新型曲柄连杆机构运动学模型的研究

Kinematics Model of A New ICE Mechanism

提出一种用于内燃机的新型曲柄连杆机构,建立了该机构的运动学数学模型,并编制了计算机程序。根据程序输出结果对新型曲柄连杆机构的活塞运动规律进行了重点分析。结果发现,经过改进的新型曲柄连杆机构具有明显的活塞运动的非对称性,并简析了这种新特性有可能对内燃机工作过程产生的影响。

A new kind of mechanism for internal combustion engines is put forward with the kinematics model and its computer program.Based upon the output results of the program,the emphases of the analysis are put to the kinematics of the new engine.The results show that the engine with new mechanism performs evident unsymmetrical characteristics on the piston movement.Finally,the possible affection of such new characteristic on the working process of ICE is discussed simply.
