차량동력학 해석을 위한 조향장치의 모델링

In this study, a modeling method of power-assisted steering systems for vehicle dynamic analysis is presented. Pressure-flow relations of flow control valve is derived, and the equations of motion of a steering gear is obtained. Combining pressure-flow relations and equations of motion. the steering force can be represented as a function of steering wheel angle or torque. For complete representation a steering system, a steering linkage of a truck is modeled based on the multi body method.
