摘 要: 分析了刚体转动惯量实验仪实验中的误差来源,指出时间测量不准确与阻力矩是产生误差的主要因素,测量了阻力矩的大小,定量分析了阻力矩的影响,当砝码质量为20g时,阻力矩与砝码的拉力矩之比可达19%。 This paper analysised the source of error of the experiment of experimental instrument of the rigid body moment of inertia and pointed out the main factors causing errors is disaccurate time measurement and moment of resistance.We measured moment of resistance and quantitative analysised of the influence of the moment of resistance.When the mass is 20g,the ratio of moment of resistance and tension moment of weight is up to 19%.
