Hello,
Complement to this question when applying the time varying load. How can we import a predefined time-load (one dimension is time value, the other is load value and other is position) to get dynamic transient response?
Many tks.
Tks for reply,
I would rather clarify my question. Actually I want to have the transient time domain response of a mechanical system to a Gaussian white noise input excitation.
Always appreciate for replies,
Hi all,
Do someone know how to simulate the time history response of a structure to a random excitation. Is it true if the Spectrum analysis give only the PSD not the time history?
Many thanks
Hi all,
Do someone with experience on command DELTIM can help me while doing the dynamic transient analysis. I dont understand why the time history list data gives always the sampling time step different to the one introduced in DELTIM command.
Tks very much,
Hi,
I generate a signal from Simulink, then I add a random noise to it by 2 ways:
- Always in Simulink with the block "random number"
- In workspace with the command "randn".
I keep the same SNR and identify the frequencies from the noisy data, but the effect of this noise to the signal is...
