함수형 현가장치 차량동역학 모델에 의한 정상상태 해석 = Steady-State Analysis Using Functional Suspension Vehicle Dynamics Model

다국어 초록 (Multilingual Abstract)

Studies for a vehicle dynamics model including kinematic and compliance characteristics of the suspension have not been actively these days. The purpose of this paper is to determine steady-state reponses of a vehicle by using the verified functional suspension vehicle dynamics model. First section 2 will show that the differential equation of motion in the functional suspension vehicle dynamics model have 10 degrees of freedom. In the first part of section 3, it will be demonstrated that the differential equations are converted to a set of algebraic equations in the steady-state responses characteristics. Finally, in the same chapter, equations of motion will be shown to have 10 degrees of freedom and 9 variable states in terms of algebraic equations. These equations can be solved by using the Guass-Newton Method, which is one of numerical methods. In section 4, these simulation results are compared with those obtained from a transient dynamic analysis, J-Turn simulation, in order to demonstrate that they are almost the same. Section 5 will focus on the fact that steady-state analysis can be used for understanding cornering behavior results. A steady-state analysis using a functional suspension vehicle dynamics model is an effective analysis method for getting vehicle steady-state responses because it help to get vehicle data with ease and shortens the amount of computer simulation time.
