非线性支承转子系统分岔图,求教,指点迷津


参考别人论文里面的程序绘制的分岔图,是什么原因?

%非线性弹性支承转子系统function dy=diffequat1(t,y)global theta e kz k w W r2 M m g D beta;e=0.0002;theta=1.415263;r2=1000.00;w=0.25;W=500;kz=19304448;M=50;m=10;D=0.008;g=9.800;k=1930444.8;beta=1;dy=e*kz/M/g*cos(t-theta)-r2*kz*w^2/M/g*sin(theta)-kz/M/W^2*cos(theta)-2*D*(kz/M)^0.5/W*(y(2)-y(4))-kz/M/W^2*(y(1)-y(3));y(4);-r2*kz*w^2/W^2/m/g*sin(theta)-kz/m/W^2*cos(theta)+2*D*M*(kz/M)^0.5/W/m*(y(2)-y(4))+kz/m/W^2*(y(1)-y(3))-2*D*M*(kz/M)^0.5/W/m*y(4)-k/m/W^2*y(3)-beta*k/m/W^2*y(3)^3;y(6);e*kz/M/g*sin(t-theta)-r2*kz*w^2/M/g*cos(theta)-kz/M/W^2*cos(theta)-2*D*(kz/M)^0.5/W*(y(6)-y(8))-kz/M/W^2*(y(5)-y(7));y(8);-r2*kz*w^2/W^2/m/g*cos(theta)-kz/m/W^2*sin(theta)+2*D*M*(kz/M)^0.5/W/m*(y(6)-y(8))+kz/m/W^2*(y(5)-y(7))-2*D*M*(kz/M)^0.5/W/m*y(8)-k/m/W^2*y(7)-beta*k/m/W^2*y(7)^3];

绘制分岔图程序:
clear all;
clc;
W=100:10:1300;
for h=1:length(W)
T=2pi;
=ode45(‘diffequat1’,,),[],W(h));
plot(W(h),x(80000:100:end,1),’k.’);
hold on;
end
绘制的图出来感觉是不对的。

看不到图?
难道是网速的原因
