摘　　要：针对晶振生产中多道生产工序之间没有进行有效的对接情况,通过对这一过程实际生产需求的了解,采用Solid Works软件对晶振夹具盘传送机建立三维模型,并基于Simulation对晶振夹具盘传送机关键零件限位挡座进行了冲击仿真,得出在100 N的冲击力下其最大应力为45.1 MP,最大型变量为0.0023 mm,符合设计需求。为预防晶振传送机关键零件承重架发生共振,对其进行了模态分析,其1~6阶的固有频率为,48.21 Hz、66.906 Hz、195.85 Hz、229.22 Hz、310.91 Hz、427.4 Hz,对其1~6阶固有频率进行了分析,其中1阶固有频率接近外部激励频率,为避免承重架在受外部激励的情况下产生共振,对承重架进行了优化,其1~6阶固有频率都有一定提高,最大变形量都有一定降低。该研究可为机械结构的研发设计提供参考。In view of the fact that there is no effective docking between multiple production processes in crys-tal vibration production, through the understanding of the actual production demand of this pro-cess, Solid Works software is used to establish a three-dimensional model of the crystal vibration clamp plate conveyor, and the impact Simulation is carried out on the limit holder of the key parts of the crystal vibration clamp plate conveyor based on the simulation. It is concluded that the maximum stress is 45.1 MP and the maximum variable is 0.0023 mm under the impact force of 100 N, which meets the design requirements. In order to prevent the resonance of the bearing frame of the key part of the crystal oscillator conveyor, a modal analysis was carried out on it, and its natural frequency of order 1~6 is, 48.21 Hz, 66.906 Hz, 195.85 Hz, 229.22 Hz, 310.91 Hz, 427.4 Hz, the first order natural frequency is close to the external excitation frequency. In order to avoid resonance of the load-bearing frame under external excitation, the load-bearing frame is optimized. The 1~6 or-der natural frequency has a certain increase, and the maximum deformation has a certain decrease. The research can provide reference for the research and design of mechanical structure.
