Dear ANSYS Team, 

I am reaching out with a general inquiry, as my searches so far have not yielded clear information on a specific application scenario. My experience with ANSYS has been limited to simulations in structural mechanics and explicit dynamics. Now, I am faced with a new challenge and am seeking to determine if ANSYS is suitable for simulating the following scenario: I plan to simulate two cars traveling at the same speed, where one of the cars is equipped with an electromagnet aiming to attract the other vehicle. The target vehicle has a total weight of 1600 kg, with 260 kg of that being steel in the bodywork, which is the component that can be influenced by the electromagnet. Additionally, this car has a contact area of 800 cm², resulting in a contact pressure of 196200 Pa.

For the simulation, I am interested in determining specific parameters of the electromagnet to analyze the efficiency and feasibility of the described scenario. Specifically, I am looking to understand the following values:

• The required current intensity,
•  The necessary voltage,
•  The optimal size and number of windings of the electromagnet.

 

Is ANSYS capable of conducting such an analysis? Could you also inform me about which modules or tools within ANSYS would be most suited for this type of electromagnetic interaction simulation? Any guidance or recommendations on how to approach this project would be greatly appreciated.

Thank you in advance for your support and advice. 

Best regards,

Jackely

It sounds like you would want to use Maxwell, which is part of the Ansys Electromagnetics Suite. This post is listed under the "General Mechanical" category, and I don't see a way to change that. It is probably best if you submit a new post in the electromagnetics or Maxwell category.

I don't know where you came up with the contact pressure value of 196200 Pa. It seems like the idea is to connect with another car and then slow it down, such as a police car scheme to capture a chase vehicle. You would need to specify a maximum acceleration value to come up with a max contact pressure that you would assume the magnet could exert.

In Maxwell, you would apply excitation as either current or voltage, so you can't solve for both of them unless you take a guess at one. Given that you also don't know the size and windings, it sounds like you need to do an optmization study for varying parameters. Optimetrics is part of Maxwell.

Resubmit this post in the electromagnetics category to get more specific answers in that area.

Note: you can get force generated on bodies in Maxwell as an output parameter.

Hello Jakely,

       What kind of equipment or process will you want to simulate or design? linear motor or something else? 

       If it is a motor, Yes, Maxwell is a suitable tool.
