Is there any difference between constraint element and rigid element? Where constraint element should be used and where rigid element should be used? Do results vary depending on the usage of these elements?
At resonance frequency, the component will vibrate larger than the source vibration. Is this a valid statement?How this phenomenon occurs?Is there any theory behind this?
Is it necessary to annotate specific flatness area (say 20mm dia) around a mounting hole(say 8mm dia) of a support bracket,even if the plane(where hole is located ) is already flat?
Is it possible to consider the force due to belt tension in modal analysis??. I am supposed to simulate for modal analysis of a bracket that supports a pulley .A belt in an inclined direction is running over a pulley with specific tension.
I am supposed to create a drawing with large assemblies. Even if i am using light weight representation, it is taking very large time to create the drawing view and badly ending with memory insufficient error.
I observed that it is taking too much time in the step"Rendering invisible lines" ...
While understanding , a strain vs Frequency graph , i observed that strain is represents as uE . Strain is an unitless property.Then what does this uE represent?
What is the purpose of engine build manual? Whether it is used in engine assembly section or ll be provided to vehicle owner?
What will be its main content?
I have an vague idea that vacuum is used for effective braking system . Is there any online source available to understand about the circuit of automotive engine vacuum pump circuit and its uses .
Else could you elaborate about this circuit?
What is the maximum vibration level that can be accepted in a car engine and the components mounted around the engine. If the maximum level varies depending on the number of cylinders, is there any formula for determining the target natural frequency value ?
Usually i used to work with normal modes(real modes) . I observed there are few other modes in solution form called attachment modes , constrain modes, rigid body modes etc. What are they? Where we can apply them?
Hello all
Is there any possibility\methodology to evaluate the strength of a weld using FEA softwares. Brief overview of the problem: A structure consists of sheet metal parts is failed when subjected to vibration test . The failure is observed because of welding. So is there possibility to...
Hello all
I am familiar in doing FEA in I-deas SDRC. Now need to do FEA in NX 7.5 and i started with an overview.
Here i have some doubts to clarify .. I am starting with few questions. Let me ask some other questions along the thread.
1.When i try to create a new FE model , (.fem file) , the...
Hello
I observed some drawings having the symbol " ~ " without quotes , size is little larger , at the top left corner of the drawing sheet.
What does it denotes?
Hello all
I straight away explain my case. I need to perform eigen value analysis for a heat insulator sheet , which is a two layered metal sheet (same material-) . These two layers are combined with use of 4 spot welds at the corners. Now i made a thin shell FE model with 2 layers and made...
