Motion Simulation - Cross Mechanism

Hello, i am new to this forum , i am currently a student and have some question regarding motion simulation.

My project is to do a simulation of a scissor cross mechanism. 

 

During Simulation, i realise i am unable to join the 2 rods proportionally.

Help is appreciated Smiley Very Happy

Hi lalaboix,

 

are you using the LMS Amesim student edition?

 

in the Amesim documentation you can directly find an example of a scissor mechanism. You will find it in the documentation under Demo --> Libraries --> Planar mechanical --> Scissor lift.

You can open and use it.

Hi,

 

I believe the mechanism requires a screw joint.

Within the Motion training, there is an activity on 'scissors_jack'. See attached picture
