Abstract:

A suspension system for a vehicle includes a frame, a wheel support member, a leaf spring secured to the wheel support member, a first connector for first pivotally connecting one end of the leaf spring to the frame, a torsion spring having a central shaft, an outer housing and an elastomer disposed between the central shaft and the housing, and a lever for pivotally interconnecting the central shaft with the other end of the leaf spring. The torsion spring is located between the leaf spring and the frame so that compression of the leaf spring causes the lever to be displaced rotationally toward the vehicle frame.

Abstract:

Systems and methods for acoustic windows are disclosed. An acoustic window may include a structural core and a non-structural tuning layer. The structural core may include a carbon reinforced composite, and the non-structural tuning layer may include an epoxy. The structural core may have local minima for insertion loss. The epoxy may increase a bandwidth about the minima of frequencies which are subject to relatively low insertion loss.
