THE MAGNITUDE AND THE RATIO OF THE THREE ESSENTIAL STRESS COMPONENTS IN PSV' FRAMES

The stresses arising in the frame structure of buses during service can be divided into three essential components: stresses from the manufacturing process, stresses from the pay load and stresses coming from the operation. The time history, the statistical behaviour of these components as well as their measuring methods substantially differ from each other. The paper shows the magnitude, the ratio, the range and the extreme values of the above mentioned three components in the case of several psv categories. The results are based on a great number of measurements. The knowledge of these load or stress components gives the basis to the strength and life calculation of bus frames, or to solve the problems of unexpected fractures during the service as well as to simulate, and to reproduce the service loads in laboratory tests.
