Previous issue date: 1971-01 / El problema principal abordado en este trabajo es la determinacion de la respuesta de una placa plana rugosa rectangular simplemente apoyada, excitada por flujo de capa limite turbulento. Se encontra una solución general de la respuesta de desplazamiento para un sistema contínuo linear cualquiesa, excitado aleatoriamente. El metodo utilizado hace uso del analisis armónico generalizado y de una expansión en terminos del conjunto de funciones ortogonales asociadas con los modos normales de la vibración del sistema. En base a los datos experimentales de Aupperle y Lambert y en la teoria generalizada se obtuvo la respuesta de desplazamiento, velocidad, momentos flectores, cargas de corte transversal y esfuerzos para una placa plana, rugosa rectangular simplemente apoyada. Los resultados son discutidos y comparados con los obtenidos por Strawderman para placas lisas. Finalmente, son presentadas sugereneias para futuras investigaciones. / The objective of this work is the determination of the response of a rough, simply supported, rectangular plate excited by a turbulent boundary layer. A general solution has been found for the displacement response of any randomly excited continuos linear system. The method of solution makes use of the generalized harmonic analysis and series expansions in terms of the set of orthogonal functions associated with the normal modes of vibration of the system. 0n the basis of experimental data of Aupperle and Lambert and of the generalized theory, responses were obtained for the displacement, velocity, bending moments, shear loads and stresses for a rough, simply supported, rectangular plate. The results obtained are discussed and compared with the ones by Strawderman for smooth plates. Finally, some suggestions are made for future research on the subject.
