Since publishing the RACV Energy Breakthrough handbook which includes Vehicle Specifications, Trial Regulations and Rules, a number of schools have been quick to express concerns about changes to the seat belt mounting rules and the power restrictions placed on pedal/electrically EEVs.
The rule change signals our direction and intention for the future. They are designed to improve rider protection and regulate Pedal / Electric EEVs. As most people are aware, the 2016 event presented many challenges ‘on the track’ and we are keen to ensure that this is not repeated.
We are also working with our Medical and Emergency Services providers to ensure that we taking all the necessary steps to both reduce the risk of injury, through better rider protection and improve the response and care provided following incidents. Ambulance Victoria noted a significant number of back and neck related injuries during the 2016 event.
The essence of the “Technology Challenge” presented through the Energy Breakthrough is to “work together to design and construct a vehicle, a machine or innovation in technology” within the specifications. Our assessment processes are designed to assess:
- the vehicle – its compliance with the specifications and whether it is safe in scrutineering and its endurance performance on the track
- the students – their knowledge and understanding of the design and construction of the vehicle and how personal transport impacts on the world we live in.
During scrutineering, every effort is made to ensure that the vehicle complies with the specifications. The degree of compliance of the vehicle is part of the overall assessment. Vehicles that are considered safe, but not 100% compliant, are often allowed to compete. This is a judgment we, the organisers make. Safety is the overriding consideration.
As in previous year’s vehicles that do not comply with the rules will be closely inspected by RACV vehicle engineers and will only be allowed to compete if scrutineers consider the vehicle safe for competition and that they do not pose a danger to the rider or other participants.
Rule 4.6 Seat belts / 4.6.2 Mounting
This rule is to improve rider protection. There have been too many instances where seats and the fitting of seat belts have not been to a standard that we consider acceptable.
The direction of this rule change complies with the best practice employed in motor sport competition, that is, “the seat belt must be mounted to a major, non-moving, structural member of the vehicle”.
The reasons for this are:
- The seat belt mounting plate, mounting bolt and frame member are specified and are therefore known structural components.
- The strength of a seat is unknown and there is no engineering or load rating of the seat belt securing or attaching points, or the seat mounts.
- The weight of a rider, even in a low speed impact will place a significant load on all seat and belt mounting points
In addition, 4.6.2 Mounting should read as follows:
The seat belt must be mounted to a major, non-moving, structural member of the vehicle.
Seat belts are not permitted to be mounted to the seat under any circumstances.
Upper belts mounted behind the rider’s shoulders are required to be horizontal or no more than 40 degrees from horizontal and mounted no more than 200mm apart so as not to allow the belt webbing to fall from the shoulders when riding.
5.6 Power limitations for Pedal Electric EEV’s or Hybrid One;
It was obvious during the 2016 event that some Pedal Electric EEVs were capable of notably high speeds. The difference in speeds between the ‘fastest’ and the ‘slowest’ vehicle is significant and is not sustainable.
It was clear that a combination of high voltage and a liberal restrictor or cut-out of 30-AMPS, enabled speeds that are risky to other competitors, surpass the safety level of the track and barriers and is contrary to the spirit and intent of the event as an energy challenge.
These rule changes have been informed by two key issues:
- There is a legal limit in Victoria requiring a license to ride any electric vehicle on the road that exceeds 250 Watts.
Based on this limit we have specified a circuit breaker for each of the commonly used voltages.
- 48 Volts is close to the industry standard that requires an electrical license to work on. Therefore 48 Volts has been removed as an option for teams. We acknowledge the lack of forewarning of this change and therefore for this year will liaise with teams to determine an appropriate circuit breaker that can be used to achieve our stated goal.
As in previous year’s we will work with teams over the next two years to introduce these changes in a way that does not increase costs and workloads significantly but works towards achieving our goals of “improved rider protection” and “reduced speed”. In adopting this approach to implementation we will not comprise safety, therefore as has been our practice in previous years, if we consider a vehicle proposes a safety risk to the team and, or other teams and participants we will not allow such a vehicle to compete.
