  • dc.description.abstract
    Measuring mechanical admittance (velocity over force) is a relevant method for analysing the vibration characteristics of mechanical systems. This generally involves exciting the structure with a known force and measuring the resulting acceleration using suitable sensors. The vibration is usually excited either by a shaker using a sinusoidal input force (sine sweep) or by an impact hammer using a force pulse. Depending on the hammer size and the object being measured, it is very difficult to reproduce excitations by hand. Therefore, it has become standard practice to stabilise the impulse hammer by suspending it like a pendulum. If the excitation is also to be automated, the pendulum assembly can be expanded to include a stepper motor. Commercial systems tested by the authors are expensive and, due to the loudness of the drive motor, are not suitable for acoustic measurements. This paper presents a relatively simple method for implementing an automated impact hammer system using commercial measurement technology and audio components. In addition to design proposals, the paper also discusses first measurement results and the potential for further development.
