DESIGN GOALS

With a limited amount of power, the focus is primarily on the power to weight ratio of the vehicle. The only means to improve this critical parameter is to reduce the overall vehicle weight compromising the overall safety parameters of the vehicle. The objective of the frame design was to support the suspension systems, engine, steering and other systems while meeting the SAE regulations with special considerations given to safety of the occupants, ease of manufacturing, cost, quality, weight, and aesthetics. Moreover, care has been taken to ensure that there are minimum welds on the frame pipes and maximum bends ensuring better strength and less cost of production of the vehicle. 

Design Methodology:

Initial step: –The design was initiated by a sketch. Our sketcher made an imaginary design of the bike with attractive aesthetics.

2) Following the sketch, Designers designed a frame in SOLIDWORKS 2016 considering all the parameters like wheel base, battery, motor, wiring, suspension, fork, dimensions.

3) After the completion of the frame design, we have done analysis on the frame in ANSYS 16.2. Analysis includes front impact test, rear impact test, side impact test and torsional test.

4) Based on the analysis result we have modified the design and finalized it.
