一、设计题目
题目4 绘制梁的剪力弯矩图 输入:
1.梁的总长度l
2.支撑条件及量的各区段长度输入(左、右固定端悬臂梁;简支梁;左、右、双外伸梁)
3.各载荷大小、作用位置及方向(qi、ai、bi;pj、cj、mk、dk) 输出:

二、程序介绍 1、简介
本程序编译平台为MATLAB,能够对六种梁(左固定端悬臂梁、右固定端悬臂梁、简支梁、左外伸梁、右外伸梁、双外伸梁)在集中载荷、均布载荷及弯矩作用下的剪力、弯矩进行求解并绘制剪力、弯矩图。本程序基于MATLAB的图形用户界面(GUI)功能,操作简单、运算稳定、界面简约美观,有良好的交互性。 2、程序使用方法
此程序运行环境为安装有MATLAB R2011a或以上版本的计算机。要运行此程序,首先打开MATLAB,在其中打开“KaiShiJieMian.m”文件,在函数编辑窗口里点击运行按钮(或按F5键),程序便开始启动。启动画面如下:
图1 启动界面
点击“进入”即可进入选择梁的类型界面,在此界面中,使用者根据实际情况选择要研究的梁的类型,点击即可进入相应梁的计算界面。例如想要计算双外伸梁,则点击“6、双外伸梁”即可进入计算界面,若想返回开始界面,则点击“返回开始界面”即可。
图2 梁的选择界面
图3 梁的计算界面
此程序可以计算梁在集中力、均布力和集中力偶的作用下梁的剪力和弯矩,并求出剪力的最大值和弯矩的最大值。以双外伸梁为例,对照左侧参数输入提示,在相应文本框里输入梁的基本参数,如弹性模量E、长度L,和载荷大小及位置,如均布力q、均布力起始位置b1、结束位置b2。输入完毕后点击“计算”按钮,在作图框内便显示出梁的剪力和弯矩图和最大值点,在结果文本框内便得出相应最大值和最大值所在位置。若要改变参数,先点击“清除”按钮,使做图框和结果文本框初始化,再更改相应参数,再次点击“计算”。
三、程序设计过程
以左固定端悬臂梁为例,首先选取坐标系,确定载荷大小、类型和位置坐标,然后分别计算单个载荷所对应的支反力和力矩,用公式计算位置x处对应的剪力和弯矩值,最后把各个载荷产生的在位置x处的剪力和弯矩值相加,便得出总的
剪力和弯矩值。要注意的是,集中力和均布力取向下为正,外力偶取逆时针为正。所用公式如下:
图4 左固定端悬臂梁计算示意图
设F产生的支反力为FOy1,力偶为MO1,对应的剪力为Fsx1,弯矩为Mx1;q产生的支反力为FOy2,力偶为MO2,对应的剪力为Fsx2,弯矩为Mx2;M产生的支反力为FOy3,力偶为MO3,对应的剪力为Fsx3,弯矩为Mx3。则: FOy1=F;
MO1=FOy1*a; FOy2=q*(b2-b1);
MO2=q*(b2-b1)*(b2+b1)/2; FOy3=0; MO3=M; 对于F:
当x<=a时, Fsx1=-FOy1;
Mx1=FOy1*x-MO1; 当a 当x<=b1时 Fsx2=-FOy2; Mx2=FOy2*x-MO2; 当b1 Fsx2=-FOy2 + q*(x-b1); Mx2(ff)=FOy2*x-MO2-(x-b1)^2*q/2; 当b2 Mx2=0; 对于M: 当x<=c时 Fsx3=0; Mx3=M; 当c 最后,设合剪力为Fsx,合弯矩为Mx,则: Fsx=Fsx1+Fsx2+Fsx3; Mx=Mx1+Mx2+Mx3; 对应程序如下所示: E=10^9*str2double(get(handles.edit1,'String')); L=str2double(get(handles.edit2,'String')); F=str2double(get(handles.edit3,'String')); a=str2double(get(handles.edit4,'String')); q=str2double(get(handles.edit5,'String'));

FOy2=q*(b2-b1); MO2=q*(b2-b1)*(b2+b1)/2; FOy3=0; MO3=M; leng=length(x); xx1=round(a/L*leng); xx21=round(b1/L*leng); xx22=round(b2/L*leng); xx3=round(c/L*leng); for ii=1:leng if ii<=xx1 Fsx1(ii)=-FOy1; Mx1(ii)=FOy1*(ii-1)*L/500-MO1; else Fsx1(ii)=0; Mx1(ii)=0; end end for ff=1:leng if ff<=xx21 