MODEL-BASED SIMULATION OF A HYDRAULIC OPEN-LOOP ROTARY TRANSMISSION WITH AUTOMATIC REGULATION OF HYDRAULIC MOTOR (PART 1: MODELLING)

摘要

Model-based simulation of a hydraulic open-loop rotary transmission with automatic regulation of hydraulic motor is considered in the paper. The approach is based on multi-pole modelling and intelligent simulation. In Part 1 of the paper the functional scheme of the transmission is described and corresponding multi-pole model is introduced. Mathematical multi-pole models of functional elements for stationary conditions and for dynamic transient responses are presented. In Part 2 of the paper simulation of steady-state conditions and dynamic responses of the hydraulic transmission is considered. A high-level graphical environment CoCoVila (compiler compiler for visual languages) is used as a tool for describing models and performing simulations. Object-oriented multi-pole models, visual programming environment, automatic program synthesis and distributed computing are as original approach in simulation of fluid power systems.
