Project description 2018
Lab schedule 2018: This year the experimental work is done in the form of three demo lab sessions: Thuesday 30/1 kl 9-10, Thuesday kl 13-14, and Wednesday kl 13-14 with booking according to a list sent by e-mail.
Lab data for the frame exposed to an impulse load:
- A document with comments on the data file
- A file with free vibration response for all floors: transdat
Lab data for the frame driven in steady state at resonances:
- A document with comments on the data files.
- Files with data at resonance: res1, res2, res3, res4, res5, res6
Comments on how to write the reports for Project 1 & 2 are given here
Lecture on measurement techniques
Juan Negreiras slides from the guest lecture (2018) are here
A document with an example of FFT according to Juan's lecture with a function performing it is found here.
Project 2 in 2018
Project assignment 2018
Experimental: The laboratory modes & frequencies as well as the transient data from the demo lab 2018 are needed. Transient data: Matlab data files with three columns; the first is sample number, the second is time, and the third is the corresponding data: hammer, acc1, acc2, acc3
Report: Comments on how to write the reports for Project 1 & 2 are given here
