Abstract:

A test-board of microcomputer-operated hydraulic excavator with bucket is developed. Its power is 7.5 KW and working pressure is 14MPa. The technique of electrohydraulic proportional servo and two-level computer control is applied. The operation of task process of excavator with microcomputer is to make pose of bucket approach trajectory obtained with the aid of planning. The methods of path and trajectory planning in view of high effect are further presented. The relevant control software is developed and the control of desired task process is realized at the test-board.
