用广义有限元方法建立弹性连杆机构振动分析模型,首次提出了频率几率的概念。运用此概念,结合共振理论可以较完满地解释弹性连杆机构的低阶谐振现象。
By using the generalized finite element method to establish the vibration analysis model of elastic linkage, the concept of frequency probability is proposed for the first time. Using this concept, combined with the resonance theory can be more satisfactorily explain the lower-order resonance phenomenon of the elastic linkage mechanism.
