COMPUTER PROGRAM FOR CALCULATING THE RESPONSE OF A PIPING NETWORK TO A SINUSOIDAL EXCITATION

Dynamic behavior plays an important role in the design of pneumatic control lines and propellant feedlines. Dynamic behaviour can be divided into three categories, with each category requiring a different method of treatment. These categories are: 1) quasi-steady flow, with slowly varying quantities; 2) periodic oscillations, important in stability analysis or hydraulic pump ripple problems; and 3) rapid, nonperiodic variations, such as those caused by the opening and closing of valves. Each of these categories can be further divided into cases where piping motion is negligible, and cases where it must be accounted for. This memorandum describes a method and computer program for computing the response of a complex system to a sinusiodal disturbance where piping motion is negligible or needs to be accounted for at only a small number of points.
