Northeastern Electric Racing

I am currently the lead suspension engineer for the Electric Racing Team. In this role I manage:

  • simulation

  • mechanical design

  • manufacturing

Simulation

I am responsible for building up the team's first custom simulation software to model full car behavior in a dynamic solver. I did this over the course of about 5 months in the summer through lots of research on what other teams were doing and what was available in Matlab.

​

This simulation software is based in Matlab using Simulink and Simscape add-ons.

I built the software to include data visualization for parameters such as spring travel, camber, rake, ride height, and more. This helps us diagnose problems with proposed suspension geometries in a dynamic environment instead of making static approximations.

We can also create full car testing rigs that would normally cost lots of money to test the car at. One of the rigs is called the four post rig that can excite all four wheels individually to measure the response of the car under situations such as rolling, braking, etc. This is very insightful into what spring and damping rates we should run and if our suspension solution is maximizing the grip in the tire.

Mechanical Design

I am responsible for the design of key components such as the rocker and mounting to the chassis. A DFM thought process was used on these components as we do our manufacturing in house. This led to the mounting being designed to be water jet and then welded to reduce manufacturing time as well as reducing as many operations as possible on CNC components like the rockers.
