Abstract

The invention discloses an experimental device for an electronic power optimizing control system of an excavator. The device is used for the technical training of construction unit, excavator production factory and school or the practice teaching of correlated curriculum. The experimental device consists of an element object of an electronic power optimizing control system and a sensor signal analog device or unit. The electronic power optimizing control system element realizes the simulation according to the actual circuit connection, the working state of an engine, the rotating speed of an engine, the oil pressure of a pump, cooled water temperature and the outputs of other switching value sensors. The experimental device simulates the work of the electronic power optimizing control system of the excavator without an engine or a hydraulic system object by simulating the outputs of various types of sensors under different working conditions of the excavator.

Description