Fsx2(ff)=-FOy2; Mx2(ff)=FOy2*(ff-1)*L/500-MO2; else if ff<=xx22 Fsx2(ff)=-FOy2 + q*((ff-1)*L/500-b1); Mx2(ff)=FOy2*(ff-1)*L/500-MO2-((ff-1)*L/500-b1)^2*q/2; else Fsx2(ff)=0; Mx2(ff)=0; end end end for pp=1:leng if pp<=xx3; Fsx3(pp)=0; Mx3(pp)=M; else Fsx3(pp)=0; Mx3(pp)=0; end end flag1=1; flag2=1; Fsx=Fsx3+Fsx2+Fsx1; Mx=Mx3+Mx2+Mx1; for jj=1:leng if abs(Fsx(jj))>=abs(Fsx(flag1)) flag1=jj; end if abs(Mx(jj))>=abs(Mx(flag2)) flag2=jj; end end yy=0*ones(1,leng); yyy2=abs(Fsx); yyyy2=max(yyy2); yyy3=abs(Mx); yyyy3=max(yyy3); axes(handles.axes2); grid on plot(x,yy,'LineWidth',2); axis([0,L,-2*yyyy2,2*yyyy2]); hold on plot(x,Fsx,'LineWidth',2); hold on xxx1=L/500*(flag1-1); plot(xxx1,Fsx(flag1),'bo','MarkerSize',10); hold on for kk=1:4:leng plot([x(kk),x(kk)],[0,Fsx(kk)],'LineWidth',0.4) end xlabel('x/m'); ylabel('??á|Fs/N'); axes(handles.axes3); grid on plot(x,yy,'LineWidth',2); axis([0,L,-1.2*yyyy3,1.2*yyyy3]); hold on plot(x,Mx,'LineWidth',2); hold on xxx2=L/500*(flag2-1); plot(xxx2,Mx(flag2),'bo','MarkerSize',10); for ll=1:4:leng plot([x(ll),x(ll)],[0,Mx(ll)],'LineWidth',0.4) end str1=num2str(yyyy2); str2=num2str(xxx1); set(handles.edit10,'String',str1); set(handles.edit11,'String',str2); str3=num2str(yyyy3); str4=num2str(xxx2); set(handles.edit12,'String',str3); set(handles.edit13,'String',str4); 从程序文本框中输入参数值,输入完毕后点击“计算”按钮,在作图框内便显示出梁的剪力和弯矩图和最大值点,在结果文本框内便得出相应最大值和最大值所在位置。 其他梁的程序设计过程也如此,这里不再叙述 四、程序算例 下面给出各个梁的算例。 1、左固定端悬臂梁计算例题 例1.有一左固定端悬臂梁长l=4m,在梁中间作用有集中力P=4N,梁右端作用有集中力偶m=5N·m,左端作用均布载荷,载荷集度q=2N/m,作用图示如下。请作出梁的剪力弯矩图,并求出剪力弯矩的最大值与其出现位置。 计算结果: 图5 计算结果截图 根据题意可得FA=8N,MB=7N·m,将梁分为AC、BC段进行分析,即可作出梁的剪力、弯矩图,所作图形与程序所作结果相同。从剪力、弯矩图上显然可以看出剪力最大值Fmax=8N,弯矩最大值Mz=7N·m,均与程序相同,故此段程序编写正确。 2、右固定端悬臂梁计算例题 例2.有一右固定端悬臂梁长l=2m,在梁中间作用有集中力F=5N,梁右端作用竖直向下的集中力P,大小为5N,在梁的0.5m到1.5m作用有均布载荷,载荷集度为q=2N/m,梁左端作用有顺时针集中力偶m=10N·m,作用图示如下。请作出梁的剪力弯矩图,并求出剪力弯矩的最大值与其出现位置。 计算结果: 根据题意可得FB=7N,MA=5N·m,将梁分为AD、DC、CE、EB段进行分析即可作出梁的剪力弯矩图,所作图形与程序结果相同。