Abstract

University of Indonesia Electric Bus was first developed using Hino R260 chassis. For further development, especially to fill out local content, it must be carried out engineering of its components. One of which will be discussed in this paper is the spring component. Reverse Engineering method is used to redesign in such a way. Measurement of the existing leaf springs in the chassis is done. The dimensions and number of leaf springs for the front and rear wheels of the chassis are produced. With CAD software and finite element analysis, a static analysis is performed on each of these springs. Front axle leaf spring arrangement consists of 8 spring sheets with dimensions of width 80 mm and thickness of 10 mm with stratified length. Rear axle leaf spring arrangement consists of 5 spring springs with dimensions of 90 mm width and 12 mm thickness with evenly distributed length. The theoretical stress on the front leaf springs is 512.74 MPa and finite element analysis is 531.5 MPa. The theoretical stress behind the leaf spring which occurs is 721.67 MPa and elemental analysis up to 728.4 MPa. The material for both of these springs is chosen is 65 si7 or SUP9.
