Using load data from txt file

[OptiEng]

Hello All,

I have Fx, Fy and Fz loads (in newtons) against time (in seconds) and need to load a component using this data. I am used to defining loads the standard way in Abaqus and never applied loads from this form before.

Each cylce is around 1.5s long so would also look to run this for quite a few number of cycles.

If its not too difficult to explain how to do this in Abaqus 6.9-1 could you please help?

Thanks

Create 3 loads and 3 amplitudes set up your step size to match the number of rows of data in the amplitudes. I hope this helps.

Thanks for your input Rob, I am going to need to find some guidance at a more deeper level on this one though, sorry. I am not used to applying loads from data like below:

Time (s) Fx (N) Fy(N) Fz(N)
0.1 10 12 3
0.2 12 15 5

etc...

When you say create 3 loads, you mean in the CAE like applying a force? Also I am not used to applying amplitudes. I will check out the abaqus manuals to see if I can find some more help there too.

Thanks

Create a separate load for each XYZ and create amplitudes with:
For X
.1,10
.2,12
For Y
.1,12
.2,15
For Z
.1,3
.2,5
In each load you can specify the amplitude (it is a drop down in the load definition window.

I hope this helps.

Rob thanks again for your input,

Yes problem is I have over 1000 time points, which would take a long time to input, I will have a go at placing this into the input file.

Thanks again

Copy and paste from excel! I hope you read this in time.
