Summary:

The paper presents a new computer based design method for valve plate design using the simulation program CASPAR and the extension tool AVAS. CASPAR is based on a non-isothermal gap flow model considering time dependent gap heights and surface deformations due to high pressure loads for all connected gaps of swash plate axial piston machines. Among others the program allows the prediction of oscillating forces exerted on machine parts and the calculation of effective flow pulsation on both ports as a function of design and operating parameters. Together with the calculated instantaneous cylinder pressure the flow pulsation and oscillating forces can be taken as criterion to evaluate the effectiveness of design measures for noise reduction during the design phase, id est before prototype production. The models used in the program have been verified by different measurements on pumps and motors
