The invention relates to the technical field of aircraft landing gear tests, and particularly discloses a large-torque high-speed blade swing motor servo system for aircraft landing gear tests, which is characterized in that an oil source conveys hydraulic oil in a recovery oil tank into an energy accumulator group, and the energy accumulator group is communicated with a first port of a servo valve; a second port of the servo valve is communicated with an oil liquid input port of the recovery oil tank, a third port of the servo valve is communicated with a first oil liquid conveying port of the blade motor assembly, and a fourth port of the servo valve is communicated with a second oil liquid conveying port of the blade motor assembly. High-pressure hydraulic oil in the energy accumulator set is input into the blade motor assembly and then output, precise control over the swing start, the swing angle and the rotating speed of the blade motor assembly is achieved, a large amount of high-pressure hydraulic oil is rapidly released through the energy accumulator set, and the instantaneous flow of the system is sharply increased; and the rotating speed and the torque value of the blade motor assembly can be greatly increased in a short time, so that the power of the motor reaches extremely high peak power.
本发明涉及飞机起落架测试技术领域,具体公开了一种用于飞机起落架试验的大扭矩高速叶片摆动马达伺服系统,油源将回收油箱中的液压油输送至蓄能器组中,蓄能器组与伺服阀的第一端口连通,伺服阀的第二端口与回收油箱的油液输入口连通,第三端口与叶片马达组件的第一油液输送口连通,第四端口与叶片马达组件的第二油液输送口连通,在阀门控制器对伺服阀的控制下,使得蓄能器组中的高压液压油输入叶片马达组件后再输出,实现了对叶片马达组件摆动的起始、摆动角度、转动速度的精准控制,且通过蓄能器组快速大量释放高压液压油,系统瞬间流量急剧增高,短时间内能够让叶片马达组件转速和扭矩的值大大增加,使马达的功率达到极高的峰值功率。
