How to Simulate Moving Loads in Ansys 15?

AI Thread Summary
To simulate moving loads in ANSYS 15, a user is exploring the possibility of modeling a pulley load moving over a steel rope. They suggest using a contact surface between the rope and pulley, applying the pulley’s mass as the load, and considering a velocity for the pulley. The user inquires about the feasibility of using Transient Structural analysis for this scenario. While some participants question the need for simulation over analytical methods, the user emphasizes the complexity of their actual problem, which involves intricate structures and damping. They seek guidance on a more efficient simulation approach rather than applying loads at multiple intervals.

Hi,

I am trying to simulate a moving load in ansys 15. Could anybody guide me on how I could do it?
A typical example:
Calculating stress across a steel Rope ( assume solid circular c/s) between point A to B while a pulley load moves over it between the 2 points with a certain velocity.

I will be modelling the actual problem in 3D and importing the geometry. My initial thought was to add contact surface between the rope and the Pulley with the mass of the pulley as the load itself and then apply a velocity to the pulley.

Can I use Transient structural for this?

please help.

Why are you simulating this on ANSYS? Wouldn't simple analytical formulas be sufficient for you?

How do you plan to provide material properties for the rope? Do you have any reference paper etc?
Please provide links if any
 
Hello RDK,
As I mentioned, That was an example scenario. I need to know if you can simulate moving loads on a structure.
as for the Material properties, yes, It will be available.

The actual problem involves a bit more complicated structure (CompleX cross section, sharp edges on the rope, and Damping) . I simplified it to a pulley-rope simulation just to get me pointed in the direction or a module that will work for me.

Is there a way to do the simulation in ansys? to make it easier, The pulley need not roll... just simulate it assuming its a sliding motion.

The one method I currently have in mind is to apply loads at different points under different time intervals but that would culminate in a large data analysis.
Nevertheless, I am looking for an easier way to go about it.
 
I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Calculate minimum RPM to self-balance a CMG on two legs'
Here is a photo of a rough drawing of my apparatus that I have built many times and works. I would like to have a formula to give me the RPM necessary for the gyroscope to balance itself on the two legs (screws). I asked Claude to give me a formula and it gave me the following: Let me calculate the required RPM foreffective stabilization. I'll use the principles of gyroscopicprecession and the moment of inertia. First, let's calculate the keyparameters: 1. Moment of inertia of...
