Constrained-layer damping on NX 8.5 ?

 

Hi everyone,

 

I am plan to use NX 8.5 to run FRF on constrained-layer damping plate cases. Do it have the capability to run it? which solution SOL should i use to solve it? Can I use NX nastran - SOL103? 

 

Sorry if keep bothering asking question.

 

Thanks.

Dear Faizal,

For FRF results you need to run SOL103 RESPONSE SIMULATION. Also you need to have a valid license of RESPONSE SIMULATION (RS) module. Create and solve the solution and then create the Response Simulation solution process.

 

Frequency response function (FRF) is a transfer function that lets you evaluate the frequency response of one or several selected output nodes or elements to a unit force load at a selected input node. Transmissibility lets you evaluate the frequency response of one or several output nodes or elements to an enforced motion such as displacement, velocity, or acceleration at a selected input node.

You can evaluate displacement, acceleration, velocity, stress, strain, shell stress resultant, or reaction force.

Results are displayed under the FRF and Transmissibility Results node in the Simulation Navigator. The response functions are stored as function records in an AFU file with the same name as your Response Simulation solution process. In the AFU file, the node or element ID and input and response directions are reflected in each function's name.

 

Best regards,

Blas.
