Study On Rapid Design Of Skid Structure Based On CAD/CAE

With the energy shortage, the competition in the petroleum exploitation becomesmore and more fierce. The petroleum equipment played a key role in the petroleumprospecting and exploitation. However, compared with other countries, the equipmentin China was lag behind. According to this, we brought forward the modern designtheory to improve the technology and the standard of petroleum exploitation in China.According to the structure, the skids were divided into different sorts. TheExplosion-proof Heater Skid was taken as example to analyze the structure. Using themodular design method, the skid was divided into four function modules. These fourparts were modularized and fixed into a whole entity module using the SolidWorks,which was a three-dimensional software. Based on these four solid modelssimplification, finite element models were established. And the static characteristicsof the structures were calculated with finite element analysis softwareCOSMOSWorks. In satisfying the structure intensity and stiffness, the premise movesdownwards, according to the principle saving material and reducing structuremass .We optimized the comprehensive support, which was an important supportingmember in the skid. We also took the reanalysis, and got the loading capacity afteroptimization.This research on the skid provided theoretical basis for structureoptimization.This structure design in the Explosion-proof Heater Skid confirmed thefeasibility and advantage of CAD/CAE in the sea petroleum explosion. We alsosummarized a set of rules in the mechanical structure design, which provided valuableinformation to the large-scale complex structure design, optimization andmodification in the sea platform.
