Sažetak
Nano-positioning, being an integral part of almost every nanoscale operation, has been an intensely researched topic. For the purpose of providing linear and highly precise movements on nano scale levels, compliant mechanisms are often used in combination with piezoelectric drivers. Usage of the piezoelectric elements as actuators has numerous advantages, but their direct application is limited by their working stroke. Common solution is to include a stroke amplifier stage into the compliant mechanism in order to avoid this limitation. Due to different requirements for stiffness and flexibility in different parts of the compliant mechanism frame, different joint designs are used. This paper takes a different approach and research possibility of using multi- material frame of the mechanism in order to achieve high rigidity in selected areas. As recent advancements in additive manufacturing enabled production of composite materials, designs in this paper focus on geometry that is manufacturable by traditional manufacturing methods as well as additive manufacturing. The main focus of the research was to minimize internal loses of the amplification stage caused by unwanted material deformation in order to maximize efficiency. FEM simulation was used for this purpose in order to evaluate different material solutions.
