Abstract
The present paper describes a newly developed method of computing the losses and efficiencies of hydrostatic power converters. Unlike previous methods this approach is not based on a physical/technical analysis of a single hydraulic pump or motor type.
Instead, it employs purely mathematical methods based on measurement data to provide a universally applicable method for computing the power and efficiency behavior of hydrostatic machinery of any design. The accuracy of the method is confirmed by a comparison of measured and calculated performance and efficiency data.
