COURSE GRADING COMPLETED
... and the information should be in SISU now.
BW,JyrkiOlder updates:No actual new for 1.12.2023. All the material has been provided by 24.11.2023.Check the DDH material available (report template etc.) under ... Assignment 2: DDH system assignment.New deadline for DDH assignment is 5.12.2023.We went through DDH assignment on Friday 24.11.2023 in Undergraduate Centre and in TEAMS (link below).Updated version(s) of the pump benchmarking tool available (24.11.2023).Assignment materials (slide set version 5) now available including report template.The classroom will be the same the next week (U351).Attention! This different from rooms U344 and Y344, of course!Check the rooms below (Schedule).- Fill the FINAL report (available)
- Check DDH file 5 for FINAL instructions
All the material should be available now (23.11.2023).DDH material available under ... Assignment 2: DDH system assignment.New features for the DDH system (on 23.11.2023, DDH slide set 5):- Load holding valve- Pressure oscillations- Testing with ... acceleration feedback- Changing the gravity vector of ... direction of gravity load- These are also content for the FINAL report.................... HISTORICAL MATERIAL ..................The grading is done for ...The recorded session on Friday 27.10.2023 did not include much sound after the first hour.Sorry, we will try to make it better the next time (Friday 3.11.2023 ->).Also, we reworked/repeated the DDH related things on 3.11.2023!- Use the template available (includes also the cylinder tenmplate).
- Instructions in slide set Exercise 4, pages 18 ... 20
This should have been done:Assignment 1 materials available!- 27.10.2023 Seal model benchmarking
- fill in the template document
- benchmark your seal model(s) by using instructions in Exercise 6 slide set, page 21 ->
- benchmark and upload your filled template document
The recorded sessions should be in TEAMS as well.MAP link belowTEAMS link availableCheck for- Textbook (myös suomeksi, valikosta vasemmalta)Software:In our Fluid Power courses we will use …- Matlab
- Simulink
- If you attend Systems and/or Basics course:
- download also Simscape Fluids (Isothermal Liquid toolbox needed) and perhaps Multibody
