thanks guys. unfortuantely, my deadline is on 1st june so dont really have time to implement everything - i guess a rough estimate from the unfiltered data will suffice...
Hi
I need a value for the 2d lift curve slope of the NACA0012. The Mach numbers I am concerned with are less than 0.1 and hence a incompressible value would suffice. The Re range is from 0 to around 275,000. Any ideas on how I can get this? Will XFOIL do it??
I have tried the Abbot and von...
Hi
I am measuring the bending strain via strain gauges for flutter tests but need a method to filter the data. As the gauges are sensitive the data file contains a lot of 'noise' (its not noise technically, the voltage just jumps up and down by small amounts). How can I filter this data to get...
thanks for the tips but unfortunately i have very little time and equipment to play around with.
using a camera is also another way i was going to use to get the tip deflections at the trailing and leading edges (and hence twist). basically i plan to take a picture of the wing tip (end on, so...
Hi
I am trying to calibrate strain gauges using two beams, one of which has bend-twist coupling. I have two full wheatstone bridges; one for bending and one for torsion. The dimensions are 3x95x900mm. The strain gauges are placed near the root and I want to correlate the voltage with the...
Hi
for an experiment i need to measure the twist of the wing (a plate with a foam covering) at the tip using strain gagues (i have 2 full wheatstone bridges; one to measure bending and one to measure torioanal strain) which are located close to the root. i have calibrated these using known...
Hi
I need to modify the direction of the unit normal of a 2D mesh. The part is in the yz plane and I want the unit normal to point in the positive x direction.
How can i modify the mesh? Thank you.
(In case, you're wondering why i need to do this, i use the node coordinates from abaqus and...
I have tried the assembly option but the coordinates are relative to the local system and therefore they will also be in xy-plane.
not sure how to get the actual coordinates from abaqus? do you know how to corus?
(i need to output the input file as a nastran file - not sure if this restricts...
Hi
I am modelling a rectangular plate as a 3D shell (also using the 'shell' option within the 'Sections' option. I just need to draw the cross section of the plate (dim: 3mm x 95mm) but I want it in the yz-plane. By default Abaqus works in the xy-plane and I can't seem to change it.
Eventually...
