bus and large vehicle energy usage breakdowns and source data
bus and large vehicle energy usage breakdowns and source data
(OP)
I'm currently looking at research and available research on bus energy consumption via wheel and acceleration and aerodynamic resistance, and mitigating solutions to each, as well as power coinsumption relatioinship to bus size and weight as well as duty cycle characteristics. Research also will cover oiptions for lighter materials in windows and also in body and interior componentry, such as use of composites, and available research and suppliers.
If anybody can direct mne to any good data or general info it may be of great help, and is much appreciated

RE: bus and large vehicle energy usage breakdowns and source data
A lot of the information you are seeking was done for braking and retardation standard writing but it is still the same information. Braking energy and driving energy are the same thing just applied in a different direction.

There are some SAE papers that have more information but you will have to purchase them. Determining torque at the wheels as required during the drive cycle is much more difficult as there is no published data I've found. Rolling resistance and aerodynamic information is also nonexistent.
