Design and experiment of double-layer vibration isolation system for mobile vehicle-mounted optical platform

The paper analyzes the damages of shock and vibration to precise mobile vehicle-mounted optical systems during transportation process and working condition, points out that structural deformation and vibration are the main factors influencing optical system stability and vehicle installation implementation, and notes that it is the key technique to achieve the optical system stability by improving the overall vehicle stiffness, stability and vibration isolation performance of the mobile vehicle-mounted optical platform. The structure and composition of the vehicle-mounted optical platform as well as high stiffness and double-layer isolation design solutions are discussed. The modal analysis of the designed double-layer optical platform isolation system is carried out with ANSYS finite elem
