摘要
主梁作为拉伸机的主要承载组件,其结构合理性直接影响到整机工作性能和玻璃质量,为减小应力与受力变形,对主梁进行有限元分析并进行优化设计。在受力分析的基础上,设计主梁结构,并进行结构强度与变形分析。根据有限元分析结果,强化主梁与丝杠连接处外侧的薄弱部位。经过HyperOpt优化设计得到主梁宽度和拉力中心距的最优数值。单侧承受900 kN拉力的工况下,主梁最大变形由3 mm降低到小于1.5 mm,最大应力由352 Mpa降低到190 Mpa。
The main beam is the load-bearing part of the stretching machine,and its structural rationality directly affects the performance of the whole machine and the quality of the glass.In order to reduce stress and deformation,the main beam was subjected to finite element analysis and optimized design.Based on the force analysis,the main beam structure was designed,and the structure strength and deformation analysis were performed.According to the results of finite element analysis,the weak parts on the outside of the connection were strengthened between the main beam and the screw.The optimal value of the main beam width and the center distance of the tension was obtained using HyperOpt optimization.Under 900 kN pulling force condition,the deformation of the main beam reduced from 3 mm to less than 1.5 mm,and the stress was reduced from 352 MPa to 190 MPa.
