Abstract
The influence of different constraint conditions on the high-frequency vibration performance of viscoelastic materials is studied. The coherences between the different constraint conditions and the vibration properties of a damping beam are compared by transfer function method in 2 000 Hz-6 000 Hz frequency range. Vibration damping tests under different constraint conditions of the beam are simulated by the finite element method. The simulation results of the speed transfer rates at the intermediate nodes of the most formants are compared with those of the experiments. It shows that the simulation result is closer to the test result for the damping beam with both ends clamped than that for the damping beam with only one end clamped. This work provides a reference for selection of constraint conditions in the high-frequency vibration tests of rubber vibrating beams.关键词
