optimization of pressure vessel design

Master Of Technology that is what you wish to be?

Well Be Just That. Your Own Master!

And be in full control of your life and duties as a safe, optimum designer .

In the hypocritic money-driven real world of Government,Commerce and Industry.

Ask yourself these:

Did Newton,Pascal,Einstein, Steinmetz-- have access to Websites,Algorithms,CR4?

Did you go through Classic Text books the last 4-5 years telling about Hoop Stress, Triaxial stress analysis, Strengths of Steel plates ,Temp. Relationship on Yield/UTS,Commercial availability/price of plain- Carbon, Alloyed, Stainless steels , Weldability, Corrosion .If you use all these you come to Yield point thickness say 11.3mm,Plasticlimit say 9.1mm. Now you will need to decide Factor of Safety (euphemism= Redundancy) (Factor of Ignorance). Say you come to 16mm for plain carbon 0.25%"Boiler Quality"-- would your Ambani Malik Trust you - or will he call in Bechtel for a Billion Dollar "Package Deal" with some Delhi officer ALLOWING?

Did you make serious effort to Learn and Master all you were told to learn? If you Brushed these aside ,hoping some Software will always available somebody guided you wrong-

There is Still time Brother!

Optimization is all in your using what you were supposed to Learn!

The purpose of your project is to give you some experience in the application of what you have learned (the level of your knowledge is unknown). This post will only outline the steps you need to consider for creating software optimization / design tool..

Note:

It is assumed that you have some programming skills.

My knowledge of these vessels is limited.

Step 1

Relevant data sheets must be encapsulated into lookup tables.

A function must be created for every relevant formula.

A function is a computer subroutine returning a result for the entered parameters.

Step 2 Requirements input

Create an input screen for the variable parameters required including:

Volume, shape , inlet, outlet, inspection and cleaning hatches, Pressure (max, working etc), gas or fluid. (here you must apply your knowledge and mind)

Step 3 Select material

The material use must be capable of withstanding the gas/fluid and the environment.

Example: aqua lungs

Step 4 Select and calculate.

You could start mid range and iterate to the correct spot or start at the smallest and increase until the correct size is found.

Example: to calculate the desired wall thickness: start with the thinnest plate (say 1mm)

If it cannot handle the pressure increase to the next thickness (say 1.2mm)

Keep on increasing until it can withstand the pressure (including safety margin)

The welding or flanges must also be calculated.

Step 5 continue calculations

Design other parts. For example the bolts on the cleaning hatch.

Step 6 Refine choice

Refine on economical, financial, safety or other grounds.

Step 6 – data sheet

Prepare a printed hard copy of your Input, calculations and results.

Step 7 Prepare instruction manual.

Step 8 Hand in an await marks.
