多电技术成为了飞机未来发展的一大趋势,是当下研究的热点,功率电传电静液作动系统是其核心技术之一。目前已有的或是正在研发的电静液作动器,主要采用旋转伺服电机驱动轴向柱塞泵的架构作为核心能源。轴向柱塞泵属于传统的液压部件,其最初设计的应用是为液压系统提供能源,并不是用作伺服系统的传动部件,因此虽结构成熟,但却相当复杂。如此复杂的结构作为伺服控制系统的传动环节,存在着摩擦磨损限制使用寿命、惯性较大限制响应速度,结构复杂难以余度配
Multi-electric technology has become a major trend in the future development of the aircraft. It is a hot spot in the present research. One of its core technologies is the hydrostatic transmission system of electric power transmission. Currently there are or are being developed electro-static liquid actuator, the main use of rotary servo-driven axial piston pump architecture as the core energy. Axial piston pump is a traditional hydraulic components, its initial design application is to provide energy for the hydraulic system is not used as a servo drive components, so although the structure is mature, but it is quite complicated. Such a complex structure as a servo control system, transmission links, there is friction and wear limit the service life, inertia larger limit the speed of response, the structure is complex and difficult to spend degrees
