Abstract
 The application of intelligent materials in traditional engineering structures gives intelligent features such as adaptive adjustment, self-diagnosis and self-repair of traditional structures. In addition, it will enhance structural strength and improve structural performance. Its various characteristics and application prospects are broad. Become a research hotspot in various countries. With the development of the manufacturing industry, the automotive industry is also taking off at high speed, and people put forward higher requirements for the comfort, safety and operational stability of the car during driving. The car suspension system is the main system of chassis control, but the traditional suspension system often has the contradiction of improving the single performance and discarding another performance requirement. Therefore, it is a hot spot to solve the contradiction and make up the defects by combining the development of smart materials. The intelligent material-based adaptive suspension has become the research and development object of its low energy consumption, adaptive control, stable safety and effective improvement of vehicle performance. For example, a damper based on a smart material magnetorheological fluid has the advantages of faster response, continuously adjustable damping force, and ease of integration with digital computer technology compared to conventional dampers.
