Turbine D:
thanks - it is a pure pleasure to read such posts
Good structures must be capable of absorbing vibrations and not amplifying them and there are many techniques that can be incorporated to accomplish this. I used the word "robust". Care must be taken to not reduce weight of structures that could compromise long term structural integrity although this is often looked at during weight reduction/saving campaigns to improve performance.
could you pls tell a little more on techniques to absorb vibrations? The lower the weight and stiffer the shape the higher is the supporting structure natural frequency but doest is solve the vibration problem?
Looks like multiplatform optimization (technical characteristics vs unit costs vs weight vs project time etc)
