| Abstract |
Camshaft usually vibrates violently in swing grinding due to its complex contour, and the damping performance of device directly affects the surface quality of camshaft. Aiming at the problem that the traditional vibration damping device has been forced by installation constraints and it is difficult to control the vibration frequency in a specific range, the vibration damping structure for camshaft journal and grinder tailstock based on the local resonance bandgap (LRBG) mechanism is carried out in this paper, respectively. On the basis of the vibration data obtained from the experimental analysis, the corresponding finite element model is established, the resonant bandgap characteristics and the bandgap influence rules of each system structure are discussed. Comparing the damping performance of the system before and after vibration reduction based on the optimized vibration reduction model obtained from the influence rules, the vibration reduction effect of the local resonance (LR) structure designed in this paper is very significant. Compared with the homogeneous structure, the damping performance at the journal and tailstock is improved by 31.6% and 89.3% respectively. The design achieves the goal that controlling large wavelength with small size, which provides a good application prospect for the local resonance phononic crystals (LRPCs) in the vibration reduction field of camshaft swing grinding. |
