论文摘要RRR平面连杆机构的动态仿真学生姓名：黎宝龙 班级：0781051 指导老师：朱保利摘要：平面连杆机构的动态仿真分为机构的运动分析和动力分析两种。机构的运动分析，主要获得机构中某些构件的位移、角速度和角加速度，以及某些点的轨迹、速度和加速度，它是机械设计及评价机械运动和动力性能的基础，也是分析现有机械优化综合新机械的基本手段；机构的动力分析，主要是在运动学分析的基础上，由已知工作阻力，求出运动副的约束反力和驱动力（或力矩），为选择和设计轴承、零部件强度的计算及选择原动机提供理论依据。本文用矢量和矩阵理论建立了适用于MATLABSIMULINK仿真的曲柄、RRR级杆组运动学和动力学数学模型，以该数学模型编制了M函数仿真模块，对给定的RRR四杆机构和RRR-RRR六杆机构进行了建模和仿真，通过仿真得到各转动副的反力及驱动力矩其主要目的是以构成机构的基本杆组为仿真模块，搭建杆组MATLABSIMULINK仿真模型，可以对不同类型平面连杆机构进行运动学和动力学仿真和分析。关键词：连杆机构 运动学 动力学 MATLAB/SIMULINK 仿真 指导老师签名：Dynamic Simulation of RRR Planar LinkageStudent name: Li Bao Long class: 0781051 Supervisor: Zhu Bao LiAbstract: Dynamic simulation of planar linkage is divided into two types of kinematic analysis and dynamic analysis. The Kinematic analysis, which is the basis of the mechanical design, evaluation of mechanical motion and the dynamic performance, and it is the basic of Analyze Optimal Synthesis of new machinery of existing machinery. the main access to institutions of certain components of the displacement, angular velocity and angular acceleration, and some points of track, speed and acceleration. The Dynamic Analysis, which provides a theoretical basis for Selecting and designing of bearings, parts strength calculation and selection of the original motivation, Constraints derived anti-vice campaign and the drive force (or torque) based on the analysis of kinematics and the Working resistance.In this paper, using vector and matrix theory applicable to the MATLAB / SIMULINK simulation of the crank, RRR class bar group mathematical model of kinematics and dynamics, and using this mathematical model draw up M Function Simulation Module, a RRR four -bar linkage and a RRR-RRR six institutions were taken as example ,the procedures of modeling and simulating. Obtain the deputy of the anti-rotation force and driving torque through the simulation. Its main purpose is to constitute the body of the bar group Simulation Module, building the MATLAB / SIMULINK simulation model for the bar group, to do the kinematic and dynamic simulation and analysis for different type
