对于非对称结构,采用扭摆测量转动惯量的方法可以测量物体的惯性积。

◆测量方法:测量全部的六个惯性张量：Ix、Iy、Iz、Ixy、Ixz、Iyz。

◆对本转动惯量测量台,测量Iy,Iz,Iyz夹具水平安装,测Ixz，Ixy夹具倾斜45゜安装,测量Ix夹具竖直安装,有3种不同的空截情况,因此需要进行3种空载状态测量,6次加载状态测量,分别为:Iy空载、Ix空载、Ixy空载、ly加载、Iz加载、Iyz加载、Ixz加载、Iy加载、Ix加载。

主要技术指标:

转动惯量范围: 0.05kg.m2-0.5kg.m2；

转动惯量测量精度:±0.3%；

惯性积测量精度:±1%;

惯性主轴测量精度:±20；

输出参数:

六个中心惯性张量；

9个方向余弦,确定三条惯性主轴位置；

三个主转动惯量。

For asymmetric structures, the inertia product of an object can be measured by means of torsion pendulum measurement of moment of inertia.

◆ measurement method: measure all six inertial tensors: Ix、Iy、Iz、Ixy、Ixz、Iyz.

◆ this moment of inertia measuring table, Iy, of measurement Iz, Iyz fixture horizontal installation, ixz, survey ixy fixture tilt 45゜ install, Measuring ix fixture vertical mounting, There are three different types of interception, So three no-load measurements are needed, Six load state measurements, They are: iy no-load, ix no-load, ixy no-load, ly load, iz load, iyz load, ixz load, iy load, ix load.
