Homework Help: Static analysis with Femap Software

  1. Oct 29, 2008 #1
    1. The problem statement, all variables and given/known data
    EOT Crane - Double Girder
    Main capacity : 80,000 Kg
    Aux. Capacity : 20,000 Kg
    Span : 22,000 mm
    Crab Weight : 6,000 Kg
    Deflection : 22,00 mm
    Density : 0.0078
    q : 4.1808 Kg/cm
    Netto(q) : 4.719
    Modulus Section (Wx) = 29064.715 [cm][/3]
    Modulus Section (Wy) = 9675.54[cm][/3]
    Moment inertia :
    - Ixo = 546226.67 [cm][/4]
    - Ix = 2383306.67 [cm][/4] (What's it?? Any body knows??)
    - Iyo = 114346.99 [cm][/4]
    - Iy = 33643.95 [cm][/4] (What's it?? Any body knows??)
    My design is want to put the load around the top of surface.

    I am sorry if my english is not good and maybe makes you a little confused. o:)

    Question :
    1. Totall moment = ?? (M = Mp+Mq)
    2. Totall stress = ?? (Stress totall = Totall Stress x^2 + Totall stress y^2)
    3. Total Deflection = ?? (Ft = Fp + Fq)
    4. Frecuency = ?? {Fr = (1/2 phi) x (g/Ft)

    My question are:
    1. Does anybody have done this problem before?? (Any reference)
    2. I know the stress equation is f=P.A (P=stress)
    The totall stress???
    3. I put the load is 86,000 Kg, don't I put a wrong load?
    4. I still confused about p & q, what are they mean?
    5. I want to put the data in Femap software with 3D model (Any suggestion for better analysis)??
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution
