基于Matlab的匀质摆杆所受转轴约束力分析

Analysis of the Constraint Force of the Spindle in Uniform Mass Distribution Rod of Fixed Axis Based on Matlab

分析重力场中匀质杆绕固定轴的摆动过程,给出轴对杆约束力的大小和方向随杆摆角和摆长变化的定量关系,利用Matlab分析了约束力的变化特点,更加直观形象地阐释了其变力属性。

The constraint force of the spindle in uniform mass distribution rod of fixed axis rotation is analysed in gravity field,and the quantified relationship between the magnitude and direction of constraint force and the oscillation angle and oscillation length is given.The relationship graph between them is given by Matlab.It is visual for the cognition of the variable force nature of the constraint.
