Simulation Software

I have neither time nor inclination to go deeper. HERE are some links for you as a starter.

Josh, Lyn, Bruce.,

thanks for your replies and i really admire it. I am now actually working as an assitant electrician on board the ship. this is why I need some basic ideas on troubleshooting techniques for ship's crane, motor controller circuit, and the like where most of the cases are ship electrical systems troubleshooting.

am a registered master electrician by profession at the moment.

Once again, thanks for your help and please keep in touch as well. if you have some e-books or whatever.

Cheers!

Have you checked with the crane manufacturer?

What is an industrial circuit?

I don't know if this is a work question or a homework question by RME who graduates in 2012.

I do NOT have qualifications in this area but I'll put my 2 cents worth in anyway. I would guess that the first and necessary step is to have an accurate block diagram of the control, electrical power, hydraulic and mechanical sub systems that match your crane.

For TROUBLESHOOTING my guess is that software would only typically be used to communicate with control items.

For DESIGN or HOMEWORK my guess is that more than one software package would typically be used based upon the item of interest in the block diagram. Circuit simulation might be done with SPICE or a similar package. Mechanical, hydraulic and thermal might be addressed with SolidWorks, ProE or similar.

When things don't go well with a crane people tend to end up dead. Thus, I hope this is a homework question.

One could simulate a combination of electrical control/hydraulic (or mechanical) systems using Scicos (or Xcos), which are part of the Scilab Open Source project (depending on which version of Scilab one is using). Of course, this is NOT an approach that one is going to master in the time frame normally available for a single semester course, unless one has worked with this sort of simulation in the past...
