This study aims to analyse the structural design of a village car chassis that uses a ladder frame type to simulate extreme road conditions in countryside areas. The research method used is finite element analysis. The material used for the simulation is Carbon steel tube JIS G 3472 STAM, STAM 440 G and for the bracket used Carbon Steel AISI 1020 (UNS G10200). The load simulation was varied from the chassis conditions of 0°, 15° uphill, and 15° downhill. The pedestal conditions on the chassis are varied from 4 wheels to 3 wheels. The variation of loads applied to the chassis structure consists of 1) normal loads and 2) extreme loads. Based on the data from the analysis of static loading on the village car chassis, the maximum stress generated was 297 N/mm 2 in the 15° uphill chassis conditions without the support of one right rear wheel. The maximum displacement was 12.2 mm in 15° uphill conditions without the support of one left rear wheel. The average value of von mises stress on the chassis was 156.41 N/mm 2 with an average safety factor value of 2.19 and an average displacement value of 4.36 mm. It can be concluded that the chassis design is safe to withstand dynamic loads according to industry specifications.
