摘要
用摄动分析方法,从组合共振的角度,就弹性机构低阶谐振响应不完全同步的机理进行了研究。发现由几何非线性引起的平方非线性环节、内共振和机构运动惯性力的多频分力共同引起的组合并振,是导致连杆、摇杆低阶谐振现象不完全同步的原因。
The method of multiple scales is adopted to investigate the combination reco-namces elastic linkages under the inertial forces.The analyses have demonstated thatthe combination resonances caused by the internal resonance in the form of ,thecubic nonlinearities due to large elastic deformation of flexible links,and multi-frequenciesof the inertial forces of linkages are the reason to lead to nonsynchronism of lower orderharmonic resonances of elastic linkages.
