ABSTRACT:
A bellows structure for use in high velocity, linear motion applications and which incorporates self-damping is disclosed. The bellows structure utilizes a plurality of thicker convolutions at each end of a regular bellows section to join the bellows section to its terminations. The thicker convolutions are distributed asymmetrically with the greater number of thicker convolutions being placed adjacent the stationary end of the bellows. The bellows structure increases the energy absorption capabilities of the stationary end of the bellows, and causes the intersecting, energy-absorbing waves traveling through the bellows section to intersect more frequently resulting in their internal cancellation.
