一种强迫激励下的弦线模型振动分析与求解.

In order to research the conveyor belt vibration law during the working process under the random load, the random forced vibration model of the conveyor belt is established by using the forced string theory. The initial mathematical boundary conditions of the conveyor belt is derived, and the forced stimulus resulted from eccentric condition of the conveyor belt rollers on the both sides and the vertical load stimulus resulted from the random distribution of the materials on the conveyor belt are established. The model analytical solution is derived by employing the superposition principle and the separation of variables. Finally, the numerical analysis of the vibration characteristics of the conveyor belt is performed, and the validity of the model analytical solution is validated by the analysis results. The research results provide the basis for the dynamic reliability design of the conveyor belt. [ABSTRACT FROM AUTHOR]
