    Hi there!

    I am writing this thred becouse of that I saw many different motion simulators. With different motor positions on the frame. So where is the best place to mount them? Especially for 2DOF simulator? (In my case is wheelchair motors)

    Thank you!

    It depends on your design criteria.

    Basically you can have a shoulder mount, compact with front or rear placement, knee mount and foot mount.

    Have a play with each design with SimCalc to understand the basics of design Vs physics, and some of the design influenced geometry outputs: https://www.xsimulator.net/communit...e-linear-speed-and-forces-of-your-design.270/

    There is also the full frame Vs seat shaker aspect: https://www.xsimulator.net/community/faq/full-frame-vs-seat-shaker-designs-which-is-better.213/

    It`s not about design it`s about efficiency :) I want maximum realism. :)
    Thanks for the post. I will have a look.

    En mi caso, uso 2 varillas rosadas desde la parte posterior hasta la parte superior del asiento y la verdad es que funciona bastante bien, no sé si será lo más real que intenta encontrar, no he probado los motores debajo del chasis.

    I place my question here, as it is also regarding motor position:
    By using simtools, I found a good motor positon with good pitch (and roll) efficiency.
    My (maybe wrong) assumption is/was, that the CTC lever and the rod should give a 90 degree angle in rest position.
    In my design this is happening when CTC rest angle is ~ 16 degree.
    But in simtools the pitch efficiency is raised, when I go to 30 degree of rest angle.
    But then the angle between rod and lever is approx. 110 degree, so much about 90 degree.
    So, what's wrong ?

    Any hint is appreciated :)

    Can you please start your own thread and post pictures of your rig and settings to show what you mean.
