Abstract

The invention relates to the technical field of acoustic resistance material testing, in particular to an acoustic resistance material testing device which comprises a plurality of acoustic resistancetubes, a sliding pair, a feeding device, an acoustic absorption cotton adjusting sliding rod and a fine adjusting bolt. The acoustic resistance tubes comprise a head end acoustic resistance tube anda tail end acoustic resistance tube; the sliding pair comprises a sliding block and a sliding rail, and the sliding rail is installed on a supporting device through an installation plate and bolts. The feeding device is mounted on the sliding rail; the tail end acoustic resistance tube is installed on the supporting device and located on one side of the sliding rail. The sound absorption cotton adjusting sliding rod is installed in the tail end acoustic resistance tube and provided with a scaleplate. The fine adjusting bolt is connected into the counter bore of the sliding block in a screwed mode and located on the side close to the sound absorption cotton adjusting sliding rod, and the fine adjusting bolt and the sound absorption cotton adjusting sliding rod are coaxial. Linear feeding isachieved through the feeding device, motion can be directly transmitted, no transfer device is needed, reverse motion is avoided, testing steps are simplified and the accuracy of testing results is improved.

Description

technical field [0001] The invention relates to the technical field of acoustic resistance material testing, in particular to an acoustic resistance material testing device. Background technique [0002] The acoustic resistance material tester is an instrument used to test the acoustic properties of materials, and plays an important role in the analysis of acoustic materials. Acoustic material testing can be used to characterize material-related uses, obtain specific material properties, test and evaluate manufacturing quality, and this information can be used for teaching. [0003] Acoustic material testing can determine material properties by exposing test pieces to production and measuring their effect on production. Different needs and test conditions require different methods to measure. For this reason, corresponding test conditions and specific equipment have been developed according to national standards to ensure high repeatability and reproducibility. [0004] T...
