hi, I am here to (as already written in the presentations section) try to fill some mechanical gaps that I can only have, being I of the information industry.
I am carrying out the magisterial thesis and I need to model a vehicular barrier, like those found at the entrance and exit of the highway, or multi-storey parking spaces.
I quickly describe the project: thanks to the collaboration of a company in the area, we are putting on a project related to an automated parking.
at the entrance of the access gates, I have some vehicular barriers that I have been able to inspect inside. the main components that handle the auction are two:
1. engine
2. spring
initial phasea closed barrier (in fact, to understand us) acts the spring which is initially compressed. motor-motor coupling acts as a 'fresh' to the opening movement.
this initial phase ends when the spring is in rest position, i.e. when the barrier reaches 45° (compared to the horizontal position).
central phasestarting from 45°, the spring begins to resist the opening movement, since it begins to stretch over the rest position.
This is where the engine begins to act actively at the movement: spring expansion is due to the engine-reducer coupling couple. in this way the barrier is brought to reach about 90°.
final phaseFinally, the engine slows down its movement in order not to make brusque movements, action that actually brings the barrier in perpendicular position to the ground. this happens because of the integral action of the pid place to control the movement in order to avoid overshooting.
I'm building a simulink model to simulate the auction dynamics, and I need a hand to understand how to intervene.
I followed control of mechanical systems at the department of mechanical ing of my university, and we analyzed the same system, with in only motor, however!
I have no idea how to consider the spring (which acts on a lever). at the meeting with the company told me to see it as a strong couple, but how do I calculate it?
I don't have actual data yet, but in the meantime I attach a pdf with the system
Thank you in advance!
