Kelayakan Pegas Daun Dalam Penerimaan Beban Optimal

Abstract

Until now days a lot of vehicle still used suspension Leaf spring either in front or in rear
suspension. Commonly the this suspension consist of several peace of springs that called leaf
spring. This research is focus on laboratory work without experimental test. As a result only
theoretical conclusion. Natural frequency by modal analysis show that all mode are more than
100 Hz. It is very dangerous value of safety passengers and the suspension its self. But with
harmonic simulation between 1 until 10 Hz input frequency will be resulted no more than 20
mm amplitude. This is the range where passenger still get comfortability according to Jane
way diagram of comfort ability. Consequently a lot of people or automotive engineer still use
this kind of suspension .
