摘　　要：以高速压片机为研究对象,利用Pro/e建立压片机的三维几何模型,利用ANSYS前处理建立压片机有限元模型。对结构进行了模态分析和谐响应分析,得到了机器的固有频率和振型,以及在谐波激励作用下的稳态响应。对整体结构进行力的优化,有效的抑制了共振现象的发生,解决了压片机工作时的振动和噪音问题。分析结果对压片机的设计提供了很实用的理论参考价值。The high rate tabletmachine is the subject investigated. The three-dimensional geometric model is established by Pro/e, and the three-dimensional finite element model is established by fore treatment of ANSYS. The harmonic analysis is executed, and the corresponding response is gained under the harmonic force.oThe force that the machine is received is optimized and the result is the resonance is restrained effectively. In addition, the problem of the vibration and noise is resolved. All the result is very useful for the design of the tcdetmachine.