从剪力、弯矩图上显然可以 看出剪力最大值Fmax=7N(出现在EB段,本段程序显示结果在E截面处),弯矩最大值Mz=5N·m(出现在AD段,本段程序显示结果在A截面处),均与程序相同,故此段程序编写正确。 图6 计算结果截图 3、简支梁计算例题 例3. 已知一横梁长l=4m,两端铰支。现在x=2m处作用一大小为4N、方向竖直向下的集中力,并且在整根梁上作用有竖直向下的均布载荷,大小为q=2N/m,作用示意图如下。试做出梁上的剪力和弯矩图,并求出剪力弯矩的最大、最小值及它们出现的位置。 计算结果: 求支反力得FA=6N,FB=6N,作梁的剪力弯矩图与程序所作结果相同,从剪力弯矩图上显然可以得到剪力最大值Fmax=6N,弯矩最大值Mz=8N·m,与程序相同。理论计算绘制图示上可以看出剪力最大值在梁的左右两端点处取到(x=0和x=4m处),程序中只显示了一个(x=4m处)。 图7 计算结果截图 4、左外伸梁计算例题 例4. 已知一左外伸梁长3m,可动铰支座距左端面1m,在x=2m处作用一大小为P=10N,方向竖直向下的集中力,图形如下。试做出梁上的剪力和弯矩图,并求出剪力弯矩的最大、最小值及它们出现的位置。 计算结果: 图8 计算结果截图 求支反力得FA=2.5N FB=7.5N,作梁的剪力弯矩图与程序所作结果基本相 同(程序所作剪力弯矩图中有断点存在,这是由于本程序绘制剪力弯矩图采用的是散点法,当剪力弯矩值有突变时程序计算的因数值不连续而产生“跳跃”现象),从剪力弯矩图上显然可以得到剪力最大值Fmax=7.5N,弯矩最大值Mz=7.5N·m,与程序相同。 5、右外伸梁计算例题 例5. 已知一右外伸梁长1.5米,右支点距右端面0.5米,在两支架中间作用一大小为P=5N,方向竖直向上的集中力,图形如下,试做出梁上的剪力和弯矩图,并求出剪力弯矩的最大、最小值及它们出现的位置。 计算结果: 图9 计算结果截图 求支反力得FA=2.5N FB=2.5N,作梁的剪力弯矩图与程序所作结果相同(程序所作剪力弯矩图中有断点存在,这是由于本程序绘制剪力弯矩图采用的是散点法,当剪力弯矩值有突变时程序计算的因数值不连续而产生“跳跃”现象),从剪力弯矩图上显然可以得到剪力最大值Fmax=2.5N,弯矩最大值Mz=1.25N·m,与程序计算结果相同。理论计算绘制图示上可以看出剪力和弯矩最大值应该在x=0.5m处取到,而程序计算的最大值分别在x=0.999m和x=0.501m取到,这是由于在程序编写过程中把梁在集中作用出分成了两段,集中力作用以左部分所有的x都小于0.5m,集中力作用以右部分所有x都大于0.5m,因而显示结果会出现与理论计算的微小差别。 6、双外伸梁计算例题 例6. 已知一双外伸梁长4米,固定铰支座距左端面1m,可动铰支座距右端面1m,在距离梁的左端0.5m处作用一大小为F=4N、方向竖直向下的集中力,两铰支座之间作用有向下的均布载荷,大小为2N/m,图形如下。试做出梁上的剪力和弯矩图,并求出剪力弯矩的最大、最小值及它们出现的位置。 计算结果: 求支反力得FA=1N FB=7N,作梁的剪力弯矩图与程序所作结果相同(程序所作剪力图中有断点存在,这是由于本程序绘制剪力弯矩图采用的是散点法,当剪力弯矩值有突变时程序计算的因数值不连续而产生“跳跃”现象),从剪力弯矩图上显然可以得到剪力最大值Fmax=4N,弯矩最大值Mz=-2N·m,与程序计算结果相同。理论计算绘制图示上可以看出剪力和弯矩最大值分别在x=0.5mx=1m处取得,与程序计算结果也相同,因而此段程序运行正确。 图10 计算结果截图 五、程序缺陷 由于本程序绘制剪力弯矩图采用的是散点法,因而在剪力或弯矩有突变时图示上会产生断点,未连接上。可以采用“line”指令,在数据有突变时直接直线连接。 六、体会与收获 在这次上机编程作业中,我虽然花费了很长时间,但是收获很多。在此过程中,我对MATLAB语言有了更加熟悉的运用,这将成为我一生的财富,MATLAB也必将成为我日后学习工作的强大工具。在看到自己做出的最终结果以及它运行时的高效、简洁,我不禁有了一丝成就感。我为能有一次这样锻炼的机会而感到幸 运,希望以后还会更多这样的机会充实自己。对于材料力学这门课程,我想也会因为这次程序的编写而记忆的更加深刻,我一定要争取多掌握一些这方面的知识,然后在工作中充分的应用进去! 当然,作为初学者,制作出的软件不免瑕疵很多,还烦请老师批评指正。但我相信,在今后的学习中,我对MATLAB的应用能力会愈加娴熟。 七、程序源代码 1.左悬臂梁的源程序 E=getappdata(BianXing_ZuoGuDingDuan,'E');
