8-7 Diseñe una leva de doble detenimiento para mover un seguidor de 0 a 2.5″ en 60°, detenimiento durante 120°, bajada de 2.5″ en 30° y detenimiento en el resto del movimiento. El ciclo total debe tomar 4 s. Elija funciones adecuadas de subida y bajada para minimizar las aceleraciones. Trace los diagramas s v a j.
La función más adecuada para minimizar aceleraciones son las ecuaciones de “movimiento armónico simple”
