Investigation of Multifunctional Actuators on an Air-Cushion

Abstract

This paper analyses the area in which synchronic operation of several pneumatic actuators connected by a rigid link exists. The minimum values of the supplied compressed air have been determined under which self-exciting vibrations appear in the system of several actuators. The influence of the transducers geometrical parameters on the variation law of motion of the system working organ has been investigated. It has determined that character of dependencies of peak-to-peak and frequency upon pressure of system is similar to character of dependencies separate transducer and that having picked up geometrical and dynamic parameters actuators it is possible to receive difficult (biharmonic) movement of system. This property can be applied in vibrostands meant for material or equipment trials and their vibrational processing.
