800MN巨型模锻液压机是关系国家安全、经济发展的战略性设备,也是航空制造业的基础性设备。同步控制系统是巨型模锻液压机上必备的关键装置,其同步控制性能的好坏将直接决定产品的质量,而同步平衡缸则是同步控制系统中的关键部件。通过建立力学模型,设计了同步平衡缸。并借助MARC软件对其进行有限元分析,对结构薄弱之处进行了优化,有效的减小了活塞的挠曲程度,降低了活塞承受的弯曲应力,同时连接轴与活塞等效应力大幅下降。为同类产品的设计提供了参考。
800MN Jumbo forging hydraulic press is a strategic equipment that is related to national security and economic development as well as the basic equipment of the aviation manufacturing industry. Synchronous control system is a giant forging hydraulic press essential essential device, the synchronous control performance will determine the quality of the product directly, and synchronous balancing cylinder is a key component of synchronous control system. By establishing a mechanical model, a synchronous balancing cylinder is designed. The finite element analysis was carried out with MARC software to optimize the structural weakness, effectively reducing the deflection of the piston, reducing the bending stress to the piston, and reducing the equivalent stress of the connecting shaft and the piston. For the design of similar products provide a reference.
