Vibration Analysis of Four-bar Linkage with Elastic Links : 1st Report, Transverse Vibration of Overhanging Coupler

概要

論文の詳細を見る
The continuous mass distribution of an overhanging coupler in a four-bar linkage is replaced by a lumped mass model, and the ordinary differential equations of motion for transverse vibration of the coupler are derived employing finite difference approximations. Comparison shows very good agreement between the numerical solutions of the these equations and the experimental results for the coupler with an overhanging end at crank side in a crank-lever mechanism. According to the numerical and experimental examination, the overhanging coupler is greatly influenced by the mass of overhanging portion and there is a suitable range of the masses to decrease the bending deflection and strain due to transverse vibration of the coupler.
