摘　　要：TMS型三电机自同步振动筛,是一种新型振动筛。为了确定TMS型振动筛筛箱的应力分布规律,保证筛箱具有足够的强度,采用Pro/mechanica建立了筛箱的计算有限元模型。进行了强度分析,同时对筛箱进行了动态特性分析,并计算出筛箱前15阶固有频率和振动模态。分析结果表明,筛箱应力集中主要出现在电机座板的连接部位,以及L型梁与筛箱侧板的连接部位,筛箱整体满足强度要求。A new type of shale shaker is put forward, which excited by three motor self-synchronously. For confirming the stress peculiarity of TMS mode three motor self-synchronism shale shaker, ensuring the strength of the shaker body, the Finite Element model for strength calculating of the shaker body was built. At the same time, the dynamic prosperities are reached and the natural frequencies and the model shapes of the shaker are calculated. Analysis results indicate, the stress centralization of the shake body appears in the connection of the motors and flat board mainly, and the connection of the L-beam and the side of board, the stress of the whole shaker body satisfies with the intensity demand.
