A torsional vibration damper includes a planetary gear set having a ring gear connected to a transmission input shaft, a carrier rotatably supporting multiple planet gears individually meshed with a sun gear, and with the ring gear meshed with the planet gears. A spring cage includes a first spring support member having: a member first leg fixed to the ring gear; a member second leg rotatably connected to the transmission input shaft; and multiple first spring support member elements. A second spring support member connected to the carrier, the second spring support member having multiple second spring support member elements. Multiple springs each spring have at least one of the first spring support member elements and one of the second spring support member elements in contact with opposed ends of the spring. An inertial mass member is connected to the sun gear at a first end and has an inertial mass connected at a second end.
