Best Practices
Best Practices are not rules, but are suggestions to help teams with design and engineering.
Use of Bicycle Forks
Several teams have attempted to use bicycle forks for their suspension. Bicycle components are designed for stresses along the vertical axis, in line with the fork. However, solar cars must deal with both vertical stresses and horizontal stresses, as the solar car does not tilt as a bicycle does. Additionally, teams must consider how these bicycle forks are mounted, as improper structure will cause the suspension to collapse when turning. Teams must consider how to properly mount the bicycle forks and the impact of solar car stresses on those forks if they plan to use bicycle forks in their solar car design.
Use of Bicycle Wheels
Several teams have used bicycle wheels. As with bicycle forks, bicycle wheels are designed for stresses along the vertical axis, in line with the wheel hub. The solar car's horizontal stresses, along with increased weight of a solar car compared to a bicycle/rider, have caused bicycle wheel spokes to detach during turns and puncture the tire. Other bicycle wheels have collapsed or have bent in half due to the stresses on the wheel. Teams should consider reinforcing spoke attachments and whether bicycle wheels can endure the weight and horizontal stresses of a solar car before incorporating them in their solar car design.
Solid-State Relays
While solid state relays are allowed to be used as the motor or array relay/contactor, some solid state relays could fail closed (a short circuit) rather than fail open (disconnected circuit). Repeated operation of a solid state relay could potentially cause the contactor circuitry to weld closed. Teams considering solid state relays for their relay/contactor should perform adequate testing to ensure proper operation of their solid state relay and incorporate some type of backup in case the relay fails closed.
Crush Zone Materials
Most teams design their crush zone using metal bars/tubes. However, teams should also consider use of foam or other materials for their crush zone to provide impact protection. A full metal frame, especially if built with the same material as the safety cell, may not provide as much impact protection as other materials that are intended to yield/deform upon impact. Please see revised Rule 5.2.3 for new construction guidelines.
