Hi Mustaine3,
I now tried using shell elements and get natural frequency equal to 2 Hz (First mode. The two software (Abaqus and Pro mechanica) gives the nearly same natural frequency.
But the mode shapes look very different. I do not see torsional mode till higher modes in Abaqus. But in Pro...
Hi Mustaine3,
Thanks for replying.
The spool (cylinder) is split in to two halves, the top half being 9 mm and bottom half being 29 mm.
29mm is a bit thicker, so i used continuum shell elements with composite layup initially. Later i tried with solid elements, assigning solid homogenous section...
Hi All,
I am trying to calculate natural frequency of a rotor. I have already run one analysis in pro mechanica which gives me first natural frequency to be equal to 2 Hz.
I am now running the same rotor model in abaqus for comparison and I am getting 1.5 Hz. I suspect it is something to do...
Hi All,
Thanks a lot for finding time and replying back :)
My apologies to be replying late as I am parallely working on another project and still exploring CAE features.
OrlandoTaddeo87: I have now modeled bolt,nut and also the washers in the same part. Then used general contact as you...
Hi,
I am quite new to Abaqus CAE and I am doing bolt analysis for the first time. I want to calculate bolt preload. I have a solid model with two flanges, bolt, washers and nut as seen in Figure 1.
I used contact surface to surface between the washer and flange, bolt and washer, between the...
