The Dynamic Characteristics of Hydraulic-Mechanical Constant Speed Drive

Abstract

Annotation This paper discusses the development of a mathematical model for the constant speed drive, comprising the power supply of an aircraft power grid. The model is developed in the form of equations of dynamics of the drive main components, such as differential, volumetric hydraulic transmission, centrifugal regulator, auxiliary pumps, as well as using the AMESim calculation package. The model has been verified using experimental data of the AC frequency responses of the existing unit to various influences. The models obtained allow to conclude about the stability of the system, and to optimize the control system parameters.
