Abstract

Steering linkages play an important role in maneuvering of cars. In order to provide pure rolling of the road wheels and to reduce wear of the tires, the steering linkage must be able to turn the wheels such that their axis intersection point lies on the rear wheel axis. This condition is known as the Ackermann condition. However, in reality, Ackermann condition is difficult to satisfy for every cornering radius. The only effort we can do is to synthesize the linkage so that the Ackermann condition is satisfied for any turning radius as closely as possible. Hence, an appropriate kinematic model of the steering linkage is essential. The purpose of this research is to analyze the rack and pinion steering linkage for the ITS electric car prototype. From this analysis, the information on the steering linkage dimension and the placement of the steering linkage that give minimum steering error can be obtained. The steering error is defined as the difference between the actual angle made by the outer front wheel during steering maneuvers and the correct angle for the same wheel based on the Ackerman principle. In addition, the steady-state cornering behavior analysis is also conducted. From this analysis, the information of the center of gravity location that give better cornering characteristics can be obtained. Therefore, these analyses help and can be used as starting point to design the chassis and cabin for the ITS electric car prototype.

Abstract

The SAVGS as active low bandwidth retrofitted in the double-wishbone arrangement is studied. In this study, two configurations of arm linkages and variations of single-link are investigated. A linear equivalent model of the quarter car is presented based on energy conservation principles. The estimated results captured that the spring stiffness and damping coefficients of the equivalent model behave smaller when lengthening the lower arm geometry. On the other hand, the spring stiffness, damping coefficients, and linear actuator speed of the equivalent model increase when lengthening the single-link.

Abstract

Two-wheeled vehicle has many advantages such as small size, more efficiency, and more maneuverable. These advantages come at the lack of stability and safety. To improve the stability and safety of a two-wheeled vehicle, the Control Moment Gyroscopic Stabilization is considered. This system is composed to generate counteracting roll stabilizing torque. In this study, the system of gyroscopic stabilizer is simulated and validated to be implemented into a two-wheeled vehicle. Proportional-Integral-Derivative (PID) controller is designed to control the gimbal for generating the balancing torque. The performance of the proposed controller is evaluated through simulation for non-linear cases. The result of the non-linear model confirms a good balance in terms of rapid response.
