箱梁张拉油表读数计算
一、1#千斤顶1500KN 表1088
①X =1395⨯140
1000×4=781.2KN
Y =0.034X+0.5035=0.034×781.2+0.5035=27.064Mpa 20%时,X =781.2×0.2=156.24KN
Y =5.816Mpa
②X =1395⨯140
1000×3=585.9KN
Y =0.34X +0.5035=0.034×585.9+0.5305=20.424Mpa 20%时,X =85.9×0.2=117.18KN
Y =4.49Mpa
二、2#千斤顶1500KN 表1082
①X =781.2KN (4孔)
Y =0.0341X +1.0713=27.71Mpa
20%时,X =156.24KN
Y =6.4Mpa
②X =585.9KN (3孔)
Y =0.0341X +1.0713=21.05Mpa
20%时,X =117.18KN
Y =5.067Mpa
三、3#千斤顶1500KN 表1086
①X =781.2KN (4孔)
Y =0.0332X+0.2874=26.223Mpa 20%时,X =156.24KN
Y =5.475Mpa
②X =585.9KN (3孔) Y =19.74Mpa
20%时,X =117.18KN
Y =4.18Mpa
四、4#千斤顶1500KN 表1057 ①X =781.2KN (4孔)
Y =0.0327X +0.702=26.247 Mpa 20%时,X =156.24KN
Y =5.81Mpa
②X =585.9KN (3孔) Y =19.86Mpa
20%时,X =117.18KN
Y =4.53Mpa
