A structural analysis was performed on the Exhaust Stack of SmA Gas Turbine
Generator to evaluate the strength and stability of the part while lifting and
it should fulfil the requirement criteria outlined in Ref. [S1], Ref. [S2] and Ref. [S3].
Ref. [S1], Ref. [S2] and Ref. [S3].
Material Name: ASTM A 240 Stainless Steel Type 316/316L
All parts in the FE model have the same materials properties
Results displayed are based on 4g consideration
Maximum sling tension calculation
S1 - lifting (example for 6G)
The table shows the maximum tension sling is 148220.09N
Minimum required lifting capacity of the sling 148220.09N = 15.11 tonnes
Selected shackle: G-2130, Bolt type anchor shackle
with 1.5" nominal size and load limit of 17 tonnes
Scaffolding is considered one of the most essential parts in building construction, allowing a support structure to be erected quickly. Finite Element Analysis (FEA) can be adopted in order to validate the strength and stability of the said scaffolding. The following load cases can be done using FEA
Linear Static Analysis can be used to analyze the linear stress and strain when subjected to weight of the worker and their tools.
Linear Buckling Analysis is the analysis used to predict the load level, when applied will cause a sudden loss in stiffness; sudden large increment of displacement at the said load.
The critical area seems to rely on the T joint of the scaffolding structure with a value of 430 Mpa.
4 tier seems to have a similar stress distribution, but with slightly higher maximum stress at T-joint
Linear reluctant maximum stress is less than 1% difference between 2 tier and 4 tier scaffolding
Linear buckling analysis, when conducted to both assy shows a significant difference of about 40% in terms of loading before buckling was predicted. This analysis can be further refined using Non-Linear Buckling Analysis, in which the loading is applied at a small rate until buckling happens but it shall require a more computational power
Full open = 50mm
Current open = 37mm (74%)
Q is the rate of flow (expressed in US gallon per minutes)
SG is the specific gravity of the fluid (for water = 1);
ΔP is the pressure drop accross the valve (expressed in psi)
Flow coefficient, Cv value is obtained
