V带电算程序设计简介

一、程序设计简介本程序采用Matlab语言编程，用Matlab中的GUI图形界面来实现程序的界面显示输入输出结果一目了然，简单实用。本程序实现的是V带传动中的小带轮设计，能满足正常情况下所有种类的V带的自动计算。本程序集成了V带设计过程中所有需要的用到的图表，既不用查取任何书籍即可完成计算，并且可同时显示九种输出结果，便于比较各种不同选择之间的差别，从中选择最好的结果。程序界面如下：图1二、V带程序框图下图为V带程序的框图，它按照普通V带的程序设计计算过程以及程序语言的特点编写而成，通过框图能直观的了解到程序的工作过程，同时也为程序的编制带来很大方便。程序框图如下：开始输入P，n1，i的值选择工作载荷情况，原动机类型，及一天工作的时间得到KA的值计算Pd，并根据型图选型根据带型，输入最小带轮直径dd1dd2=i*dd1选取标准直径确定dd2V=10006011nddvvmax？)(2)(7.021021ddadddddd输入初估中心距a0计算基本带长Ld1，查取基准长度Ld，计算实际中心距a，小轮包角1查取k1,k2,k3,ki,kb,ka,kl,计算的P0，P0Z=kklPPPd)00(Z10计算F0，FQ，输出Ld，Z，a,dd1,dd2,F0,FQ计算下一种直径？结束AAB减小直径NYBYNYN三．程序的运行过程首先要运行本程序，需要Matlab的运行环境，而且由于版本的更新与Matlab语言的不断完善，本程序需要Matlab2009a以上的版本才能够正确运行，版本过低导致有的函数软件不能识别，会报告错误。有了Matlab的运行环境之后，双击“.m”的程序源文件进入文件编辑器中，单击菜单栏中的绿色三角形既运行按钮，或者在当前界面下直接按“F5”即可运行本程序，成功后将会弹出如图1的界面。1.输入原始数据包括，功率P，转速n1，传动比i，输入完成后点击确定，则提示框显示下一步应该进行的操作，如下图所示：图22.按照提示的信息，进行接来下的操作，选择带轮的工作情况条件，如下图：图33.选择完工作条件之后，程序会显示选择V带型号的图表如图3，根据提示栏提示的信息选择V带型号，本图所示数据选择A型带，如下图：图44．根据提示信息，选择小带轮直径，并单击确定，如下图：图55．点击确定后，程序自动算出中心距范围。并显示在提示栏中，从中初选中心距，输入完成后点击“计算”，如下图：图66.点击“计算”后，输出数据就显示在界面上，包括带型，基准长度，V带根数，中心距，大小带轮直径，初压力，压轴力。如果要进行下一组数据的计算，点击“计算下一组数据”，程序自动将输入数据清空，进行下一轮计算，如下图：图77.从新按照上述步骤从新输入数据，输入完成后，点击“计算”，输出数据将显示在计算结果的第2行里。计算超过九组数据时，计算结果列表将自动增加行来满足显示输入，如下图：图88．本程序还能提示数据选择不当而产生的错误，如下图，提示V带根数大于10时，需要从新选择数据。图9四、程序原代码、%本程序运行需要在matlab2008b及以上版本中才能正确运行，如果运行出错，请老师升级matlab版本即可%H=figure('position',[100,50,1100,700],'name','V带设计','menubar','none');b=1axes('position',[0.28,0.48,0.45,0.55])xy=imread('jin.jpg')imshow(xy)a1=[0,0,0,0;0,1.0,1.1,1.2;0,1.1,1.2,1.3;0,1.2,1.3,1.4;0,1.3,1.4,1.5];a2=[0,0,0,0;0,1.1,1.2,1.3;0,1.2,1.3,1.4;0,1.4,1.5,1.6;0,1.5,1.6,1.8];dd=[0,20,50,75,125,200,355,500];v=[0,25,25,25,25,25,30,30];ld=[200,224,250,280,315,355,400,450,500,560,630,710,800,900,1000,1120,1250,1400,1600,1800,2000,2240,2500,2800,...3150,3550,4000,4500,5000];DD=[0,0,0,0;20,28,35.5,40;50,63,71,80;75,90,100,125;125,140,160,180;200,250,315,400;355,400,450,500;500,560,630,710]DD2=[20,28,35.5,40,50,63,71,75,80,90,100,125,140,160,180,200,250,315,355,400,450,500,560,630,710]k=[0,0,0.264,0.449,0.794,1.48,3.15,4.57;0,0,7.44,19.02,50.6,143.2,507.3,951.5;0,0,0.441,0.765,1.31,2.34,4.77,7.06];kb=[0,0,0.2925,0.7725,1.9875,5.625,19.95,37.35];ki=[1,1.0136,1.0276,1.0419,1.0567,1.0719,1.0875,1.1036,1.1202,1.1373];alf=[90,100,110,120,130,140,150,160,170,180,190,200,210,220];ka=[0.68,0.73,0.78,0.82,0.86,0.89,0.92,0.95,0.98,1.00,1.05,1.10,1.15,1.20];m1=[0,0.02,0.06,0.1,0.17,0.3,0.6,0.9]kl=[0,0.81,0,0,0,0,0,0;0,0.82,0,0,0,0,0,0;...0,0.84,0,0,0,0,0,0;0,0.870,0,0,0,0,0