In this paper descibes the friction losses of double crank and connecting rod mechanism high speed diesel engine are calculated by computer The computed results show that the friction losses of double crank the connecting rod mechnism SLG195 diesel enfine are about 0.72kW,less than that of single crank and connecting rod mechanism S195diesel engine.
Taking the crank and connecting rod mechanism as an example,based on finite element method and multi-body dynamics simulation,the calculation approach of shock response of components of the diesel engine under operation was put forward.
the text studied dynamics computersimulation of single-cylinder ICE? crank-connecting rod mechanism0Using Pro/Engineer, the CAD software, 3D solid model of the mechanism wasbuilt and parts of the mechanism was assembled to piston components connectingrod component and crank component.
应用三维CAD软件Pro/Engineer建立曲柄连杆机构各组成零件的几何模型，并利用该软件的装配功能将零件装配成活塞组件、连杆组件和曲轴组件，然后与多刚体动力学分析软件（Working model 3D）接口，建立曲柄连杆机构的多刚体动力学模型，进行动力学分析模拟。
The bearing pairs wear and tears of crank-connecting rod mechanism are the main wear and tears in an internalcombustion engine,which reduce its average indicated pressure and indicated thermal efficiency.
Based on initial force model for single cylinder engine, the relationships between the angle of rotating mass of the crankshaft-connecting rod, the ratio of rotating mass to reciprocating mass and the maximal inertial force, the unbalance ratio were investigated.
The disadvantage that non-geometry engineering information can not be expressed by geometry model is solved by definition,classification of feature and foundation of feature lib. And this is the base to generate various similar complex component of the crank gear and the base to information reapplication.
