Electrathon Vehicle: Front Suspension

Description:

The problem to be addressed is that Central Washington University does not currently have a field-able Electrathon America electric vehicle with adequate front suspension. The aim is to provide the vehicle with handling that supports sound ground contact throughout the competition.

Motivation:

This project was motivated by a need for devices that provide ground contact and stability of an Electrathon America electric vehicle. Two separate cars exist, but neither of them are in good running condition. The first one is a cycle-car configuration with a carbon fiber body. This car has a battery housing, electric motor, seat, some steering components, and suspension. The second one is a tricycle configuration. This car is complete, but not in fielding condition.

 

Function Statement:

To design, build, and field a car for the 2018/2019 Electrathon America electric vehicle design competition, specifically suspension. The suspension will provide the vehicle with complete stability and ground contact throughout the competition.

 

Requirements:

The design and racing requirements are stated in the Electrathon America Handbook 2018/2019. The completed vehicle will adhere to these rules and regulation, as well as participate in a race. In addition to these are the following requirements:

Suspension components weigh less than 20 lbs.

Maximum 3” of suspension travel

Must support the overall vehicle weight of 350 lbs.

 

Success Criteria:

Success will consist of fielding the vehicle in an Electrathon America event, and not having any part of the suspension fail to maintain adequate ground contact. Additionally, the handling characteristics of the vehicle will positively impact the driving.

Scope of this effort:

Will only include the front suspension of the Electrathon America vehicle and all of the accompanying analyses for dimension and materials. Additionally, the suspension will be tested when built.

 

Benchmark:

The benchmark for this project is the existing, complete vehicle. The aim is to create a vehicle that is better than this one.

 

Success of the Project:

Success depends on the final performance of the suspension components in a competition setting.
