摘要:

利用Dynaform有限元软件对某离合器盖总成传动带的成形回弹过程进行数值模拟,分析了传动带回弹前与回弹后的应力分布,传动带回弹前与回弹后圆角处的最大应力值分别为871.805和339.947 MPa,应力值的减小使得板料发生回弹。研究了弯曲角度、板料厚度及模具间隙对传动带成形高度的影响。结果表明:传动带的成形高度随着弯曲角度及模具间隙的增大而逐渐增加,而随着板料厚度的增加呈现逐渐减小的趋势。此外,设计传动带成形模进行实验验证,成形高度的实验值与模拟值的误差为7.55%~9.18%,吻合性较好。其中模具间隙为1.1t时,成形高度的实验值为4.98 mm,符合产品的设计要求4.9~5.45 mm,且实验值与模拟值的误差为8.84%。

The springback process of forming for transmission belt of clutch was simulated by Dynaform, the distributions of stress before and after spingback were analyzed, and the maximum stress values at round corner before and after spingback were 871.805 MPa and 339.947 MPa respectively, so the reduction of stress resulted in the blank springback. The influence of bending angle, thickness of blank and die clearance on forming height of transmission belt was studied. The results show that forming height of transmission belt increases with the increase of bending angle and die clearance, while decreases with the increase of thickness. Additionally, forming die of transmission belt was designed and verified by the experiment, the range of error between experiment and simulation is 7.55%-9.18%,which shows good agreement. When the die clearance is 1.1t, the experimental value of forming height is 4.98 mm, which meets the design requirement of 4.9-5.45 mm, and the error between experiment and simulation is 8.84%.
