刚体平面运动的数值计算

Numerical computation of rigid body planar motion

在理论力学刚体平面运动的教学中,为了分析刚体平面运动每一瞬时的运动参数,采用复数法进行运动分析的理论公式推导,并用VB语言编程进行数值计算,得出刚体的角速度和角加速度,进而得出刚体上每一点的运动参数,与采用基点法和瞬心法得出的结果相比较,加深学生对刚体平面运动概念的理解,有助于提高教学效果和培养学生的综合素质。

In theoretical mechanics teaching, a complex number method is proposed to analyses transient motion of the rigid body planar motion, and making computer program by VB, by which to get instantaneous angular velocity and instantaneous angular acceleration of rigid body, compare to the result by basing-point method. Introducing numerical computation to rigid body planar motion will greatly help to improve the teaching results and the students＇ comprehension quality in a all-round way,
