Abstract A novel piezoelectric shunt damping methodology for structures featuring different mode families with high modal density is introduced in this work. To end, multiple digital vibration absorbers comprising each a voltage sensor, processing unit and current injector are connected to transducers bonded these structures. The mimic multi-stage blocking circuit whose parameters determined se...

Equivalent Static Wind Loads (ESWL) are desired in structural design to consider peak dynamic wind effects. Conventional ESWLs for structures without control. For flexible with vibration control devices, the investigation of ESWL is required. Inerter-based Vibration Absorbers (IVAs), due light weight and high performance, gained much research attention recently. This paper established a generic...

An anchor drilling for a coal mine support system can liberate an operator from heavy work, but will cause serious vibration, which willbe transmitted to the pedestal roof bolter along manipulator. Based on multi-level transfer path analysis (MTPA) and modal superposition method (MSM), vibration model subsystem composed of joints manipulator with six degrees freedom (DOF) was established. Moreo...
