Description
Technical field
The utility model relates to the device that improves pressure measurement pipeline dynamic pressure measurement error.
Background technology
Dynamic pressure measurement is widely used in aviation, Wind Engineering and aeroacoustics. But, in actual pressure measxurement, often, due to the restriction of moulded dimension, the sensor of gaging pressure can not be directly installed in model cavity, but by one section of pipeline, pressure signal is transported to gaging pressure on sensor, the frequency response of pipeline itself has impact to pressure signal like this, if transfer conduit design is bad, when pressure signal process pipeline, resonate, signal produces distortion, the data error collecting will be very large, even can not get correct result. Therefore be badly in need of optimizing circuit design, study a kind ofly for improving the device of dynamic pressure measurement frequency response function, improve dynamic pressure measurement data precision.

The purpose of this utility model is to provide a kind of device that improves pressure measurement pipeline dynamic pressure measurement error.
For achieving the above object, the technical solution of the utility model is a kind of device that improves pressure measurement pipeline dynamic pressure measurement error of design,
Comprise cylindrical hard copper tube body;
The length of described cylindrical hard copper tube body is 30mm, and internal diameter is 0.8mm;
Described cylindrical hard copper tube body length direction middle part is crushed to form and flattens hard copper pipeline section;
The length of described flattening hard copper pipeline section is 5mm, and inner chamber thickness is 0.4mm;
Described cylindrical hard copper tube body, the termination at its length direction two ends, for a pair of for inserting the joint of outside pressure measurement pipeline;
Above-mentioned pair of joint is symmetrical arranged to flatten hard copper pipeline section.
Preferably, the end face of described joint is provided with chamfering.
Preferably, described pressure measurement pipeline is flexible pipe.
Advantage of the present utility model and beneficial effect are: a kind of device that improves pressure measurement pipeline dynamic pressure measurement error is provided, promotes measure data precision.
