曲柄滑块机构是指用曲柄和滑块来实现转动和移动相互转换的平面连杆机构，也称曲柄连杆机构。曲柄滑块机构广泛应用于往复活塞式发动机、压缩机、冲床等的主机构中，把往复移动转换为不整周或整，周的回转运动；压缩机、冲床以曲柄为主动件，把整周转动转换为往复移动。这里使用运动学知识，对其运动进行解析，并用MATLAB为其设计仿真模块。、运动学分析实例题目对图示单缸四冲程发动机中常见的曲柄滑块机构进行运动学仿真。已知连杆长度：0：0，：04m，连杆的转速：：@：@设曲柄以匀速旋转，：500“初始条件：一一0。仿真以为输入，计算叫和0仿真时间5s。曲曲柄滑块机示首图运动分析建立封闭矢量方程． r2+r3:r1 (9)r2cos62+r3cos63:r1r2sin92+r3sin83:O (10) rizr2cos82+r3cos83 (11)rizr2cos82+r3cos83-r2w2sin62+r2w2cose2+r3u3cos83zo (12) r3sin63 -r3cos93 0]03VI]r2w2cos82] AX:Bö (13)MATLABfunctionvarargout=zl(varargin)%ZlMATLABcodeforzl.fig11,byitself.createsanewZIorraisestheexistingsingleton*H=ZlreturnsthehandletoanewZlorthehandletotheexistingsingleton*callsthelocalfunctionnamedCALLBACKinZI.Mwiththegiveninputarguments.createsanewZlorraisestheexistingsingleton*.Startingfromtheleft,propertyvaluepairsareappliedtotheGUIbeforezlOpeningFcngetscalled.Anunrecognizedpropertynameorinvalidvaluemakespropertyapplicationstop.AllinputsarepassedtozlOpeningFcnviavarargin.*SeeGUIOptionsonGUIDE'sToolsmenu.Choose"GUIallowsonlyoneinstancetorun(singleton)"%Seealso:GUIDE,GUIDATA,GUIHANDLES%Edittheabovetexttomodifytheresponsetohelpzl%LastModifiedbyGUIDEv2.529-Dec-2016%Begininitializationcode-DONOTEDITgui_Singleton=1;guiState=struct('guiName',mfilename,'guiSingleton',guiSingleton,'gui_OpeningFcn',zl_OpeningFcn,.'guiOutputFcn'JzlOutputFcn,'gui_LayoutFcn','guiCallback',ifnargin ischar(varargin{l))gui_State.gui_Callback=str2func(varargin{1});endifnargoutvarar€in{:});guimainfcn(guiState,varargin{:));end%Endinitializationcode-DONOTEDIT%Executesjustbeforezlismadevisible.functioneventdata,handles,varargin)%Thisfunctionhasnooutputargs,seeOutputFcn.%hObject handletofigure%eventdatareserved-tobedefinedinafutureversionofMATLAB%handles structurewithhandlesanduserdata(seeGUIDATA)%varargin commandlineargumentstozl(seeVARARGIN)%Choosedefaultcommandlineoutputforzlhandles.output=hObject;%Updatehandlesstructureguidata(hObject,handles);axes(handles.axes3)mapl=imread('l.bmp');imshow(mapl)%UIWAITmakeszlwaitforuserresponse(seeUIRESUME)%uiwait(handles.figurel);%Outputsfromthisfunctionarereturnedtothecommandline.functionvarargout=zl_OutputFcn(hObject,eventdata,handles)%varargoutcellarrayforreturningoutputargs(seeVARARGOUT);%hObjecthandletofigure%eventdatareserved-tobedefinedinafutureversionofMATLAB%handles structurewithhandlesanduserdata(seeGUIDATA)%Getdefaultcommandlineoutputfromhandlesstructurevarargout{l}=handles.output;%ExecutesonbuttonpressinpushbuttonRun.functionpushbuttonRun_Callback(hObject,eventdata,handles) rad'stheta3(i)=asin(-r2tr3*sin(theta2(i)));endaxes(handles.axesl)96ib[JÆe1plot(x11/1000romiga3);xlabel(VlFftljJ(t/s)v)(rad/s)axes(handles.axes2)%Till*2xlabel(VIFjtljJ(t/s)v)VI(m/s)%hObject handletopushbuttonRun(seeGCBO)%eventdatareserved-tobedefinedinafutureversionofMATLAB%handles structurewithhandlesanduserdata(seeGUIDATA)functioneditlCallback(hObject,eventdata,handles)%hObjecthandletoeditl(seeGC80)%eventdatareserved-tobedefinedinafutureversionofMATLA3%handles structurewithhandlesanduserdata(seeGUIDATA)%Hints:get(hObject,'String')returnscontentsofeditlastextstr2double(get(hObject,'String'))returnscontentsofeditlasadouble%-Executesduringobjectcreation,aftersettingallproperties.functioneditlCreateFcn(hObject,eventdata,handles)%hObjecthandletoeditl(seeGC80)%eventdatareserved-tobedefinedinafutureversionofMATLAB%handles empty-handlesnotcreateduntilafterallCreateFcnscalled%Hint:editcontrolsusuallyhaveawhitebackgroundonWindows.See'SPCandCOMPUTER,ifispc&&isequal(get(hObject,'BackgroundColor'),get(OJ'defaultIJicontrolBackgroundColor'))set(hObject,'BackgroundColor','white');end%-ExecutesonbuttonpressinpushbuttonExit.functionpushbuttonExitCallback(hObject,eventdata,handles)switchssdelete(handles.figurel);end%hObject handletopushbuttonExit(seeGCBO)%eventdatareserved-tobedefinedinafuturev
