Forces in Junctions

Original project made with Autodesk Inventor 2014 as a Dynamic simulation. The action is due to an imposed motion applied to the (green) crank for 10 seconds. The curve of movement is accelerating from 0 to 30 rot/min (180 deg/s) in the first 2 seconds, and from 30 rot/min to 0 in the last 2 seconds. This project emphasizes the forces implied in a moving mechanism. The assembly contains a crank, two levers, two forks, and support. The compression springs are added to participate with other forces in the system. A graph of forces in two junctions presents the evolution of forces. The two junctions are revolution-type on the forks. As usual, you will find all the .iam and .ipt files so, if you work with Inventor, you can download them to enter Environments / Dynamic simulation and to change anything you want. A simple skill in working with the Dynamic Simulation module in Inventor is recommended. Watch what's happening and... Enjoy!
