Modeling, Simulation, and Analysis of Auto Warming Up and Overheat Prevention System in Komatsu Hydraulic Excavator PC 200-8

Abstract

Komatsu PC 200-8 hydraulic excavator is one of the most popular heavy equipment machine models, widely used in general sectors: construction, agriculture, and plantation. This excavator is equipped with electrical system, hydraulic system, and mechatronic system. All actuator movement in this excavator are controlled by mechatronic system. High skilled mechanics are needed to maintain the mechatronic system in this excavator. Good training method is needed to produce a skillful mechanic. The training method is conducted by theoretical introduction of the mechatronic system and followed by practice in laboratories, workshops, as well as in the field. In this project, mechatronic system simulator for Komatsu hydraulic excavator is developed to simulate auto warming up and overheat prevention system for the training purpose. The simulator has been tested in training and based on interviews with trainees, the simulator can help the learning process in the training and improve trainee knowledge and understand to operate and maintain the control system on hydraulic excavator.
