    Thank you for the participation and Happy Holidays!

    COURSE GRADING COMPLETED

    ... and the information should be in SISU now.

    Assignment grading is done:

    1. Assignment 2: DDH system assignment

    Small hassle on page 10 caused by the Teacher:

    Vi_B= 3.12e-6 which should be Vi_A= 3.12e-6, of course and usage of ideal Vi_B on page 10.

    On page 11 and 12 "non-ideal" displacements. No penalty, if you have used value Vi_B= 3.12e-6 m^3. Same sized pumps would cause massive pressures in the system -> use smaller pump related to B chamber.


    Well done!

    Deadline has been extended -> Friday 9.12.2022. 

    - voluntary assignment

    - extra points (max. 10 p)

    - instruction file available

    The Assignment 2: DDH system assignment report template available

    - deadline: 2.12.2022

    - Classroom is U351 (2.12.2022)

    Three (3) updates:

    1. Classroom U351 on 18.11.2022. New map below!

    2. Course students can attend Fluid Power Laboratory visit on Tuesday 22.11.2022 at 16.15 - about 18.00 o'clock (if they want). This is "just for fun" and to meet Systems course people, and our researchers. Coffee served, also!

    3. DDH pump model (updates):

    The Constant torque model was modeled ... not perfectly (correctly) during the session on 11.11.2022. Change the Product module as follows (related to Vref). New instruction document (version 3) available!

    Keep the parameter name V_i.

    Attention!

    We will continue on Friday 11.11.2022 at 11.15 o'clock

    -  room Y344 (Note: this is NOT the same room as U344) in Undergraduate Centre, (Check the MAP link below) ->

    Audiovisual problems in room Y344 solved!

    ASSIGNMENTS
    The next Milestone Check is on 28.10.2022 .... Seal Friction model.
    The final model should be ready on 4.11.2022.

    Seal model benchmarking (<- click)
    - 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
          - mailbox to return your document will be under Assignments on the left or under Seal model benchmarking (available 13.10.2022), deadline 28.10.2022

    Software:
    In our Fluid Power courses we will use …
    • Matlab
    • Simulink
    • download also Simscape Fluids and Multibody

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