Ergo Jig Documentation

We'll implement the ergo jig for the 2024-26 season to simulate the cockpit area. In the ergo jig, we will finalize the bounding box based on measurements taken from a jig that is difficult to simulate in CAD:

• Movement within occupants' cell

• Roll Cage height

• Helmet in occupant cell

• Location of ergonomics components for a better experience

• Minor simulation of egress

By the end of this project, our goal is to:

• Find max forearm-forearm width

• Find the angle and position of the steering wheel

• Find the optimal position of seat

• Measure out Pedal box longitudinal range

• Find max torso space

• Find max leg space

• Finalize the bounding box for the driver (Required for Frame to finalize roll cage height Nov 9, 2024 )

The specifics and considerations for designing can be seen from this document:

Ergo Jig with Driver Bounding Box

Specifics of each component

Pedal Jig

Open

Manufacturing Method: Wooden Panel that is held up by L-brackets that are mounted to t-slotted frame

Data Collection Method: Panel will be pushed forward or back depending on size of driver to find adjustability of leg pedal box

Seat

Manufacturing Method: Wooden Panels with bottom of the seat constrained with toe clamps

Data Collection: Seat will be adjusted based on frame that slides up or down

Steering Wheel

Manufacturing Method: Steering Wheel lasercut; mounted with 3D printed jig that attaches to the end of the frame.

Data Collection: Angle adjustable by tightening screws at L-brackets
