Abstract

This paper presents a solution of the vibration reduction in driving automotive shafts. Generally, vibration modes in automotive driveshafts are divided into the bending and torsional vibrations. However, the bending vibration is more dominant factor when it excites with the resonance frequencies in automotive driveshafts. In this paper, the vibration damping structure of automotive driveshaft is introduced by incorporating piezofiber composite structure, which is also called as MFC (Macro Fiber Composite). The MFC is an innovative actuator that offers high performance and flexibility than other piezo-materials, so it is the best candidate of actuator to apply to the curved surface of shaft. In order to simulate the bending vibration reduction in the automotive shaft, analytical model based on cylindrical shell theory was developed. Moreover, Finite Element Analysis (FEA) using the piezoelectric-thermal analogy technique was conducted to confirm the analytical results and demonstrate the vibration reduction performance. The effect by the polarity of MFC on the vibration damping is also studied to find the best combination of MFC activation. Thus, the results showcase the optimal vibration damping capabilities using MFC in automotive driveshafts, and provide an outlook for the active damping control using the multi-mode resonance controllers.
