  1. Thank you for the posts! I am sorry that i didnt wrote earlier, had much to do. But i found in a book some possible calculations for the forces of the system (do not know if they are rigth. I wrote a little matlab script to calculate the forces at every possible angle of the crank system. The results show me very high forces at pi and 2*pi of the system. (I think thats because of the singularities. My question is how to solve this problem. The system should not have fast motions, in the contrary it should move slow and transfer forces! Or is it better to avoid this positions and rotate only between 0 and pi? (I would like to use the whole rotation, if it is possible)
  2. That is also my opinion. The problem is, that the rotation speed of the motor will be very low. Thatswhy i need to calculate it, to know which moment i need to move the system.
  3. Thank you for your fast answer and the book! I know this kinematik equations. I do not understand how to calculate if there are problems in dead points, for example the system will stop and not move in these points?
  4. Hello, at the moment i am trying to design a crank slider mechanism. This mechanism should be driven with the help of an e-motor. Through this rotation a slider should move. Unfortunately i have some problems, because i can not find any good books about the calculation of these mechanisms. For example i do not understand how can i calculate the system to avoid it to come to a stand at the dead points? Can someone help? Thank you in advance!
