The principle of this utility model foundation is: Doppler effect is pointed out, ripple receives frequency and uprises when wave source shifts to observer, and receives frequencies go lower when wave source is away from observer.About in Doppler effect, frequency that wave source sends, the frequency that observer receives, the speed of wave source, the relation such as speed of observer, it is the scientific knowledges that already are familiar with of the mankind, if this specification has the misrepresentation violating Doppler effect rule, should be correct conclusion with the result that Doppler effect rule is derived, and such conclusion is beyond all doubt available conclusion, and such amendment should also be as being allowed.
When this utility model uses, dolly is placed in the initiating terminal of swash plate track, connect the power supply of dolly sonic generator, sonic generator sends the acoustic signals of fixed frequency, acoustic receiver receives this acoustic signals and transfers the signal to the controller, when dolly is static, the fixed frequency that the acoustic signals frequency that acoustic receiver receives sends with sonic generator is equal, controller controls height-regulating mechanism and is risen by the initiating terminal of swash plate track, until dolly starts to move along swash plate track, in order to express easily, sonic generator is here made to do the motion away from acoustic receiver, according to Doppler effect, hereafter controller receives the fixed frequency that acoustic signals frequency sends less than sonic generator.If little vehicle speed is increasing, then, the frequency of sound wave that acoustic receiver receives will be more and more less, if little vehicle speed is more and more less, then, the frequency of sound wave that acoustic receiver receives will be increasing.Little vehicle speed is increasing, illustrates, inclination angle is big, needs to turn down, and namely controller controls height-regulating mechanism and reduces the initiating terminal of swash plate track；Little vehicle speed is more and more less, illustrates that inclination angle is little, needs adjustable inclination to become big, and namely controller controls the initiating terminal of height-regulating mechanism lifting swash plate track；If little vehicle speed is constant, then, the frequency of sound wave received is also the most constant.Dolly is in motor process, and the frequency of sound wave that acoustic receiver receives is constant, it is meant that inclination angle need not have adjusted.It is emphasized that: the frequency of sound wave received in motor process is constant, rather than when dolly is static, frequency is constant.Both is constant, has what difference？Difference is: receives frequency in motor process constant, receives the frequency of sound wave that frequency necessarily sends less than sonic generator；When dolly is static, the frequency that the frequency that acoustic receiver receives sends equal to sonic generator.
The preceding paragraph word, illustrates the wave source situation away from observer, and according to the scientific knowledge of Doppler effect, those skilled in the art should know the wave source situation near observer.Here wave source is exactly sonic generator, and observer here is exactly acoustic receiver.
The when of slope track level, dolly is unlikely to be at the uniform velocity, so, dolly can not be by the end autonomic movement of slope track to initiating terminal.
Sound wave can be infrasonic wave, such as the frequency of 4Hz, 5Hz.Can also be human ear audible sound wave, such as 40Hz, 400Hz, 4000Hz, 50Hz, 500Hz, 1000Hz, 2000Hz, the frequency of 5000Hz, 6000Hz, 7000Hz, 8000Hz, can also be ultrasound wave, such as 20000Hz, 22000Hz, 23000Hz, 24000Hz, 25000Hz, 26000Hz, 27000Hz, 28000Hz, 29000Hz, 30000Hz.Preferably ultrasound wave, because ultrasonic technology comparative maturity, and generation diffraction more more difficult than infrasonic wave.Here frequency of sound wave can also be above-mentioned certain numerical value determined in point value scope, because numerical value has infinite multiple, it is impossible to list one by one.
The beneficial effects of the utility model include: 1, and regulation is quickly.2, degree of regulation is high, 3, can while moving of car adjustable inclination.4, shorten the time used by regulation, decrease regulation number of times.No matter it is theoretical, or actual measurement, so regulate, higher than the mode precision of " adjusting once will survey once again ".5, dolly initial velocity need not be given.
Certainly, the detection of frequency of sound wave is also had certain frequency, current technology, can be the highest to the detection frequency of frequency of sound wave, the highest detection frequency, the most sufficiently high.
The content stated based on utility model content, the title that this utility model is created can also be: kinetics track based on Doppler effect, kinetics research device based on Doppler effect, kinetics track based on acoustics, kinetics research device based on acoustics, the method of institute's utility model, it is also possible to be named as: the method obtaining uniform motion based on Doppler effect, a kind of method adjusting track for research kinetics.
