Description
Technical field
The utility model relates to bullet train test with crosswind polyphasic flow system in combination parts, specifically the air-supply arrangement used of a kind of Special experimental.
Background technology
The bullet train test is nonstandard making with crosswind polyphasic flow system, and difficulty of processing is large, welding quality requires height, wind speed is high, noise is large, and air quantity is difficult for balance and distributes.
The utility model content
The purpose of this utility model is: provide a kind of cost lower, easy to process, the bullet train experiment crosswind system that noise is low is in order to detect the various parameters of train under simulation high-speed cruising state.
The purpose of this utility model realizes by following technical proposals:
A kind of bullet train is tested with crosswind polyphasic flow system, comprise many blower fan and Soundproofing static pressure boxes of being regulated by frequency converter in parallel, every Fans is communicated with described Soundproofing static pressure box by airduct separately, the air outlet of described Soundproofing static pressure box is provided with rectification section, described rectification section comprises air grille, honeycomb screen, and the linkage section that is communicated with both, described air grille is located at the air outlet place of Soundproofing static pressure box.
In the such scheme, Soundproofing static pressure box can maximize noise elimination, thereby reduces the strong noise when testing, thereby avoids experimental work personnel's discomfort.Air grille is set distributes air quantity, air grille bears Wind Volume, large pressure wind speed passes through, and can produce howling.Can avoid under the effect of rectification section and interior honeycomb screen thereof producing and utter long and high-pitched sounds.
As optimal way, described air grille is a reducing, cuts apart for the air uniform grid of square opening in it.
In the such scheme, the air uniform grid that square opening is set is cut apart, and adopts the checkering aperture to be combined into a large air port, and allocation of the amount of air is evenly maximized.
As optimal way, described Soundproofing static pressure box forms for horizontal at least two sections detachable head and the tail splicings.
In the such scheme, make a plurality of Soundproofing static pressure boxes effectively be combined into a large-scale Soundproofing static pressure box, so that the Soundproofing static pressure box dismounting, combined traffic.
As optimal way, described honeycomb screen stackingly fixedly forms by square tube is evenly distributed.
In the such scheme, adopt square tube processing, reduced difficulty of processing.
As further preferred embodiment, described blower fan is 10 parallel connections, and described square opening and square tube are 100*100mm, and the air port of described air grille is of a size of 12500*1000mm.
Workflow of the present utility model: many Fans also are unified into a system, can regulate the rotating speed of blower fan by frequency converter, every Fans enters into Soundproofing static pressure box by airduct separately, after eliminating the noise, directly send from the air port behind from the side the honeycomb screen, when the bullet train of test usefulness passes through air supply section, air-supply acts directly on the experimental run train, just can simulate the various operational factors that detect bullet train in state of nature.
The beneficial effects of the utility model: simple in structure, handling ease, cost be low, can be repeatedly used, better economic benefit, and noise is little in the system test process, allocation of the amount of air is even, and blower fan can variable frequency adjustment air quantity wind speed.System's soundproof effect is good: the noise of equipment is at 108 decibels, and through Soundproofing static pressure box, after basement was eliminated the noise, equipment at last will be about 80 decibels at the noise on ground.Knockdown Soundproofing static pressure box can disassembled for transport effectively be saved the testing laboratory space to other storeroom after experiment finishes.
