The Application of Piezoceramics for Reducing Noise and Vibrations in Vehicle Structures

Automotive applications of active vibration control

“…In the case of ANC, this cancelling signal is generated through loudspeakers, whereas for AVC, force actuators such as inertia-mass shakers are used. Various authors have addressed the application of ANC and AVC systems to reduce noise and vibrations in automotive applications (Adachi & Sano, 1996), (Adachi & Sano, 1998), (Ahmadian & Jeric, 1999), (Bao et al, 1991, (Doppenberg et al, 2000), (Dehandschutter & Sas, 1998), (Fursdon et al, 2000, (Lecce et al, 1995), (Necati et al, 2000), (Pricken, 2000), (Riley & Bodie, 1996), (Sas & Dehandschutter, 1999), (Shoureshi et al, 1995), , (Shoureshi & Knurek, 1996), (Sano et al, 2002), (Swanson, 1993). ContiTech has implemented prototypes of AVC systems in various test vehicles and demonstrated that significant reductions in noise and vibration levels are achievable , (Karkosch et al, 1999), (Bohn et al, 2000), (Svaricek et al, 2001), (Bohn et al, 2003), (Kowalczyk et al, 2004), (Bohn et al, 2004), (Kowalczyk & Svaricek, 2005) (Kowalczyk et al, 2006), (Karkosch & Marienfeld, 2010).…”

On the Application of Shunted Piezoceramics for Increasing Acoustic Transmission Loss in Structures

“…Although other shunting concepts exist, this shunt circuit was chosen because it had successfully been used for other applications [18,19]. The basic resonant shunt design consists of a resistor, an inductor, and a capacitor.…”