,0;...0,0.9,0,0,0,0,0,0;0,0.92,0,0,0,0,0,0;...0,0.96,0.87,0,0,0,0,0;0,1,0.89000,0,0,0,0,0;...0,1.0200,0.9100,0,0,0,0,0;0,0,0.940000000000000,0,0,0,0,0;...0,0,0.96000,0.81000,0,0,0,0;0,0,0.990000000000000,0.830000000000000,0,0,0,0;...0,0,1,0.8500,0.820000,0,0,0;0,0,1.03000000000000,0.870000000000000,0.840000000000000,0.830000000000000,0,0;...0,0,1.06000,0.89000,0.860000000000000,0.860000000000000,0.830000000000000,0;...0,0,1.08000,0.910000,0.880000000000000,0.880000000000000,0.860000000000000,0;...0,0,1.10,0.930000,0.900000000000000,0.910000000000000,0.890000000000000,0;...0,0,1.14000,0.96000,0.920000000000000,0.930000000000000,0.910000000000000,0;...0,0,1.160000,0.99000,0.950000000000000,0.950000000000000,0.930000000000000,0;...0,0,1.18000,1.010,0.980000000000000,0.970000000000000,0.960000000000000,0;...0,0,0,1.0300,1,0.9000,0.980000000000000,0;0,0,0,1.06000000000000,1.03000000000000,1.02000000000000,1,0;...0,0,0,1.0900000,1.050000,1.04000000000000,1.03000000000000,0;...0,0,0,1.11000,1.07000,1.07000000000000,1.06000000000000,0;...0,0,0,1.1300,1.090000,1.09000000000000,1.08000000000000,0;...0,0,0,1.17000,1.130,1.12000000000000,1.11000000000000,0;...0,0,0,1.1900,1.1500,1.15000000000000,1.14000000000000,0;...0,0,0,0,1.180,1.1800,1.17000000000000,0;0,0,0,0,0,1.21000000000000,1.20000000000000,0;0,0,0,0,0,1.23000000000000,1.22000000000000,0;]xing={0,'Y型','Z型','A型','B型','C型','D型','E型'}edit1=uicontrol(H,'style','edit','position',[150,580,100,50],'fontname','楷体','fontsize',12,'backgroundcolor','w','callback',...'P=str2num(get(edit1,''string''))');edit2=uicontrol(H,'style','edit','position',[150,510,100,50],'fontname','楷体','fontsize',12,'backgroundcolor','w','callback',...'n1=str2num(get(edit2,''string''))');edit3=uicontrol(H,'style','edit','position',[150,440,100,50],'fontname','楷体','fontsize',12,'backgroundcolor','w','callback',...'i=str2num(get(edit3,''string''));');edit4=uicontrol(H,'style','edit','position',[950,530,100,50],'fontname','楷体','fontsize',12,'backgroundcolor','w','callback',...['dd1=str2num(get(edit4,''string''));','dd2=dd1*i;','V=(pi*dd1*n1)/60000;',...'fornn=1:25;',...'xx=dd2-DD2(nn);',...'ifxx0;',...'break;',...'end;',...'end;',...'ifdd2-DD2(nn-1)DD2(nn)-dd2;',...'dd2=DD2(nn);',...'else;',...'dd2=DD2(nn-1);',...'end;']);edit5=uicontrol(H,'style','edit','position',[950,390,100,50],'backgroundcolor','w','fontname','楷体','fontsize',12,'callback',...'a0=str2num(get(edit5,''string''))')text1=uicontrol(H,'style','text','position',[50,580,100,50],'back
