Title: VIBRATION SUSPENSION SYSTEM
Abstract:
A bi-directional spring member (110) is mounted to a support platform (115), the bi-directional spring member (110) being coupled to a payload (116). The bi-directional spring member (110) includes a non-linear spring (100) component having a rigid member (15, 16) enclosing at least a portion of a compliant planar member (10) and a linear spring component (90). The compliant planar member (10) flexes in a direction opposite a direction of low amplitude vibrational forces acting on the compliant planar member (10) to reduce vibrational forces acting on the support platform (115) and the linear spring member (90) flexes to reduce high amplitude vibrational forces acting on the support platform (115).
