Week 8 & 9 - Four Bar Mechanism

WEEK 8-9

This is the general element list of all the components of the session

Use week 8 4 bar mechanism to begin with

Create an extension to 4 bar mechanism to simulate car trunk mechanism , using the given points

Create graphics using point G, H, I and create bodies using it which will be extension of body 1

This is the required mechanism

Where input is going to be based on curve

Import the curve

Define the input for crank using curve which we imported in previous step

Now import the models of car trunk and trunk lid

Their location are already described and no need to reorient them

Disable the already existing bistop torque and driving torque

Connect the trunk lid to 4 bar mechanism as a single body
And connect trunk to ground body

Setup a collision detection function

Run simulation

The red zone indicates the zone that came in physical contact with other group specified in collision detection tool

Yellow zone indicates the zone which is in close proximity with other group specified in collision erection tool

This tool helps in detection of 2 bodies in motion which are about to make a contact with eachother

BITSTOP funtion is used to define the angle mae by the trunk lid by restriction its motion between +10 and -10 degree
