摘　　要：本文根据某汽车零部件厂汽车后桥壳胀形工艺,充液加载路径过程中两侧水平缸保持位置同步控制。电控系统采用SIMATIC S7-1500系列PLC控制器进行设计,水平缸同步控制策略采用优化主从同步控制方式,有效地将响应过渡过程中的动态同步误差控制在允许范围内,提高了同步控制精度,满足内高压成形机位置同步系统控制要求。This paper focuses on the position synchronous control of the two horizontal cylinders during the fluid-filling and loading process of an automotive rear axle housing hydroforming system,based on the manufacturing process from a specific automotive component factory.The electronic control system is designed using the SIMATIC S7-1500 series PLC controller,while the synchronous control strategy for the horizontal cylinders adopts an optimized master-slave synchronization method.This approach effectively limits dynamic synchronization errors during the response transition process to within acceptable ranges,enhancing the precision of synchronous control and meeting the position synchronization requirements of the hydroforming system.
