Project description:
A specialist in VAT calculations is needed. It is necessary to calculate the VAT of the RVSP 20000 tank with the Diogene operating URDO to assess the change in the stress-strain state of the reservoir when exposed to bottom sediment washing devices.
There is a detailed method of this calculation.
Background:
Device of washing of bottom sediments (RDO) "Diogenes" in the lower belt of the tank on the cover of the oval hatch of the laze 600x900 mm;
TWSP reservoir 20000;
The height of the tank wall Hst = 11.94 m, the diameter of the tank D = 45.6 m, the number of belts - 8;
The height of the oil spill under operating conditions Hvzl = 10.03 m;
The height of the belts hi = 1.5 m;
Thickness of belts: 1 belt - 13 mm, 2, 3,4 ,5, 6, 7, 8 belts - 12 mm;
Steel 09G2C
Endurance Limit 245 MPa
The yield limit is 290 MPa
The density of steel ρst = 7850 kg / m3;
The density of raw materials ρ = 872 kg/m3;
The steel elasticity module E = 206000 MPa;
Acceleration of free fall g = 9.8 m/s2
Poisson coefficient 0.3
The height of the roof of the tank hk = 4.0 m
Loads:
Pressure from weight of oil (hydrostatic load) 85712.37 Pa
Weight of URDO "Diogenes" 400 kg
Reactive repulsion caused by the operation of the drive shaft with the propeller at the maximum power of the Diogen URDO - 4000N
Moment of the action of weight of URDO "Diogenes" - 1920 N*m
Required results:
Photo of the calculation scheme
(2) Photo of the deformation scheme and the current equivalent stresses in the metal structure of the tank during the operation of the ORDO
3) The value of the maximum equivalent wall stresses (to be obtained within 250-475 MPa) (without first belt gain)
(4) Maximum displacement value (to be approximately 0.0499 m) (without first belt reinforcement)
