Mustang Advanced Engineering Project Spotlight for Club Car

Club Car has constructed a new high throughput production line for the assembly of electric and gasoline powered golf cars which called for an EOL tester.  The new production line is a high throughput conveyor driven line with a pull line time cycle of 60 seconds; capable of 60 jobs per hour.  The primary factor to keep in mind is there is 45 seconds to perform the required test with 15 seconds of move-in and move-out time.

It is understood that the vehicle will be securely located on the cart, which is indexed into position.  The lift will be hydraulic operated and raised to contact the tires of the golf cart and lift ~6”.  This lift stroke of 6 inches is estimated to be enough to raise the vehicle above the build cart fixture.

The required tests include verify top speed; monitor; display and save the actual ground speed of the golf cart and make a pass/fail decision based on an information table located on Club Car’s Sequel Server Database (SSDb).  Also, test the pedal Down Regenerative Braking (over drive vehicle speed), test the walk-away Braking System, and full scale, throttle position on electric vehicles.

Club Car has requested two different configurations of the dyne.  The first configuration assumes the golf cart is positioned and the build cart is constructed in such a manner that the dyne can rise straight up to gain access to the cart wheels.  The second configuration assumes the golf cart is positioned and the build cart is constructed in such a manner that the dyne will require both a vertical movement as well as a Horizontal movement to position the roll under the golf carts tires.  This method also requested a minimum distance between the bottom of the golf carts tire and the top of the build cart.

The system will require:

  • ~6” of height for the dyne frame and rollers.
  • +/- 0.25 of dyne height variation to adjustments
  • +/- 0.875” (20 mm) of cart height variation
  • Total gap should be 6+0.5+1.75”=8.25”
