Abstract

This article presents an active safety system for a wheeled armored vehicle to encounter the effect of the firing force. The firing force which acts as an external disturbance causes unwanted yaw moment occurred at the center of gravity of the wheeled armored vehicle. This effect causes the wheeled armored vehicle lose its handling stability and the traveling path after the firing condition. In order to overcome the stability problem, a Firing-On-the-Move assisted by an Active Front Wheel Steering system is proposed in this study. This system is developed based on two established systems, namely, Firing-On-the-Move and Active Front Wheel Steering systems. The proposed system is designed to improve the handling and directional stability performances of the armored vehicle while fires in dynamic condition. Four types of control strategies are designed and investigated in this study to identify the most optimum control strategy as the Firing-On-the-Move assisted by an Active Front Wheel Steering system using optimization tool, genetic algorithm. The control strategies for the Firing-On-the-Move assisted by an Active Front Wheel Steering are evaluated using various types of vehicle speeds and firing angle in order to obtain an appropriate control structure as the Firing-On-the-Move assisted by an Active Front Wheel Steering system for the wheeled armored vehicle.

Highlights

Armored fighting vehicle is used as one of the important defensive systems in the military application.[1]. This type of vehicle is designed using strong extensive armor which acts as a shell to protect the infantry during combats
The armored vehicle is equipped with a gun turret system for a counter-attack against the enemy.[1,2]
Based on the evaluation above, it can be concluded that all four cases show better performances on the 17 DOFs of armored vehicle

Summary

Introduction

Armored fighting vehicle is used as one of the important defensive systems in the military application.[1]. Where Fzfl, Fzfr, Fzrl, and Fzrr are the normal forces; Fdfl, Fdfr, Fdrl, and Fdrr are the damper forces; Fsfl, Fsfr, Fsrl, and Fsrr are the spring forces acting in the vertical direction of the armored vehicle. The estimated lateral force is used as second feedback in the outer loop control to maintain the directional path of the armored vehicle.
