Design, Analysis and Testing of Square Bar Welded and Bent Chasis for Indonesian Rural Transport Vehicles

The chassis design has been done for rural transportation vehicles in Indonesia with welding and bending methods. The result of static analysis using ANSYS software shows that the chassis produced by the welding and bending method has the same performance if seen from bending load and torque. Likewise with the results of construction tests, welded chassis and bent chassis has a linear approaching deformation characteristic, proportional to the force load. However, the characteristic of chassis deformation of bent chassis is only linear up to 3.3 Nm load, then decreases drastically at more than 3.3 Nm of loading. In torsional tests, welded chassis and bent chassis have the same linear deformation characteristics, but the performance of the welded chassis is better than the bent chassis. Overall, ANSYS simulation and Static test results for a 250 Nm load indicates that the welding chassis and bent chassis are both still under the permitted critical conditions or it is secure against the provided loads.
