Abstract
The utility model relates to an acoustical material settling bracket for a standing wave tube, and aims to solve the problem of uncertainty in the settling position of an acoustical material sample piece in the conventional standing wave tube experiment. The settling bracket comprises a handle, a push rod, a head cover, a bolt and an acoustical material positioning bracket, wherein the handle is positioned at the tail end of the push rod, is connected with the push rod in a threaded manner, and is driven to move by the operation of the handle; the push rod is slender and provided with accurate size scales in order to accurately judge the position of the positioning bracket inside a standing wave tube barrel; the discoid positioning bracket is in threaded connection with the other end of the push rod, is in parallel to the cross section of the standing wave tube barrel, is used for positioning the acoustical material sample piece, and ensures that the acoustical material is perpendicular to the standing wave tube barrel. The settling bracket has the function of accurately positioning a testing sample piece in the standing wave tube, and ensures the accuracy of the measurement result in experiment.
Description
Technical field
The utility model relates to a kind of standing wave tube acoustical material exemplar laying bracket.
Background technology
At present, when acoustics packing is optimized in to car, need to measures the acoustics parameters of different acoustical materials, and generally adopt standing wave tube to measure these acoustics parameters both at home and abroad.In process of the test, acoustical material exemplar need to be placed in to standing wave tube inside, due to problems such as the installing space in physical characteristics and the pipe of acoustical material itself limit, and current method exists riding position inaccurate, and the acoustical material exemplar of laying and standing wave tube xsect are not parallel.This will cause test result inaccurate.Tradition setting method is first to lay acoustical material exemplar, stretch into by ruler the riding position of measuring acoustical material exemplar in pipe again, this method is measured inaccurate, be difficult to determine that whether test specimen installation site is completely parallel with standing wave socket xsect, measuring process inexactness, certainly will affect the precision of the result of test like this.
Utility model content
Existingly there is the inaccurate problem of acoustical material exemplar riding position carrying out acoustical material characteristic test when test in order to solve in the utility model, a kind of standing wave tube acoustical material exemplar laying bracket is provided.
Standing wave tube acoustical material laying bracket, comprise positioning disk, push rod, end cap and handle, one end of described push rod is connected with positioning disk through end cap, push rod is provided with scale and stretches into the position of standing wave tube for determining push rod, and described end cap is provided with dog screw, for fixing push rod, the other end of described push rod is connected with handle, by controlling the position of push rod in standing wave tube socket, control the position of positioning disk in standing wave tube, realize determining of to the acoustical material position in standing wave tube.
The beneficial effects of the utility model: the utility model provides a kind of standing wave tube acoustical material exemplar laying bracket, this device has played riding position in standing wave tube of exemplar while guaranteeing test and has kept its direction and the effect of standing wave tube socket transverse cross-section parallel.Guarantee measuring accuracy; Have the following advantages: one, simple in structure, be convenient to processing; Two, can accurately locate acoustical material and put into the position of standing wave tube, guarantee that the exemplar of laying is parallel with standing wave tube socket cross section.
