Design of a mechanical system for vibration isolation

Mechanical vibration has a great influence on the design of mechanical system. Mechanical systems often need to design a reasonable vibration damping mechanism to maintain the normal operation of the mechanism the compliant mechanism has good guiding accuracy and cushioning stiffness. Through the analysis of the actual cushioning problem and the structural topology of the existing traditional, compliant unit, this paper selects Roberts four-bar mechanism as the primary design scheme of the respectful team, obtains the basic configuration of the extended compliant unit through the stroke expansion deformation of the selected mechanism, and carries out the stiffness modeling and analysis of the basic configuration unit of the compliant mechanism, to obtain the stiffness performance. Finally, the structural and element verification optimization is carried out according to the designed compliant mechanism. The central performance verification is carried out through FEA (finite element analysis) simulation. The results show that the designed mechanism has good stiffness buffer performance and meets the design requirements.
