Active control of structural modal vibration is an effective strategy to enhance the sound quality cabs in commercial vehicles. However, accurate determination positioning and quantity active sensors actuators crucial for with intricate structures, owing presence multiorder modes their coupling. The study presented herein focuses on cab a vehicle contemplates features irregular large-space structure cab. By capitalizing frequency mode shape cab, utilizing piezoelectric principle energy as assessment index, advanced multimode composite criterion postulated ascertain configuration primary actuators. particle swarm optimization (PSO) objective function constructed accomplish optimal position matching actuator/sensor, using multimodal surface velocity vector sensor core parameter. Furthermore, improved linear adaptive (LA-PSO) technique satisfy requirements convergence performance accuracy complex structure. culminates 9 × multichannel scheme determining actuators/sensors. This investigation provides technical foundation automotive presents innovative method implementing noise systems large-scale machinery equipment.
