Research

What are the requirements of our product?

Other things to include are: interesting research, images, links, recap of regulations, etc.Car Requirements

Safety Criteria:

  • Adhere to all the safety specifications as listed by ASC

  • Accommodate a five point safety harness

  • integration of head, shoulder and side containment features into the seat

    • prevent lateral movement of the body

    • must ensure this does not interfere with egress and peripheral vision of the driver

      • not obstructing as much peripheral vision

  • seat belt pass through should be right at the shoulder heightof the driver

Line of Sight

  • height adjust seems it will be risky

  • Sliding seat (lateral movement)

  • Tilting seat

    • might be risky like height adjustable one

    • seems more viable

Comfort

  • support the human body and spine

  • also conduct preliminary research into padding

    • Sheila will look into more of this

    • though you should still research to understand which materials will fit into the final design

  • research into how seats are kept ventilated

Ideas i had/ things i thought about

  • Depending on how we decide to hold things in place (ex glue) will have to test out if it is strong enough

  • Testing the seatbelts to make sure they are functional

  • Testing the materials chosen for the seat if it is comfortable, breathable etc

  • Testing the vision requirements, must be able to see 700m from the ground when the chair is in standard position, certain angles etc

  • Test and validate for ballast bag to make sure it doesn’t go flying (make sure it’s properly secured)

  • Broken down into 2 Analysis - crash and safety and durability (what car companies use)

  • Sled test is performed to test the the sled test performance include: strength of the seat anchorage and the adjustment, as well as the locking and displacement systems

  • Height and weight for different ages https://www.engineeringtoolbox.com/body-weight-versus-height-d_1551.html

How other cars are tested

Crash and Safety :

  • Seat Back Strength

  • Seat Anchorage Dynamic Strength test

  • Seat Structural Dynamic Test forward

  • Strength of Seat Back Anchorage

  • Luggage Retention / Partitioning Test 

  • Head Restraint Energy Dissipation Test 

  • Head Restraint Performance & Strength Test

  • Seat-back Load Floor Test for Retention

Durability

  • Head Restraint Lateral & Longitudinal Stability

  • Vertical Load Strength of Cushion Frame 

  • Seat Ornamentation & Knob Pull-off Strength 

  • Actuator Strength in the Direction of Operation

  • Seat-back Map Pocket Static Strength Requirements

  • Seat-back Torsion Strength

  • Jounce Test (Cushion & Back)

  • Armrest Strength & Operating Effort

  • Latch Catch Spring Test

  • Jump Seat Strength

  • Fatigue Resistance (seat structural fatigue durability test)

  • Vibration Test for Resonance Point Detection

  • Thermal Cycle Ageing Test or Creep Test 

Risk/Unknowns Identification

...

Prompts for areas of investigation include regulation risks (i.e. headlight brightness doesn’t meet regs), mechanical risks (i.e headlight melting from hight high temperature), manufacturing/assembly risks (i.e how does headlight mount to aero body?)
