With the development of economy, the progress of science and technology, the development of automobile industry is more and more rapid. There are more and more kinds of automobiles in the world. Therefore, people have higher and higher requirements for automobile performance, comfort and smoothness. Therefore, this paper makes a series of research on the design and development of continuously adjustable damping test-bed. Firstly, this paper presents the principle and classification of continuously adjustable damping damper, because the traditional passive suspension structure and damping value cannot be changed once determined, and cannot meet the requirements of various road conditions. In order to meet the complex and changeable working environment, a continuously adjustable damping damper is designed. Secondly, this paper studies half of the active suspension, and half of the active suspension includes linear model and bilinear model, and designs a scale-up quarter car test-bed. The core components of the test-bed are MR damper and tuned mass damper. Finally, the results show that the MR damper has good damping dissipation energy characteristics, and the damping value of MR damper has a good linear relationship with the current.
