摘要
本文根据Eular-Bernolli梁理论及杆的纵向振动微分方程,提出了平面连杆机构计入分布质量的运动弹性动力学的数学模型。该模型是利用频率函数的展开式产生的多项式形函数的一种修正模型。
Based on the Euler-Bernoulli's Theory of the Beam and the differential equation for the longitudinal vibration of the bar, mathematic models in the motional elasticity dynamics of planar mechanical linkage that takes its mass distribution into account are established. The models are in a modified polynomial form function generated by means of the expansion of the frequency function.
