摘要

从理论分析与模型试验研究两方面探讨利用吸振器消除工业厂房框架梁横向振动的可行性。将振动设备与支撑框架梁构成的动力系统简化为弹性支座支撑的受简谐动力作用并有连续分布参数的Euler-Bernoulli梁。安装吸振器后理论分析吸收框架梁横向振动的可行性;通过对模型进行试验研究验证理论分析的可行性。结果表明,利用吸振器消除框架梁横向振动完全可行。

Abstract

The feasibility for absorbing the transverse vibration of a frame-beam induced by oscillating equipment using a vibrational absorber is studied by both theoretic and experimental approaches. Firstly, the modeling for the dynamic system composed by a piece of oscillating equipment and its supporting frame-beam is carried out, which turns to be an Euler-Bernoulli beam of distributed parameters supported elastically on its ends under the dynamic action of harmonic loading. And then a vibrational absorber is attached to the analytical model so as to theoretically analyze the feasibility for diminishing the transverse oscillation of a frame-beam induced by oscillating equipment. Finally, an experimental model is made to testify the possibility of the theoretic analysis. Both theoretic and experimental investigations show that it is feasible for diminishing the transverse vibration of a frame-beam due to oscillating equipment attached on the beam using a vibrational absorber.
