摘　　要：伸杆是一种可从其初始状态展开后把卫星上的勘测仪器送至指定位置的重要设备。在研制过程中,伸杆的零重力展开测试是一项必不可少的测试内容,因此需要一套重力补偿装置,来模拟零重力环境。从支撑补偿重力的角度,研制了一种"杠杆+配重"结构形式的新型重力补偿装置,利用静力平衡原理消除重力影响。通过调节配重的位置,可根据工况调节补偿力的大小,更好满足重力补偿的要求。试验验证了该补偿装置的有效性。The telescopic rod is a type of important device which can be used to send the some surveying instruments on the satellite form the initial state position to the desired position.In the process of development,the test for the zero gravity of the telescopic rod is essential in its extendibility experiments.For this,a gravity compensation device is needed,which can be used to simulate a zero gravity environment.In this paper,form an angle of support compensating gravity,a new gravity compensation device with“levers add counter weights”structure form is developed,which is used to balance the gravity according to the principle of static equilibrium.The compensation force can be adjusted according to the working conditions by adjusting the position of the counter weights,thus better meeting the requirements of the gravity compensation.The experiment results demonstrate the effectiveness of the compensation device.
