Further marks will be available for identification of the mode shapes for the first five modes from the blade data provided (please store these as mode shapes_bladel). You should normalise the mode shapes so that displacement at Point 9 on Figure 1(b) is equal to 1. Any damping ratios used in the calculation of these mode shapes should be stored in a vector labelled modal_dr_bladel. You should repeat the analysis for the data you gathered (blade2_data.mat). Your code should then make comparisons between the behaviour of the blade that you tested and the one for which data was provided. This should occur in an automated manner, with the results saved in appropriately labelled variables. You should think about what kind of information an engineer studying the vibration of these blades would find useful to know. Bonus marks are available for additional analysis. This could, for example, be through correctly applying appropriate methods that go beyond those presented in the lectures, e.g. methods you have found in your own independent research. You will also be marked on whether your code runs successfully; on how compact it is; on how easy it is to follow; and on whether your choices for signal processing when transforming from the time to frequency domain were appropriate. Note that you should not make use of modal analysis functions in the MATLAB Signal Processing toolbox (e.g. modalfit) or any functions found online (e.g. from MATLAB Central). You may, however, make use of standard built-in MATLAB functions (e.g. for Fourier transformations, peak picking etc). There will be lots of opportunity to gain help and advice on your code during the online drop-in sessions and the face-to-face surgery session. However, the demonstrators will not be allowed to help with all of the aspects of the assignment - some tasks will need to be attempted on your own. Please see below for how marks will be awarded and which elements you can access help for. However, at any point the demonstrators will be able to give help with the use of MATLAB e.g. "How do I put two plots on the same figure?" but where indicated won't directly show you how to solve the dynamics problem e.g. "How do I plot an FRF?".
