Translational springs are employed to generate desired force-displacement relationships. Conventional translational springs utilize elastic deformations of coiled spring strips to fulfill their functions. The two-dimensional output motion of a conventional translational spring is produced by the three-dimensional deformation of its coiled spring strip, which is bending plus twisting of the coiled spring strip. Different from conventional translational springs, flexure based translational springs have simple planar monolithic structures and are convenient to manufacture and maintain. The output translation of a flexure based translational spring is from the two-dimensional bending of its planar flexible members. This thesis research is focused on synthesizing flexure based translational springs. The flexure based translational springs are synthesized in this research to generate large output translations with desired constant spring stiffness rates and without parasitic output translational drifts. Because of large deformation and geometric nonlinearity, the existing flexure based translational springs face difficulties that include spring stiffness deviation, parasitic output translational drift, and high stress in the deformed springs. This thesis research is motivated by surmounting the difficulties. The arrangements of flexible beams in a flexure based translational spring are analyzed. A method for synthesizing flexure based translational springs is presented. The method is demonstrated by synthesizing flexure based translational springs with different beam arrangements.
