Abstract
First, this paper analysis the working conditions and design requirement of crankshaft, piston, and connecting rod mechanism by using the related parameters of Audi l-V6-FSI- engine as reference. Select the material and version of different parts, determine the main structure size and check them in accord with the requirement. Then, set up three-dimensional entity models of crankshaft, piston, and connecting rod mechanism parts with the three-dimensional modeling software UG. By defining the corresponding connection relationship to assemble the piston component and connecting rod component respectively. After assembly, motion simulation and detecting the movement interference are necessary. Finally, analysis the motion and force in motion of crankshaft, piston and connecting rod mechanism based on kinematics and dynamics of theoretical knowledge. And the related analysis and results can lay a foundation for the future design of engine work.
Key words: engine; Connecting rod mechanism; UG; three-dimensional design; piston
