十字轴
1.
The internal cause was stress concen tration in its spider chamer rough su rface and the crack between its base ma-terial and hardened surface existed in chamfer area;after the surface la yer carburization and hardening the chamfer surface was very brittle and because of material impurit.
通过对宝钢钢包台车万向轴断裂断口、材料理化性能、疲劳强度等分析,指出了万向轴断裂的内因为十字轴轴承的台阶R角加工粗糙,产生应力集中;R角表面经过渗碳处理渗层,使其脆性增大;R角处渗层与基体的过渡层中存在着裂纹;十字轴的夹杂物较多,冲击值低;外因为恶劣的使用环境和不良操作习惯。
2.

通过扫描电镜观察、金相检验、化学分析以及硬度检测等手段,对中厚板轧机传动部位的十字接轴断裂的原因进行了分析,发现轴根部存在渗碳层并且变截面处圆角较小、表面加工较粗糙。
补充资料:双十字相乘

双十字相乘

分解形如axx+bxy+cyy+dx+ey+f 的二次六项式

在草稿纸上,将a分解成mn乘积作为一列,c分解成pq乘积作为第二列,f分解成jk乘积作为第三列,如果mq+np=b,pk+qj=e,mk+nj=d,即第1,2列和第2,3列都满足十字相乘规则。则原式=(mx+py+j)(nx+qy+k)

例:3xx+5xy-2yy+x+9y-4=(x+2y-1)(3x-y+4)

因为3=1×3,-2=2×(-1),-4=(-1)×4,

而1×(-1)+3×2=5,2×4+(-1)(-1)=9,1×4+3×(-1)=1
