描述了一种通过测量导弹在六个不同位置的转动惯量来计算导弹惯性积 ,进而计算导弹纵轴与主惯性轴夹角的方法。对长度较长、竖直放置在测试台上很困难的导弹 ,提出了将导弹纵轴倾斜一角度 ,间接计算纵向转动惯量的计算方法 ,使得在同一台设备上能测量导弹全部惯性张量。转动惯量通过扭摆法测量 ,在测量过程中 ,由于导弹转动速度很慢 ,可以忽略空气阻力的影响 ,有较高的测量精度。
A method of calculating the inertia product of a missile by measuring the moment of inertia of the missile at six different locations is described, and the method of calculating the angle between the longitudinal axis of the missile and the main inertial axis is also described. For long missiles that are difficult to place vertically on the test bench, a method of calculating the longitudinal moment of inertia indirectly by tilting the longitudinal axis of the missile is proposed, which makes it possible to measure the total inertial tensor of the missile on the same equipment. Moment of inertia measured by the twist method, the measurement process, the missile rotation speed is very slow, you can ignore the impact of air resistance, high measurement accuracy.
