Resumen
En este trabajo de investigación sé realiza una comparación de los resultados obtenidos con el software de SolidWork para el análisis de frecuencias naturales de una viga de ancho de 38 mm espesor de 3 mm y longitud de 400 mm de aluminio 7075-T6, para lo cual es fundamental determinar los primeros 4 modos de vibración, para esto se usaron cuatro diferentes métodos, como; las ecuaciones de Euler-Bernoulli para vigas empotradas, software comercial Ansys, NX 12 y en forma experimental, se observó que el promedio de error entre los resultados de
SolidWorks con los teóricos el promedio fue de 0.76 y la desviación estándar de 0.04 con el experimentales fueron del orden de 1.08 y 0.40, mientras que los resultados obtenidos con Ansys fueron 0.42 y 0.02 y NX 12 fueron del orden 0.01 y 0.01, por lo cual se comprobó que el uso del Software de SolidWorks es acto para realizar análisis de vibraciones mecánicas de forma rápida y confiable.
