【 摘 要 】

The aim of this study is to visualize the dynamic vibrating basic system, active element and sensors transmitting the current state of the system. The paper presents the use of piezoelectric accelerometers as vibration sensors used in active vibration reduction. In active vibration reduction, apart from actuators, there are also necessary elements with which it will be possible to continuously test and measure vibrations. It is necessary that the active element generates sufficient force to reduce unwanted vibrations. The selection of active elements reducing vibrations and sensors transmitting the current state of the basic system is presented. Due to such a comprehensive approach, it is possible to obtain a model of the system that will have the desired properties at the design stage. It will also be possible to select an appropriate subsystem using which it will be possible to eliminate the harmful effect of vibrations on the basic system.
