摘要:

以立式轧环机传动系统为对象,建立了有限元分析的实体模型。应用ANSYS/LS-DYNA分析了传动系统在极限工况下的应力随时间分布变化情况,结果表明,轴叉头的尖角处应力较大,中间球体的应力呈中心对称分布。应用ANSYS优化设计模块和参数化程序语言APDL对输入轴进行了优化设计,使其质量减小31.3%,应力下降57.9%,刚度提高40.37%。分析结果为立式轧环机传动系统的设计制造和应用提供了技术依据。

Abstract:

According to actual circumstance of the vertical ring rolling mill’s transmission system, a 3D model was established, ANSYS/LS-DYNA was used to analyze transmission system’s stress-time changing situation under extreme working conditions. The result shows the stress is large at the sharp corner of fork joint, the stress of mid sphere is centrosymmetric. The input shaft was optimized by OPT and ANSYS parametric design language APDL, and its mass is reduced by 31.3%, the stress is declined by 57.9%, the stiffness is increased by 40.37%.The result provides sufficient basis for design, production and application of the vertical ring rolling mill’s transmission system.

Key words: vertical ring rolling mill, ring-and-trunnion universal joint, mechanics research, LS-DYNA, optimal design
