Abstract
Because of the complexity of the structure and numerous members, the technology of the full-monocoque coach manufacture has not been sufficiently developed in our country. To expedite the research and development of the full-monocoque, a dynamic stress testing for the full-monocoque coach is carried out under different road conditions. The dynamic stress data in the left side wall of the coach is collected. The method of loading spectrum measurement of the full-monocoque frame is studied, and the stress frequency of the measured data is analyzed. The loading spectrum data for different road conditions is obtained. The dynamic stress level and its variation of the left-side wall of the full-monocoque frame under the conditions of bending, torsion, tension and compression are studied. This study may provide a technical base for the full-monocoque coach's design, simulation and testing.关键词
