Mechanical system dynamics is the branch of dynamics which is oriented to mechanical mechanism and mechanical system. The research methods mainly is establishing equivalent dynamic model according to the mechanical system, then use dynamics basic principles and methods(Newtons second law,dalemberts principle,Lagrangian equations of motion,Kane equation,influence coefficient method,transfer matrix method etc) to solve the model. It is usually that these several aspects are researched. Mechanical system dynamics according to systemic characteristics of mechanical system generally divides mechanical system into rigid mechanical system,Rigid planar mechanism of inertial force balance,Mechanical systems with elastic components,Flexible rotor systems vibration and balance,Clearance joint mechanical systems,mechanical system with variable mass component etc. The solution of dynamic equation can be Euler method,runge kutta method,Solution of differential equations with higher order differential equations,kinetic equation in the form of Matrix etc. The design mainly researches single-degree of freedom mechanical system dynamics. It is taking crank as the research object and establishing the dynamic model for calculating and also using Microsoft Visual C 6.0 as a tool to analysis and making the model modular. Key words：dynamics；emulation；VC++；Crank Mechanism；Drawing 。 本设计在学习有关机械系统动力学和Microsoft Visual C++ 6.0知识的前提下，实现曲柄机构运行状态参数分析计算，并且根据参数绘制状态图示。机械系统动力学是本设计的理论基础，在此对机械系统动力学和Microsoft Visual C++ 6.0的有关知识进行简要介绍。 1.1 机械系统动力学 1.1.1 机械系统动力学学科简介 机械动力学是应用理论力学基本理论解决机械系统中的动力学问题的一门学科，其核心问题是建立机械系统的运行状态与其内部参数、外界条件之间的关系，建立机械系统等效模型，从而找到解决问题的
