摘要 | A single bolt connection cantilever model is used to analyze the difference of vibrational property due to bolt-joint which is widely used in optoelectronic devices. The phenomenon of super-harmonic resonance due to bolt joint connection is verified using the shaker experiment combined with the signal acquisition equipment. In the case that the torque incerease, the resonance frequency of the model increase first and then decrease. The first resonance frequency decrease when the excitation amplitude decrease and the nonlinear structure characteristic is soft nonlinear. The energy inclined to the natural frequency when the excitation amplitude become large while the system excited under the sinusoidal 1/2 and 1/3 times the resonant frequency. When the system is under low pretension, quadratic nonlinear terms in the structural response plays the major role; while at higher pretension, cubic nonlinear term in nonlinear terms of the structural response plays the major role. The results about research has some theoretical and guidance about subsequent nonlinear vibration characteristic calculation. 2017, Science Press. All right reserved. |
