La síntesis de mecanismos planos representa un problema atractivo para ser resuelto mediante técnicas de computación evolutiva, ya que ésta plantea un sistema indeterminado de ecuaciones no lineales cuyo tamaño es directamente dependiente del número de puntos de precisión definidos para describir la trayectoria deseada del acoplador. Este artículo presenta la optimización en el proceso de síntesis de mecanismos basado en algoritmos genéticos (AG) para el caso de un mecanismo plano de seis barras tipo Watt utilizado como base para el diseño de una prótesis policéntrica de rodilla. La trayectoria deseada a ser descrita por el acoplador corresponde a la descrita por la rodilla durante un ciclo normal de marcha. La metodología propuesta ilustra claramente como, por la aplicación de AG’s, la trayectoria generada evoluciona de manera natural desde una solución errática hasta una curva que se ajusta suavemente a la trayectoria deseada.Descargas
