Computational Valve Plate Design in Axial Piston Pumps/Motors
Hollywood, California, USA. October 12—14, This study is a part of a larger research project to predict noise sources of hydrostatic transmissions and investigating new methods for designing quieter systems. The aim of this study is to validate the developed model describing pump dynamics coupled with effects of a connecting line, thus validating a coupled pump-motor-line model for hydrostatic transmissions. This paper illustrates a numerical approach for evaluating pressure and flow oscillations generated by a hydraulic pump coupled with a connecting line. The presented model describes pump dynamics using a lumped parameter approach as well as one-dimensional unsteady compressible fluid flow by means of method of characteristics MOC.

Sponsor: Confidential 3. Statement of Project Goals The goal of this project is to help transform the design of hydraulic pumps and motors from a cumbersome task, requiring significant trial-and-error testing, to a modern approach driven by numerical simulation and digital prototyping. Previous research has developed a fluid-structure-thermal simulation model which is capable of predicting the performance of critical lubricating interfaces inside axial piston machines. The key area of this research is to utilize the latest virtual prototyping and optimization techniques in practical pump design. Improve unit efficiency by reducing the energy dissipation 2.

These new technologies allow major fuel savings and reduced emissions, but they change the performance requirements of positive displacement pumps and motors. Additionally, the market demand for positive displacement machines will increase. This paper briefly discusses these technology trends and the impact on existing pump and motor designs. The three major challenges are efficiency improvements, noise reduction and advancements in pump and motor control.
Huhtala discussed the strength and weakness of some existing models for hydraulic piston machines and unfortunately concluded that any model is not accurate enough for wide operating ranges. As an effort to develop an accurate model applicable for wide operating range, Jeong proposed a performance coefficient model for a hydraulic axial piston motor of swash plate design, which is given by the physical dimensions. In this paper, validity of the new performance model is addressed through experimental analysis. Estimation process for model parameters is established and then performance decision parameters are estimated from efficiency measurement data for a test motor.
For all axial piston machines,the valve plate functions as an essential determinant of performance. Theaim of this research is to develop a design methodology generalizable to alltypes of valve plates while remaining accessible to users without advancedtechnical knowledge. The proposed design methodology is organized to fit theform of the standardized optimization problem statement. This organizationenables the use of any modern optimization algorithm. Specifically, the designmethodology utilizes a previously developed computer model, which is basedon the main physical phenomena influencing the design of flow passagesfrom the pump port to the displacement chambers and vice versa.
