Abstract
Research and/or Engineering Questions/Objective
The suspension system plays a major role for Automotive Performance. In this paper, variable height suspension, which aims to make the same car at high speeds, reducing the suspension height, improving driving stability; and when uneven roads, raised suspension height, let the car pass. And it can combine the off-road vehicles with sports cars perfectly, and improve technology for amphibious car later.
Methodology
In order to improve the accuracy of system analysis, using a flexible body. Use vehicle simulation in the front and rear suspension to validate steering stability. The vehicle model experiment on the four pillars test to validate ride comfort and analysis the impact of vibration in the process of moving, Variable height suspension system of K & C characteristics test, Validate the reliability of theoretical approaches of the suspension system. With the development of automotive electronics technology, the suspension model by ADAMS / CAR collaborative simulation with simulink to achieve suspension height changes automatically and meet cars with adaptive changes in different conditions. With the suspension height change, it will affect the steering system, it could change with the suspension height not produce interference phenomenon through the research of steering system.
Results
Based on suspension main parameters, vehicle performance and ride comfort analysis, Through a flexible body alternative to rigid body so that the simulation results with the real situation more approximation of Automotive suspension. the suspension model by ADAMS / CAR collaborative simulation with simulink to achieve suspension height changes automatically. According to the simulation curve, summary suspension height changes to the impact of automobile suspension performance.
Limitations of this study
How to make suspension achieve variable points continuously is one of difficult problems in this study.
What does the paper offer that is new in the field including in comparison to other work by the authors?
Through flexible body alternative to rigid body so that the simulation results with the real situation more approximation of Automotive suspension. the suspension model by ADAMS / CAR collaborative simulation with simulink to achieve suspension height changes automatically and meet cars with adaptive changes in different conditions.
Conclusions
Performance by the suspension, the change of the main arguments which reflects the different suspension height. suspension model by ADAMS / CAR collaborative simulation with simulink to achieve suspension height changes automatically. With the suspension height change, it will affect the steering system, it could change with the suspension height not produce interference phenomenon through the research of steering system.
