DYNAMIC RESPONSE OF PIPING SYSTEMS DUE TO MOVING LOAD

Abstract cze:
Abstrakt: In all power plants (classical and nuclear) are used safety relief valves. After opening of this ones the mass of fluid (gas or steam) begin to move with very high velocity and induce dynamic stresses in piping linked to the valve. The solution of this problem consist of three stages: arival of the load, moving strip of the load and departure of the load. All this ones are shortly discused on the basis of equation of motion and its solution in analytical form. The recommendations for practical applications are formulated.
