摘　　要：根据某无人直升机的飞行测量,获得其陀螺安装板的振动水平,对该陀螺减振器的频率和阻尼参数提出要求,设计了两种减振器,通过地面加速试验和试飞,优选设计方案。这种参数测定和试验选型的方法可为其他减振器设计提供借鉴。The vibration magnitude of the fixing board to gyro was measured based on the flight test of unmanned helicopter.With the measurement result,the design parameters of the gyro,such as frequency and damp,were determined.And two types of vibration absorber were designed and manufactured by use of those parameters.Further,the good design was selected through flight test and accelerated life test.The method may provide reference for other vibration absorber design.
