摘要：

分析钢丝帘布裁断机裁剪过程中上机架的受力情况，对其进行静力学仿真，得出了裁剪的帘布产生毛刺的主要原因为：安装裁刀部分在z轴方向上过大的形变量使得裁剪间隙增加过多，导致裁剪的帘布中间部分有毛刺，并得出了上机架z轴方向的许用形变量为0.020 mm。对上机架进行模态分析，验证了其振动的可靠性。为了解决毛刺问题，对上机架进行拓扑优化-尺寸优化二级优化，拓扑优化并重新建模后，对其各个尺寸进行灵敏度分析，选择了5个对质量和安装裁刀部分z轴方向形变量影响较大的尺寸进行优化设计，将安装裁刀部分z轴方向最大形变量降低28.53%，所受最大等效应力减小59.81%，质量减轻167 kg，改善了帘布产生毛刺的情况。

The force situation of the upper frame during the cutting process of the steel wire cord cutting machine was analyzed, and the static simulation was conducted. Then, it was found that the main reason for the burrs on the cut cord was that the excessive deformation amount in the z-axis direction of the cutting blade installation increased the cutting gap too much, resulting in burrs in the middle part of the cut cord, and the allowable deformation amount in the z-axis direction of the upper frame was determined to be 0.020 mm. Furthermore, the modal analysis was conducted on the upper frame to verify its vibration reliability, and the two-level optimization of topology optimization and size optimization was carried out on the upper frame to solve the problem of burrs. After the topology optimization and remodeling, sensitivity analysis was conducted on its various dimensions, and five dimensions that had a significant impact on the quality and z-axis deformation amount of the cutting blade installation were selected for optimization design. The results show that the maximum deformation amount in the z-axis direction of the cutting blade installation is reduced by 28.53%, the maximum equivalent stress is reduced by 59.81%, and the weight is reduced by 167 kg, which improves the occurrence of burrs on the cord.
