Connector Separation Machine

This machine was designed to measure the force an electrical connector exerts on a missile as it disconnects upon launch. This was for an acceptance test for an electrical cable (100% testing required). The machine simulates a missile launch by storing enough energy in a rotating flywheel, so that the disconnect event occurs at specified velocity, plus or minus .1 fps. A large electric clutch transfers power from the flywheel, through a pulley and lanyard, to a carriage which holds one side of the connector. The other side is attached to a strain gage. Data aquisition and reduction is provided via a PC with special cards and software. Operator sets speed of flywheel by setting the speed on a DC gearmotor (readout is provided in feet per second), then pushes a button to engage the clutch.
