Abstract:

According to the forming principle of hypocycloid , a prototype and a dynamical model of the intemal cycloid planetary gear mechanism for a single-cylinder engine are developed using Solidworks and ADAMS. The dynamical characteristics of the mechanism are then simulated to lay some foundations for the structuredesign and optimization design of the mechanism. Moreover, by the simulation and comparison between the cycloid single cylinder engine and the conventional 195 type engine , it is found that the cycloid engine surmounts the disadvantages of the conventional 195 type engine due to its simple sinusoidal piston motion , greatly reduces the piston sideforces , the piston friction and the cylinder wear, and can be used as a substitute for the conventional crank-connecting rod mechanism.

Key words: intemal cycloid diesel engine, planetary gear mechanism, dynamic characteristic
