Application of HIL Technologies in Developing an Algorithm for Suppressing Longitudinal and Angular Vibrations of a Mining Dump Truck

Abstract

The paper considers the use of HIL technology for testing and debugging the algorithm for damping longitudinal ad angular vibrations of a mining dump truck. Using a computer dynamic model of the mining dump truck, the proposed algorithm for damping longitudinal and angular vibrations has been tested for cases of movement on roads with different characteristics of the micro-profile. The efficiency of functioning of the developed algorithm of longitudinal and angular oscillations and the possibility of reducing the oscillation amplitude in the dump truck cabin by 20 % have been confirmed. A semi-natural bench has been formed for testing and debugging the software of the longitudinal and angular vibration damping system. For the on-board controller of the dump truck, software has been developed that implements the control of the brake system according to the proposed algorithm for damping longitudinal and angular vibrations.
