摘　　要：以双连杆内燃机为背景,采用基于底层语言(VC++6.0)与大型软件包(Pro/Engineer)二次开发相结合的开发模式,研究了内燃机装配仿真系统的总体结构,并建立了1126内燃机参数化模型。在此基础上,运用多体动力学的方法对内燃机曲柄连杆机构进行了动态仿真分析,得到了活塞的升程、速度、加速度变化规律,为内燃机的设计改进提供了重要依据。Based on dual connecting rod I.C. engine, and a combination of Visual C++6.0 with integrated software package Pro/Engineer, an assembly simulation system is presented in this paper. A set of CAD software system is studied through mechanics analysis and 1126 I.C. engine parameter model is constructed. On the basis of above study, dual connecting rod linkage has been dynamically simulated by multi-body method and the variation laws as to lift height, speed and acceleration have been concluded, laying a vital foundation for the design and improvement for I.C. engine.
