Abstract
The invention discloses an experiment method and device for simulating a music road design. A motor is arranged at the bottom of a support; an engraved groove sounding plate is arranged at the upper part of the support; a transmission shaft of the motor stretches out of the center of the engraved groove sounding plate and is connected with a telescopic cantilever; a simulation wheel is arranged at the top end of the telescopic cantilever and is in contact with the surface of the engraved groove sounding plate to form a rolling friction pair; and sound acquisition equipment is arranged above the engraved groove sounding plate and is used for detecting sounds generated when the simulation wheel rolls on the surface of the engraved groove sounding plate. The sounds generated when the simulation wheel rolls on the surface of the engraved groove sounding plate is acquired through the sound acquisition equipment, so that the depth and the width of engraved grooves and the distances between each two adjacent engraved grooves in the surface of a music road are established, the relationship between musical notes and relevant variables of the grooves is determined, and a music effect generated by intense sounds is designed. The device is simple in design and convenient to use, manufacture, install and operate, and can obtain an authentic simulation effect by freely adjusting experimental parameters such as vehicle speeds and the distances between each two grooves according to experiment demands.
Description
Technical field
The present invention discloses a kind of test method for analog music Road Design, additionally provides the device realizing the method simultaneously, for the acoustic simulation test of music highway, belongs to Road Detection equipment technical field.
Background technology
In the origin cause of formation statistics of various countries' road traffic accident, have sizable ratio all not concentrate relevant with driver attention, as fatigue driving, negligence, misjudgment, improper measures etc., these situations are even more serious on a highway.So, how from road safety technical standpoint, utilize certain sound to carry out driver in alarm car and concentrate on, reduce the important content that traffic accident that the reason such as dispersion attention, doze due to driver causes becomes the research of current traffic safety.Physical mechanics and highway engineering construction knowledge is travelled based on music theory, vehicle, and driving vehicle can send rumble through groove, and the sound that interval difference produces is also different, consider regular groove distance, vehicle travels they time will produce a series of high note or low note, therefore, the groove that a series of interval is not waited is engraved on road surface by designer---and " music highway " has just been born thus.Music highway can make driver hear, and the principle of music is mainly because driving vehicle can send rumble through groove, and the sound that interval difference produces is also different, according to melody melody, by design, some arrange regular groove distance to designer, make vehicle travels they time produce a series of high note or low note, thus make highway " performance " go out beautiful melody.
At present, cannot test in the music Road Design stage at highway solid, also not relevant simulation test device, brings very big inconvenience to designer.
Summary of the invention
The present invention discloses a kind of test method for analog music Road Design and device, and object is intended to for the acoustic simulation test of music highway.
The device of the test method for analog music Road Design provided by the invention, its technical solution is as follows:
Be made up of motor, sound collection equipment, cutting pronunciation board, power transmission shaft, telescopic boom, simulating wheel, bracing frame; Wherein,
Motor is provided with in the bottom of bracing frame, the upper unit of bracing frame has cutting pronunciation board, the power transmission shaft of motor stretches out from the central authorities of cutting pronunciation board and is connected with telescopic boom, the top device of telescopic boom has simulating wheel, and simulating wheel contacts with the surface of cutting pronunciation board formation rolling friction pair; Sound collection equipment is arranged on the top of cutting pronunciation board, detects the sound equipment that simulating wheel produces at cutting pronunciation board surface scrolls.
On the surface of described cutting pronunciation board, be carved with the groove that some Tiao Yi centers are axially outer radiation.
The course of work of the present invention is as follows: motor drives telescopic boom to rotate by power transmission shaft, telescopic boom drives simulating wheel to roll on cutting pronunciation board, the sound is issued out in the groove effect of cutting pronunciation board, simulated automotive is with the traveling of certain speed on groove road surface, gather air vibration in tire and groove by sound collection equipment and send the frequency size of specific sound, be based upon in vehicle travel process the frequency and groove depth of vibrating grand sound, width, the theory relation of spacing between adjacent cutting, and in conjunction with the accurate note frequencies table of comparisons, determine the frequency range that required note is corresponding, according to relevant music theory knowledge, the relation between note and groove correlated variables can be determined further, thus provide test foundation for the improvement and perfection of music Road Design.
good effect of the present invention is:by the sound equipment that sound collection equipment simulating wheel produces at cutting pronunciation board surface scrolls, set up spacing between the groove depth of music road surface groove, width, adjacent cutting, determine the relation between note and groove correlated variables, design the music effect that grand sound produces.Apparatus of the present invention simplicity of design, easy to use, be convenient to make, install and operation, the test parameters such as the speed of a motor vehicle, flute pitch can be regulated arbitrarily according to test requirements document, obtain simulate effect true to nature.
