The design and development of more environmentally friendly electric vehicles to replace
fossil fuel vehicles is a recent focus of many vehicle manufacturers. The use of
lightweight materials in electric car structures, the use of advanced production processes
and special electric vehicle chassis designs will be the key points in increasing energy
efficiency. As with conventional vehicles, electric vehicle chassis designs must be highstrength, cost-effective and lightweight structures. In this study, a design and analysis
optimization study were carried out to transfer the vibration to passengers less against the
forces coming from the road in the electric vehicle chassis. Micro vehicle electric chassis
design was designed with the CATIA V5R20 program, and the sub-modules in the
ANSYS program were analyzed with static structural and modal analysis. In the micro
electric chassis design, ultra-high strength steel material was used and the vibration effects
of this material on the chassis were observed through six different vibration modes. In the
analysis results, after the design optimization, 20.26% reduction in the amount of
deformation and 1.22 times the equivalent stress amount was determined. For the first
resonance reached in Mode 1, the frequency value increased from 89 Hz to 104 Hz, while
in Mode 6, the last mode, the frequency increased from 345.78 Hz to 395.48 Hz. This
frequency value results also show that design optimization with ultra-high strength
material in the electric vehicle chassis has a notable positive effect on vibration and
deformation values
