Addressing this challenge, CryoTech has introduced an innovative and cost-effective micro-miniature split Stirling cryocooler featuring a single-piston compressor and a pneumatic expander, the vibration export of which has been effectively reduced at the source by substantially decreasing the weight of the moving assemblies. For vibration-sensitive applications, the authors provide an optional Tuned Dynamic Counterbalancer featuring a linear failure-free magnetic spring. This patent-pending solution enables not only a failure-free operation of a substantially lighter device but also leads to a substantial reduction in the damping ratio, thereby additionally enhancing the vibration attenuation ratio at the driving frequency. The authors provide a comprehensive overview of the outcomes derived from a thorough feasibility study, encompassing both theoretical analysis and full-scale experimentation. |
