Perancangan Kerangka Belakang Mobil Minimalis Roda Tiga

Abstract

Minimalist car three-wheeled car is a new innovation made to maximize vehicle use. In
designing a separate three-wheeled minimalist car, it will combine the trike tilting system where when
turning the car body will tilt towards the turn. One of the main components of a car that is very
important is the chassis. Chassis is one of the important parts in a car that must have strong
construction to withstand vehicle loads. The purpose of this research is to find out the minimalist
three-wheeled car chassis design that is expected to become a modern vehicle.In this study using the
development method by using Solidworks software as a software for creating Arm designs. The use of
Solidworks software also aims to perform numerical analysis to determine the strength of the chassis
by looking at the results of von mises stress on the results of software analysis. In numerical analysis
the chassis uses three tests with different load variations, namely, the load is evenly distributed on the
surface, the load is centered on the center of gravity, and the load when the collision occurs.From the
existing design, the concept of the three of the three concepts was chosen because it was able to
withstand the load even with profiles and dimensions with a maximum load of 8773,735. In the design
of Swing Arm using ASTM A36 pipe material with yield strenght of 250 N / mm2. In the validation of
the swing arm strength using the safety factor of 4. So the validation uses a permit voltage of 62.5 N /
mm2. From the validation between the analysis carried out by the chassis, it was declared safe
because the voltage that occurred in the chassis did not exceed the allowable voltage.
