【Abstract】 After proposing an idea about a new design of powered support base on parallel mechanism,we design the control system of its powered prop,analyze operating procedure of powered prop and give an example for computing the displacement and the force.It shows that the parallel support can adapt the roof and the law of the mine pressure and assure the setting pressure of support.更多还原
