The Dynamic Synthesis of Spatial Mechanisms to Minimize the Kinetic Energy Fluctuation

摘要: 本文利用正定矩阵三角分解和本征参数坐标变换,首次推出两个公式,用于直接综合机构运动杆的连续分布质量参数。这些方法既保证了结果的合理,又消除了大多数约束不等式,从而大大提高了计算速度和精度。

Abstract: Using the triangular decomposition of a positive definite matrix and the coodinate transformation of characteristic parameters, this paper, for the first time, develops two equations, used for the direct synthesis of distribute-mass-parameters of motive links in spatial mechanisms. These techniques not only ensure reasdnable results but also eliminate the majority of constrained inequalities, thus enhancing computing speed and accuracy greatly.
