On Development of Load Spectrum for Full Scale Fatigue Test of Trucks in Laboratory

To support the development of automotive industry in Indonesia, especially for the truck manufacturing which at present time employ about 80% local components, the laboratory for Strength of materials, components and structures has developed load spectrum used for full scale fatigue test of trucks. The load spectrum which is required for the test represents the road surface conditions of the roost Indonesian streets.

This paper describes measurements method, road types, data modification method and the application of data as load spectrum for laboratory test.
