6. Main design requirements of Bridge Girder Erection Machine for High Speed Railway
● Technical index；
Safety factor 1.5
Using grade： U3
Load state： moderate
Working grade of the whole machine： A3
Working grade of the mechanism：M4
Working condition and requirements of design etc.
● Calculation analysis and check-calculation of the whole structure According to technology condition of design of crane, we confirm the construction condition, and then calculate and analyze the strength, stiffness and stability.
After the classical calculation, we start the calculating work of design of steel structure, and adopt the finite element analysis, the load applied to models respectively, and then calculating and analyzing beam element and plate element. Finally, the authoritative department will check and calculate again.
