| Abstract: | In this paper, the optimum design of a large flow relefvalve for hydraulic roof supports has been mabe for the damage caused to hydraulic roof supports by dynamic load in the coalfacs. A dynamic equation and a mathematical model of optimization have been established for a large flow relief valve with back gas spring, poppet and diffential construction. A complex method and BASIC language are used to work out a versatile optimum program for the design of the relief valve for hydraulic roof supports. The optimum parameters are calculated for a large flow relief valve with 10000L/min. Finally, the model test and the computer simulation are made for the large flow relief valve |
