      Remote usage of Aalto's workstations

      Check the page and possibilities, if you find it interesting:

      More info:  -> Etätyö - VPN ja VDI  (FI)  -> Remote Work  (ENG)

      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

        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 ....

      - In classroom (in K1 building, Otakaari 4,
      - In TEAMS, also as recordings (TEAMS, under General -> Files -> Recordings)

      TEAMS link for lectures

      TEAMS link for simulation sessions

      Research Groups:
      - Use Research group selection, check your Group.

      Lecture materials available 
      - more material added 19.9.2023

      • We will use (also) Mathcad for the Group calculation assignments, but you can’t download it from Aalto’s pages.
      • You can also use Mathcad in Aalto’s classrooms.
      • At the moment, there might not be potential issues with Mathcad versions. (in classroom the version should be 9)
      • You can also use Aalto’s classroom licenses remotely …. with some magic, which I can inform you later.
      • You can also download free and limited version … very likely from …

      Schedule 2023

      We will also attend Teknologiamessut on 8.11.2023. The start will be "in the morning".
      Check the programme below!

      Simscape Simulation assignment 1 materials.

      Individual assignment

      Deadline 14.11.2023

      - Instructions for model building available (Word) -> updated (25.10.2023) -> updated later on 25.10.2023 (pages 43 and 44).

          - Set: Different for each flow path to see all the necessary parameters.

      - Excel (updated) for reporting the test values of Phases 2 and 5

      - Report template (PowerPoint) -> fill in version 25.10.2023 -> updated later on 25.10.2023 (3 missing pages added)

      - Controller Benchmarking tool (LS_Control_Test_Bench, added 25.10.2023)

      - Two Simulink versions: 2023b (new Simulink) and 2022b (older Simulink version)

      - LS controllers in action file -> for understanding Simscape realization of LS and pressure limiting controllers (to be added)


      - Matlab - Simulink - Simscape Fluids (Isothermal Liquid)


      Potential Phase 2 issue:

      Fluid Dynamic Compressibility setting in module Double-Acting Actuator (IL)

      - In the first tests without load (mass), the Fluid Dynamic Compressibility should be disabled

      - However, if you add mass (inertia) to actuator as follows (figure below) you can enable Fluid Dynamic Compressibility.

      - the mass will make the cylinder system into a spring-mass system and if you check Velocity plot (Scope), you can notice heavy oscilations during the transient phase (the 1st second)

      - If you increase the mass (10 - 100 - 1000 - 1500 kg), the oscillation amplitudes will  change.
