Research of Connecting Rod's Envelope Track Equation with GeoGebra
Connecting rod is one of the important parts of crank-connecting rod mechanism of internal combustion engine,the kine-matic characteristics of the connecting rod are emphatically analyzed.With the help of the software GeoGebra,the model of the crank-connecting rod mechanism and the motion track of the connecting rod are established.This paper analyzes the envelopment of the edge line of the connecting rod motion track from the angle of mathematical analysis,and deduces its envelopment equation,which only needs to determine the connecting rod length and the crank radius to obtain the connecting rod envelopment line,thus,the envelope e-quation can be transformed into the drawing of the connecting rod envelope curve in the 3D software,and the design efficiency can be improved.
