1. ## random analysis

Hi sir, Can anyone tell me how to convert the PSD (m/s2)2/Hz data in to the Acceleration (m/s2)
2. ## modal analysis

Hi Sir, I performed the modal analysis using optistruct as a solver. Can you please tell me which mode is the natural frequency of the system? How many frequency I needs to extract. If (Freq. range is 10 to 1000). What is rigid body mode? Can I considered this modes to find out the response of the system while doing the FRA
3. ## Dynamic analysis of a Component

Hello, I want to know the procedure for performing the dynamic analysis of a component using the optistruct. The following are the conditions. 1. 50-500 hz frequency 2. 15g acceleration. Can you please let me know know how to perform the analysis. Regards, Rajesh.
4. ## Frequency response analysis

Dear rahul, In the example said by you, uniform structural damping coefficient is calculted but how to calculate this in my component. What value should I keep in WTM_V1?? Regards, Rajesh
5. ## Frequency response analysis

Dear rahul, I just want perform a analysis which is not depend on the time. Simple one cycle analysis using frequency range, amplitude. Regards, Rajesh
6. ## Frequency response analysis

Thanks a lot for the reply. The following are conditions for the analysis Sweep frequency -10-55-10hz Amplitude-5g Using these values how can i perform the frequency response analysis. Can you let me know where can i apply the load. As I said before my component is a headlamp of a car. Regards, Rajesh.
7. ## Frequency response analysis

Hello, I have query regarding frequency response analysis. My component is automobile lamp( eg: Head lamp of a car body) i have meshed the component using tetra mesh. i have performed the modal analysis. Now my query is using these frequency values obtained from the modal analysis i would like to know in detail how to perform Frequency response analysis. Please help me. Regards, Rajesh
