RRP平面連桿機(jī)構(gòu)的動(dòng)態(tài)仿真
 
 摘要：機(jī)構(gòu)的運(yùn)動(dòng)分析，主要獲得機(jī)構(gòu)中某些構(gòu)件的位移，角速度和角加速度，以及某些點(diǎn)的軌跡，速度和加速度。機(jī)構(gòu)的動(dòng)力分析，主要是在運(yùn)動(dòng)學(xué)的基礎(chǔ)上，由已知工作阻力，求出運(yùn)動(dòng)副的約束反力和驅(qū)動(dòng)力，為選擇和設(shè)計(jì)軸承，零件強(qiáng)度的計(jì)算及選擇原動(dòng)機(jī)提供原理。
 本文以機(jī)構(gòu)的組成原理為出發(fā)點(diǎn)，主要以RRPⅡ組連桿機(jī)構(gòu)為分析對(duì)象，用復(fù)數(shù)向量推導(dǎo)出曲柄，RRPⅡ級(jí)桿組的矩陣數(shù)學(xué)模型，并編制了用于MATLAB/Simulink仿真的函數(shù)，這樣以MATLAB/Simulink為平面連桿機(jī)構(gòu)運(yùn)動(dòng)分析和動(dòng)力分析的平臺(tái)，可以搭建RRPⅡ級(jí)桿組組成的平面連桿機(jī)構(gòu)的運(yùn)動(dòng)學(xué)和動(dòng)力學(xué)的仿真模型并進(jìn)行仿真，并觀察參數(shù)是如何變化的。

Dynamic Simulation of RRP Planar Linkage

Abstract:Analyzing the movement of institutions, mainly obtain displacement, velocity and Angle acceleration, and some points trajectory, speed and acceleration in some institutions of displacement。Organization of the dynamic analysis of kinematics, mainly in, on the basis of the known by the work resistance, the motion pair constraint force and driving force for the selection and design of bearings, strength calculation, and select engine provide principle.
This is Based on the principles of the institution as a starting point,with RRP Ⅱ group of linkage mechanism mainly,use the plural vector derivation the Matrix mathematic model of Ⅱ level. RRP pole ,crank.And prepare the Simulation of function of MATLAB/Simulink .So ,MATLAB/Simulink is used for platform of planar linkage mechanism.This can build RRP Ⅱ level rod group composed of planar linkage mechanism of the kinematics and dynamics simulation model and simulation.And observed how is the change of parameters.
