Pseudo-dynamic method for structural analysis of automobile seats
Carneiro, J. O.; Melo, F. J. Q. de; Pereira, J. T.; Teixeira, V.This work describes the application of a pseudo-dynamic (PsD) method to the dynamic analysis of passenger seats for the automotive industry. The project of such components involves a structural test considering the action of dynamic forces arising from a crash scenario. The laboratory certification of these automotive components consists essentially on the inspection of the propagation and extension of plastic ...
The dynamic analysis of piping systems using pseudo-dynamic techniques
Melo, F.J.M.Q. de; Carneiro, J.O.; Lopes, H.; Rodrigues, J.F.D.; Gomes, J.F.S.This paper describes an application of pseudo-dynamic techniques to the dynamic analysis of piping structures. Essentially it consists in coupling a direct time integration algorithm, such as the Newmark method, to an experimental step. At each time step the integration algorithm generates a displacement vector of the structure, which is prescribed for the test specimen. This is mounted in a rigid test rig fitt...
