Abstract
An improved vibration isolation system utilizes at least one pair of structures connected vertically in series with each other and with a base structure and preloaded vertically, with a payload platform disposed between and connected to the structures. Each structure has a negative-stiffness effect in response to vertical compressive load for reducing its horizontal stiffness. The system passively accommodates changes in payload weight or weight distribution by providing a prescribed change in horizontal-motion isolator stiffness with change in weight load. The invention also provides an improved means of retrofitting existing vibration-isolating suspension systems to reduce their stiffness and increase their damping.
