[求助]急求人工神经网络在加速寿命试验中应用的MATLAB仿真程序
<P > </P><P >数据如下：</P>
<P >在一批电机中随机抽取<FONT face="Times New Roman">40</FONT>部，然后分四组。分别在<FONT face="Times New Roman">190</FONT>℃，<FONT face="Times New Roman">220</FONT>℃，<FONT face="Times New Roman">240</FONT>℃，<FONT face="Times New Roman">260</FONT>℃下作高温存储试验。实验如表：</P>
<P ><FONT face="Times New Roman">j T1jT2j T3jT4j</FONT></P>
<P ><FONT face="Times New Roman">1 3610 1764 1175 600</FONT></P>

<P ><FONT face="Times New Roman">7 6367 2887 1665 1320</FONT></P>
<P ><FONT face="Times New Roman">8 7050 3108 1713 1464</FONT></P>
<P ><FONT face="Times New Roman">9 7711 3108 1761 1608</FONT></P>
<P ><FONT face="Times New Roman">10 8550 3406 1953 1896</FONT></P>
<P ><FONT face="Times New Roman"> <p></p></FONT></P>
<P >得出的可靠性寿命结果</P>
<P ><FONT face="Times New Roman">ti 463K 493K 513K 533K</FONT></P>
<P ><FONT face="Times New Roman">t0.5,i 5900 2600 1600 1040</FONT></P>
<P ><FONT face="Times New Roman">lg t0.5,i 3.770852 3.4149333.204120 3.017033</FONT></P>
<P ><FONT face="Times New Roman">σi 0.137633 0.1035410.0791810.226005</FONT></P>
<P ><FONT face="Times New Roman">10<SUP>4</SUP>/T<SUB>i </SUB>21.6 20.28 19.49 18.76</FONT></P>
<P >利用<FONT face="Times New Roman">ti</FONT>和<FONT face="Times New Roman">10<SUP>4</SUP>/T<SUB>i</SUB></FONT>成线形关系</P>
<P >最后可得出<FONT face="Times New Roman">T0=50</FONT>℃，即<FONT face="Times New Roman">K=323k</FONT>，<FONT face="Times New Roman">10<SUP>4</SUP>/T<SUB>i</SUB>=30.96</FONT>下的可靠性特征：</P>
<P ><FONT face="Times New Roman"> t0.5,0=1.78*10<SUP>6</SUP></FONT>小时</P>
<P ><FONT face="Times New Roman">σ0=(σ1+σ2+σ3+σ4)/4=0.136590</FONT></P>
<P >通过试验数据的前三组进行训练，后三组进行测试，最后得出可靠性特征。</P>
<P >求求各位高手帮帮忙。。</P>
