    Final Grading done!

    The DDH system assignment has been graded. Very nice!

    Have a nice holiday and thank you for the course!

    .... old material below .....

    The exercises continue on 17.12.2021 at 11.15 o'clock in TEAMS.

    New deadline of the assignment is Monday 20.12.2021

    Still one simulation model to complete -> DDH system assignment-> assignment materials available

     - Check the Powerpoint (version 03122021) for the DDH model.

    - Report template available (02122021)

    - Pump model benchmarking tool (Simulink) available -> build your pump model by using it

    - pump benchmarking plots Powerpoint (3.12.2021) -> compare your own pump performance with example plots (efficiencies with different loss sub-systems)

    Latest File name: Exercise DDH system v 03122021.pptx

    Topics of the last exercises: finalizing the model and filling the report. Help available!

    ..... old material ...

    Assignment Valve model benchmarking, (deadline 15.10.2021) has been graded. Link HERE.

    Those, who are late with this -> please upload your document. The mmailbox should be open. See slide set 4 HERE for instructions, pages 21-23 (under Materials).

    Silde sets 5 and 6, also added HERE (under Materials).

    Videos should be available in TEAMS classroom, check this page (below).

    Next steps ...

    - seal forces etc. -> seal model Benchmarking deadline is 5.11.2021, but we can try to make the documentation on Friday

    - model finalizing

    - cylinder's end forces and valve spool dynamics (check if you have Model linearizer available for Bode plots)

    - can you install it? Is it under Control Systems Toolbox?

    1st assignment: Cylinder Model Benchmarking GRADED, (deadline was Friday 1.10.2021), link HERE (under Assignments)

    Next assignment is Valve model benchmarking, deadline 15.10.2021. Link HERE. See slide set 4 HERE for instructions, pages 21-23 (under Materials).

    Instructions

    - in video sessions

    - and in slides sets.

    Please, check Video files of Friday sessions in TEAMS classroom of this course, click HEAR for the link

    Next session (8.10.2021 at 11.15 o'clock) in TEAMS only (link below)!

    Join Microsoft Teams Meeting

    Course materials added HERE (under Materials).

    update 16.9.2021 at 23.14 o'clock):

    Here is the TEAMS link for the Friday sessions:

    Join Microsoft Teams Meeting

    IMPORTANT!

    The teaching takes place only in TEAMS -> if you are studying "remotely" -> download and install Matlab/Simulink (instructions below),

    So, NO classroom teaching so far! Sorry about this inconvenience!

    Update (17.9.2021):
    Course materials added HERE (under Materials).

    Usage of Matlab:

    1. You can download Matlab AND Simulink, install it and use you own computer. Instructions for downloading below.
    2. You can use remotely Aalto's IT classroom computers. Links to instructions below.

    We still try to ...

    1. visit the laboratory

    2. have a "group discussion" (probably in TEAMS)

    We will build up fluid power simulation models "from the scratch" and analyze their operation.

    In our Fluid Power courses we will use …

    • Matlab
    • Simulink
    • (you can also install Simscape Fluids, but it is used only in Systems course)

    Dowload and install Matlab and Simulink

    As you have Aalto's IT license, you can download Matlab and some other useful software to your personal computers, if you like from Aalto's web page .... https://download.aalto.fi/index-en.html

    Remote usage of Aalto's IT classroom workstations
