To suppress vibration during robotic grinding of aero-engine blades caused by low stiffness and point-to-point movement, a novel metamaterial comprising double-nested auxetic structure local resonator is proposed. It simultaneously achieves enhanced-stiffness an ultra-low frequency wide-range band gap generated the hybrid auxetic-locally resonant characteristic. Young's modulus studied analytically numerically. A co-simulation procedure applied to obtain optimized (the bottom boundary 18.03 Hz) based on modal analysis results, verified through experimental study. The design nested provides effective strategy for suppressing vibration.
