摘　　要：针对螺旋式速冻机的转鼓系统的复杂性,根据转鼓系统的工况条件,分析了转鼓的受力特点,建立了转鼓系统的分布式径向力计算模型,采用ANSYS软件对速冻机转鼓进行了静力学分析,得到了转鼓系统应力和变形的分布规律,并进行了强度校核。最后,在保证结构可靠性的前提下,通过改变转鼓内部方管的数量和支环尺寸,经反复建模验算后,得到了最终的优化结构。仿真结果表明:该优化方案能够有效满足速冻机转鼓结构轻量化的要求,可用于指导生产实际,同时为同类结构的设计优化提供了依据。For the complexity of the spiral freezer drum system, the distributed ctdculation of razlitd farce of the drum system is established according to the working condition and the characteristics of the stress of the drum .Then it applies the static analysis to the spiral freezer drum with ANSYS software, and the displacement and stress distribution law of the drum are got. At last, based on modeling and repeatedly verifying, the final optimal structure is obtained by changing the qutmtity of the square tube in the drum attd the ring size under the premise of ensuring the structural reliability. The simulation result shows that this optimization scheme effectively meet the lightweight requirements of the structure of the spiral freezer drum and be used to guide the actual production, providing basis for the design and optimization of similar structure.
