摘要：

为了改善传统液压驱动的金属屑压块机传动效率低下、结构复杂等缺陷，设计了一种新型直驱式液压系统应用于金属屑压块机中，通过采用A4V闭式变量泵和交流伺服电机组合，构建了全新的直驱液压单元。在AMESim软件平台中，设计排量调节规则并验证规则的可行性，实现了对液压缸的闭环位置控制。通过仿真研究表明，改进后的系统降低了装机功率，有利于延长伺服电机寿命，同时提升金属屑压块机的工作能力。

For the defects of the metal shaving press directed by traditional hydraulic system, such as the inferior transmission efficiency and the complex structure, a new direct-drive variable displacement hydraulic system was designed for the metal shaving press. Through the combination of the Rexroth A4V close circuit variable pump and AC servo motor, a new direct-drive hydraulic unit was built. In the platform of AMESim software, the strategy of displacement adjustment was designed and the feasibility was verified, and the close loop control of position for hydraulic cylinder was realized. The simulation research shows that the new system saves the installed power, and is beneficial for the longevity of the servo motor. At the same time, the working capacity of the metal shavings press is improved.
