Hi all, 

I 'm doing OS-T 1380 tutorial about Equivalent Radiated Power but I don't understand what is dynamic radiation. 

Can anyone explain for me?

Thanks so much.

    Hi Nancy, 

    You can refer to help of ERP. 

    This radiated power is the source of noise response,  and ERP analysis is a simplified method to get the maximum of dynamic radiation of a panel in frequency response analysis. 

    From the formular we can see that it doesn't predict the noise response(check Acoustic Analysis online help) directly, but it calculates the radiated power from the radiating surfaces, for example an e-motor housing.

    I am sure you will have a better understanding by doing more tutorials of both acoustic analysis(OS-T: 1395, OS-E: 0335 etc.) and ERP analysis. 

    Hope the above is helpful. 

     

    Thanks.
