Title: Problem with modeling of Wind Turbine in VHDL-AMS
Post by Mils on Jul 22^nd, 2010, 1:38am

Hey All,

Presently I am handling a very peculiar problem. Actually I am trying to create a Aerodynamic model of Wind Turbine in VHDL-AMS.

While working in Mechanical domain, I always have a problems with references. because it's a 3 dimmentional system, rotating system. How can we define 3 references in 3 different directions and how can we set up a relationship between these these references ? does any body worked/work on similar kind of problem. please let me know.

more specifically, does any body simulated a force/any vector which has constant magnitude but rotating in nature. please let me know.

thanks and regards,

Mils.

Hi Mils,

With respect to ground:
one can use rotational_ground, translational_ground, electrical_ground, etc.

I have simulated mechanical systems with beams and rigid bodies in VHDL-AMS, so should be able to help you with your other questions,
but do not fully understand what you are trying to achieve. Please explain.

Best regards,

Richard

Hi,
The VHDL-AMS standard defines different disciplines such as electrical, rotational, ...
In each of them the duality between the "across" and the "through" quantities defining this very discipline is defined. These are for the electrical discipline respectively the voltage and the current. For the rotational, these are the angle and the torque.

Taking advantage of these disciplines, describing a mechanical is quite staight forward (from a language point of view at least ;-))

Cheers,
Jerome

Hi again,

May I ask you in which kind of activities do you aim to model such a system?

Thanks,
Cheers Jerome
