Mechanical dimensioning stage

As mentioned in the January 21st, 2015 post “Project defined, off we go”, during these four weeks, we worked on the choice of the vehicle to be converted, according to the list of 10 candidates cars published in the wiki. We first aimed to identify what were the necessary technical information to make a mechanical dimensioning of each model in the list using the Excel spreadsheet published to GitHub. At this purpose we built a table that allowed us to properly collect these information for each model of choice. Once we completed the information collection, which required several Internet searches, we moved to the analysis of the collected data stage.

 

Starting from this first phase of data screening, some interesting considerations have emerged:

  • For the same car model, there are different versions, which can differ quite a lot in relation to the technical data that we take into account for the mechanical dimensioning.
  • The differences between different models can be traced back to an average value that represents the ideal subcompact car model, the vehicles category of our interest for the conversion.
  • The tire measures of different car models in the list can be traced back almost all to the same value (185/60 R15).
  • The theoretical collected and calculated values will still be experimentally verified once the prototype building stage starts.

Then we have used the mechanical dimensioning Excel files to process the collected data for each car model. We have determined the reference physical parameters to choose the most suitable powertrain. This study has confirmed what we determined with the previous points. To finalize which powertrain is suitable for the selected car model, we also understood that it’s wiser to work on a mechanical dimensioning that descends from the average values contained in the data collection table and the 185/60 R15 tire size. This is just what we’re working on these days, defining the mechanical dimensioning of the “average subcompact model”, and choosing which powertrain to implement.

We also began to study what’s on offer in terms of powertrain, favoring those companies that manufacture asynchronous three-phase alternate current electric motors, and that offer support to the development of customized technologies.

We are working on an official presentation of the entire iaiaGi project that we will publish within the next days.

Stay tuned.
