COMPLIANT MECHANISM TOPOLOGICAL OPTIMUM DESIGN BASED ON TRUSS-LIKE CONTINUUM

Compliant mechanisms can transfer or transform motion, force or energy by deflection of flexible members. Compliant mechanisms need fewer parts, less assemble time and simple manufacturing processes. They have less wear, high precision and reliability. Compliant mechanisms can be designed on the traditional rigid-body kinematics [1] or on the topology optimization method of continuum structures [2] . This paper investigates the design method of compliant mechanisms by topology optimization method of continuum structures. The truss-like anisotropic continuum is adopted as material model [3] . The elastic matrix can be expressed by,
