技术介绍
气压传动与控制系统具有高能量密度、低噪音、无冲击等优势,在国民经济和国防工业的各个行业已成功应用多年。传统的气压动力系统通常都是由尺寸较大的电动机和机械式气泵进行驱动的,并通过换向阀、减压阀及调速阀等多类型阀的联合作业实现输出力、速度及位置等的有效控制,故体积庞大、结构连接及控制比较复杂,应用上具有很大的局限性:无法用于航空航天、行走机器人等微小系统及远程控制系统;同时,由于现有气压动力系统采用种类繁多的气阀进行联合控制,难以实现驱动力、速度及位置的精确控制与调节,无法用于精密机械加工与装配、精密测量、精密光学驱动等要求驱动、定位及控制精度高的领域。因此人们相继提出了多种类型的微小型气缸及气动系统,如中国专利201510843026.7、201310132556.1、201410611173.7等,因现有气缸或气动系统均由固定频率驱动的,实际工作中其驱动力及速度受工作负载影响较大,当具体工况下的驱动元件谐振频率与所设定的激励频率偏差较大时,气体输出量和压力都将大幅度下降,且根据设定驱动电压及频率计算所得的驱动力及速度精确度也较低。
