DAY 14 - chassis

Did some improvements on the chassis. Measured out the cockpit dimensions and built a cardboard model of it in my backyard just to see if 2 people would fit in it comfortably. It was perfect. enough room for 2 big people too.

the chassis is made out of square tubing (30mm x 30mm) with a thickness of 1.6mm. The reason i am using square tubing is that its easier to cut, weld and mount stuff onto it. once the design is complete, i mitght replace some sections of square tubing with round tubing in areas where nothing needs to be mounted onto it.

The chassis also has to be triangulated, but this will only be done later on when most of the chassis dimensions are fixed. For triangulation i would use round tubing (20mm diameter and 1.6mm thickness). This is the idea for now, things might change...

Right now the chassis weight is 62kg (solidworks worked it out), the steel tubing has a density of 7850 kg/m^3

62kg is not bad for now, i am looking at 80 - 90kg once everything is completed. However ill try to make it as light as possible.


it has a height of 0.35m (black tube to black tube) and height of the roll bar is 1m from the bottom black tube.










































the wheelbase is approx 2.15 m. About 0.2 m shorter than the westfield XTR2 with a 1300cc hayabusa engine. However the wheel base might increase if i find i need some extra space for the front suspension, pedal box and steering rack. Ill try my best to stick with this.











the seats have to be slightly modified to give space for the roll hoop. i Will chop off the corner sections.
