting head load and pressure of the driving cylinders and swing angle of
