Abstract
Study of Effect of Friction on the Pin of Pantograph Mechanism
Highlights
Pantograph is a four bar mechanical linkage used to trace a motion and can scale it up or down
We have analyzed the effect of friction in terms of equivalent stress and shear stress
Engineers Handbook [3] is a website that provides value of coefficient of friction for different materials like aluminum, steel, copper, etc. This data is used throughout the simulation of the pin and links
Summary
Pantograph is a four bar mechanical linkage used to trace a motion and can scale it up or down. Problem generally faced in applying this mechanism into practical application includes reduced accuracy in tracing the figures. Reason for this is the enlarged values of stresses due to friction, inertia and gravity effects for bigger mechanism. Engineers Handbook [3] is a website that provides value of coefficient of friction for different materials like aluminum, steel, copper, etc. This data is used throughout the simulation of the pin and links. Design of mechanism For the better understanding of the working of pantograph mechanism, a wooden model was constructed.
