Description
Technical field
Field is tested the present invention relates to water environment, the experiment more specifically to a kind of simulation lake wave agitation is filled
Put and experimental method.
Background technology
Wave of the sea is the wave propagated along the interface between water and air, and restoring force is provided by gravity, therefore it
Be commonly referred to as surface gravity wave.Wave in deep water typically has constant wavelength.When wave and seabed interact
When, it starts " shoaling ".Typically, this half for occurring to become the wavelength than wave in depth is also shallow, wavelength shortens and ripple
When width increases.When wave amplitude increases, due to the crest of wave is mobile must be faster than trough, so wave may become unstable.When
When wave amplitude is about the 80% of water depth, wave starts " to crush " and we carry out surfing.This rises and shattering process takes
The certainly characteristic of the deep water wave in the inclination angle at seabeach and profile, wave close to the angle at seabeach, the depth of water and close to seabeach.By right
The change of bottom configuration, the refraction and focusing of these waves are possible.
Wave typically has five stages：Produce；Propagate, aufhellung, crush, and decay.In general, wave can be shown
Cause the feature of one of four kinds of main broken sea types：Overflow, be involved in, collapse；With surge, various systems and technology are attempted artificial
Wave is replicated in environment.Some in these systems include conducts fast motion, relatively shallow sheet of water impact modelling Cheng Bo
The solid of shape can be multiplied with the producing but actually not water effect of wave.Other systems utilize linear activated oar, hydraulic pressure
Or pneumatic sluice or spray to produce actual wave just with big controlled water.However, all these systems are being incited somebody to action
Energy conversion is all that efficiency is low into " wave " aspect, due to a variety of causes and shortcoming, neither one is gone back in these systems and is approached
Produce such wave, the wave is replicated by looking for so as to required size, waveform, the speed of the optimal wave that are multiplied by
With it is broken, the wave is into the shallow water declined, is broken into the wave of tubulose, the wave have the relatively long duration and
The face that enough surfers are acted.
When being needed in modern times experiment to dystopy culture sample, it is desirable to sampled point true environment is simulated, such as bed mud
, it is necessary to which the environment of the air reaeration under truly simulation lake ripple is acted on, is the weight of bed mud property in dystopy culture, property testing experiment
One of influence.Therefore it is required for testing that wave simulation is carried out to experimental provision.
Through retrieval, patent No. ZL 201410171156.6, publication date August in 2014 13 days discloses a kind of wave and lake
Flowing common action Imitating bed mud corrodes the water tank device with transmission feature, including draws unrestrained passage and rough-water test pond, draws wave
Passage introduces wave and by drawing the wave formation rough-water test pond that unrestrained passage is introduced, drawing interior be provided with of unrestrained passage can manufacturer
The ripple of making of work wave is put, and is made ripple pendulum bottom and is provided with swinging axle, makes ripple swing set on swinging axle, both are brought into close contact, energy left and right is put
It is dynamic to form artificial wave.The present invention reaches the purpose realized without setting up large scale experiment room and make ripple experiment, adjustable weight
Make ripple ornaments meter and can arbitrarily adjust and make ripple pendulum counterweight and its intrinsic frequency is changed, so as to manufacture different frequency as needed
With the wave of amplitude.Secondary is to be converted into mechanical energy using electric energy, forms plug-flow, wave is formed in tank, so readily available
Bed mud corrodes the experimental result with transmission feature, but the assembling of this patent is complicated, and cumbersome, this experimental provision can not be simulated
Go out the phenomenon of irregular three degree of ripples of lake ripple.
Retrieved again, patent No. ZL 201420208166.8, publication date on October 22nd, 2017, disclose one kind
The manufacture wave device of Non-energy-consumption, inventor is permitted snowy peak et al..Including drawing unrestrained passage and rough-water test pond, drawing unrestrained passage will
Wave is introduced and by drawing the wave formation rough-water test pond that unrestrained passage is introduced, drawing interior be provided with of unrestrained passage can manufacture of intraocular wave
Make ripple pendulum, make ripple pendulum bottom be provided with swinging axle, make ripple swing set on swinging axle, both are brought into close contact, can swing to be formed
Artificial wave.The present invention reaches the purpose realized without setting up large scale experiment room and make ripple experiment, and the ripple of making of adjustable weight is put
Design, which can be adjusted arbitrarily, to be made ripple pendulum counterweight to make its intrinsic frequency change, so that manufacture different frequency and amplitude as needed
Wave.It is mainly characterized by without applying energy outside, using the effect of wave plug-flow, ripple pendulum dress dexterously is made by pendulum model for this patent
Put, wave is introduced in large-scale tank, realize the plug-flow situation of wave, but this experimental provision is applied to the examination of big kohoona
Test in device, and the putting position of its experimental provision must lean on sea, be relatively specific in fact in the experiment of the class of model ship one.
