摘要
介绍了存在阻尼条件下物体转动惯量测量的数学模型——线性微分方程模型;利用气浮转动惯量测量系统对线性模型进行了实验验证。结果表明空气阻尼对大尺寸复杂形状物体的转动惯量测量影响较大;线性模型的补偿效果有限,对于阻尼条件下的高精度的转动惯量测量,有必要进行新的补偿算法的研究。
A mathematical model,linear differential equation model,for measuring the moment of inertia of objects under damp conditions is introduced.By utilizing the air-floatation inertia measurement system,experimental validation of the linear model is carried out.The results show that air damping has a significant impact on measuring the moment of inertia of objects with large scale and complex shape.For the high-precision inertia measurement under damp conditions,the compensation affects of the previous linear model are limited and research on the new compensation method is needed.
