摘要: 机械系统运转时,由于原动件上的力矩波动将引起机械速度的周期性波动,从而影响机械的工作精度,因此空间机构的速度波动分析是空间机构动力学中的一个重要的研究方向。以空间2自由度5杆RCCCR机构为例,建立运动微分方程,并求解其速度波动情况,进而为空间机构的速度波动调节提供了依据。

Abstract: The analysis of velocity fluctuation in spatial 5-link mechanism is presented. The Lagrangian differential equation of motion is adopted to analyze the velocity fluctuation. The angular velocity of the drive crank is calculated by programming on computer. The method and procedure can be extended to other spatial mechanisms.

Key words: Lagrange’s equation, Spatial 2-degree 5-link mechanism, Velocity fluctuation
