Project Scope and Objectives:

Create a suspension system for the Spartan Superway that will isolate the cabin from vibration and keep the cabin in a comfortable orientation while traveling down the railway.

  1. The suspension system must keep the cabin level as it traverses through up to 17 degrees of tilt.
  2. The suspension system must reduce the transmitted vibrations from possible variations in the railway.
  3. The suspension system must be able to support the estimated mass of the intermediate scale cabin.
  4. As the pod arrives at a station, the suspension system must level the floor of the cabin with the floor of the platform to provide utmost accessibility.

Project Results:

  1. Successfully designed, modeled, simulated, and fabricated a tension-to-compression suspension system.
  2. Prototyped controls code implementing an IMU and a PID control algorithm.

  • Vicente Viqueira

Project Scope and Objectives:

Design propulsion to allow intermediate-scale bogie to traverse the sloped, suspended guideway.

  1. Choose and obtain a hub motor that will propel the 350lb (approx.) bogie and cabin up a slope of 17º.
  2. Design a mount to secure the motor to the bogie.
  3. Design a spring mechanism to press the hub motor into the ceiling of the track with enough force to produce sufficient friction to move the bogie up the slope.
  4. Interface the motor with a microcontroller to control it.

Project Results:

  1. Found power requirements to be approximately 0.5HP and required propulsion force to be 470N (47.8 N-m at 4in radius) to move the vehicle up the slope at 2mph.
  2. Successfully obtained a motor and controller that fulfilled our power and torque requirements.
  3. Modified the H-bar of the original bogie design to accommodate the size of the motor wheel and mount.
  4. Programmed the Arduino microcontroller to operate propulsion, steering, and braking.
