CEPC探測(cè)器三維磁場(chǎng)和鐵軛受力計(jì)算PPT課件

1、1CEPCCEPC探測(cè)器三維磁場(chǎng)和鐵軛受力計(jì)算探測(cè)器三維磁場(chǎng)和鐵軛受力計(jì)算由于模型復(fù)雜，故先模糊部分細(xì)節(jié)，將桶軛建為一體，找尋所受電磁力最大的位置。再將該位置結(jié)構(gòu)細(xì)化，計(jì)算其所受電磁力。如左圖所示，桶軛上所受電磁力最大的位置位于更靠近對(duì)稱面的內(nèi)側(cè)。故在此位置建立一組分體鐵軛如下圖。2CEPCCEPC探測(cè)器三維磁場(chǎng)和鐵軛受力計(jì)算探測(cè)器三維磁場(chǎng)和鐵軛受力計(jì)算Summary force of barrelyoke (N)barrelyokeX AxisY AxisZAxis1-1.06E+04-4.60E+053.20E+0425.80E+021.36E+051.74E+0434.40E+021.3
