    Hello

    I am Farhad, and i am new to this forum. i am a mechanical engineering student and i am working on some simulators. the one that i am working on it now is a 4 DOF with linear actuators. I've chosen "Koevermans' flight simulator" kinematics chain (first picture). i couldn't derive it's equations or find any paper related to it. i would appreciate it if anyone helps me with that :)
    the kinematics chain is : 2UPU-2RPU
    one revolute joint in the u joint in "2RPU" is shared between two actuators so it would make a mechanical constraint that decreases the DOF to 4 ! (the kinematics chain is also showed in the second picture) koevermans.PNG kinematics chain.jpg
