T=T1+T2 →→→→→0.78=0.7+0.08 在一个大周期内分为了两个小周期. T1内: clear all; v_1=0:0.01:0.7; y_1=(0.00057*exp(v_1/sqrt(0.24/9.81))/sqrt(0.24/9.81)+0.0206*exp(-v_1/sqrt(0.24/9.81))/sqrt(0.24/9.81))+0.06/0.7; plot(v_1,y_1)图像为: T2内: v_2=0.7:0.00114:0.78; y_2=0.41*cos((v_2-0.86)/(sqrt(0.24/9.81)))+(0.34/sqrt(0.24/9.81))*sin((v_2-0.86)/sqrt(0.24/9.81)); plot(v_2,y_2)图像为: 单周期T内: clear all; v_1=0:0.01:0.7; v_2=0.7:0.00114:0.78; y_1=(0.00057*exp(v_1/sqrt(0.24/9.81))/sqrt(0.24/9.81)+0.0206*exp(-v_1/sqrt(0.24/9.81))/sqrt(0.24/9.81))+0.06/0.7; y_2=0.41*cos((v_2-0.86)/(sqrt(0.24/9.81)))+(0.34/sqrt(0.24/9.81))*sin((v_2-0.86)/sqrt(0.24/9.81)); plot(v_1,y_1) plot(v_2,y_2) s=[y_1 y_2]; v=[v_1 v_2]; plot(v,s)图像为: 用矩阵,执行一次储存一次,并设置好变量长度 clear all; v_1=0:0.01:0.7; v_2=0.7:0.00114:0.78; y_1=(0.00057*exp(v_1/sqrt(0.24/9.81))/sqrt(0.24/9.81)+0.0206*exp(-v_1/sqrt(0.24/9.81))/sqrt(0.24/9.81))+0.06/0.7; y_2=0.41*cos((v_2-0.86)/(sqrt(0.24/9.81)))+(0.34/sqrt(0.24/9.81))*sin((v_2-0.86)/sqrt(0.24/9.81)); plot(v_1,y_1) plot(v_2,y_2) s=[y_1 y_2]; v=[v_1 v_2]; plot(v,s) y=[]; x=[v]; for i=1:4 y=[y s]; end for j=1:3 v1=0.78*j+v_1; v2=0.78*j+v_2; x=[x v1 v2]; end plot(x,y)三周期图像如图
