Hello Everyone. I need some advice in calculating the pressure of a roller printing machine. The machine is operated by a geared rotating lever which moves the impression roller across a print surface. I had thought it was a case of using the equation for rolling friction to work out the normal...
It is to be a ram that would impact an object with different speeds and forces. The piston would come out and impact at a specified force.
Would increasing the torque, which would generate a greater force, drastically reduce the stroke speed?
Thanks for the reply. The problem is that the current system seems to cheat a little by using the pneumatics. The output force can be increased by increasing the pressure and the frequency of the actuator movement is dictated by a solenoid valve allowing air into either side of the cylinder...
I am investigating linear actuator technologies as an alternate to using pneumatics. I require independent control over both the output force and stroke velocity. The force needs to be varied between 30-160N and the stroke velocity varied up to a maximum 1.2m/s. The maximum frequency of actuator...
