ИССЛЕДОВАНИЯ ЗВУКОИЗОЛИРУЮЩИХ МАТЕРИАЛОВ В СЕЛЬХОЗМАШИНОСТРОЕНИИ НА РОБОТИЗИРОВАННОМ СТЕНДЕ

Abstract

The article provides information about a stationary robotic stand designed for experimental research, a description of the operation of this stand is given. A feature of the stand is the implementation of a research facility with the possibility of programmatic research without the obligatory presence of a researcher. A remotely controlled power amplifier, a remotely controlled sound generator and a personal computer with special software are used. The sound source is located close to one of the end walls of the soundproof chamber. The sound receiver in the form of a high-precision microphone is located on the opposite end wall of the soundproof chamber and is connected to the sound processing module, which is connected to a personal computer. The developed stand is an example of the concept of robotic research, a direction for improving the methodology of research work. A description of the design of the stand is given; information about known similar research equipment is given. A scheme of the stand and a description of its design are given. Some results of studies of soundproof materials are given. The effect of the structure of soundproofing materials on the frequency characteristics of acoustic impedance is shown. The essence of test bench automation lies in programmatic change of research modes for each experiment. The robotic stand ensures the reliability of the results of experimental studies, allows you to speed up the results.
