The design of the crankshaft and connecting rod mechanism based on P-V diagram

摘要

The design of good performance and long service life, crankshaft affects the engine performance and fuel economy. It can reduce the consumption of materials and manufacturing cost. Thermodynamic calculation of mixed gas cylinder is analysised based on P-V diagram drawing, It compared with theory and practice to optimize the design of the crankshaft and connecting rod mechanism of engine crank connecting rod mechanism. The paper comes up with the overall design of the crankshaft connecting rod mechanism through the analysis of force on the calculation and selection of the structure and size of the crankshaft.
