Description
Technical field
The present invention relates to a kind of vibration absorber, more specifically, more particularly to a kind of damping shock absorption component.
Background technology
Noise pollution is regarded as four main Environmental Problems in world wide with water pollution, atmosphere pollution, waste pollution.
Since Industrial Revolution, the creation of various plant equipment and use, brought to the mankind flourishing and progressive, but also generate simultaneously more
Carry out more and increasingly stronger noises.The measure taken to reduce noise is mainly sound insulation and absorbs sound, but so far
A kind of method for not finding low cost and excellent noise reduction effect also.
By taking traffic noise as an example, the track traffic mode such as subway, light rail is the important mode of transportation in many cities in the world,
With convenient, fast, punctual, handling capacity of passengers it is big, energy consumption is low, pollution is light, take up an area many technology economy advantages such as good with security less,
It is the primary selection for solving the problems, such as city traffic, the track traffic such as development subway, light rail has turned into the hair of China's urban transportation
Exhibition direction.With the continuous improvement of people's living standard, environmental consciousness is increasingly strengthened, to the running environment and ride comfort of train
Property proposes requirement higher.Because excessive noise will have a strong impact on the psychology of people along passenger and track, physiology and just
Often life, therefore, the noise characteristic of subway is into an important indicator for weighing ground weight of iron.American Public Transit Association formulates
Urban track traffic Noise measarement index be：The acceptable noise of in-car is 70~80dB；In standing maximum noise should be 75~
85dB；The higher limit of roadside noise is 70dB in residential block, is 85dB in industrial area (in the line at heart line 15m).Its noise
Level index can be determined with ensuring private conversation at 0.35m so that normal sound is carried out.
In railway traffic engineering, generally using the kind of drive of orthogonal variable voltage variable frequency, the mode of braking of vehicle is electric braking
(regenerative braking)+mechanical braking, in operation based on electric braking, supplemented by mechanical braking.Train in the process of running, due between station
Away from shorter, launch train, braking are frequent, and braking energy is considerable.Rule of thumb, subway regenerative braking produce energy except
Certain proportion (generally 20%~80%, according to the different and different of train operation density and zone distance) is by other adjacent trains
Outside absorbing, remainder will be consumed mainly or by the absorption dress on circuit by the absorption resistance of train in the way of generating heat
Put absorption.Rail vehicle electric braking has two types, and a class is vehicle self-carrying braking resistor, and a class absorbs for ground regenerative braking
Equipment.Wherein mixed type braking energy absorption equipment mixes consumption braking energy using resistance, is a kind of ripe with advanced combination
Degree application high, the safe and reliable coefficient of longtime running is high, and maintenance is few.With the development of society, what environmental improvement was required carries
Rise, operating resistance noise grade is lowered the requirement urgently, and both at home and abroad accordingly braking resistor noise grade 75dB with
On, particularly operation is arranged on circuit periphery open air and platform operation interval to appliance arrangement mostly, Working Life is lived and is produced
Influence.Urban development proposes the new application demand of the high-power braking resistor of low noise, and resistance noise reduction technology application meets environment life
The demand that state is continued to develop.
High-power resistance and underground railway track vehicle braking resistor are usually resistor box case, average equivalent power 160kW~
220kW/ faces (are simultaneously usually 6~8 resistor box casees), and what is passed through is the copped wave direct current of IGBT Switching Power Supplies treatment.Copped wave
Pulse power frequency is general interval in 150Hz~300Hz, and psophometric electromotive force higher is produced to apparatus, and copped wave pulsation is big
Direct current causes resistance grid heating to produce Vibration propagation noise, and the size or power of noise depend mainly on the amplitude of object vibration,
Amplitude is big, and noise is big；Amplitude is small, and noise is small.Vibration is caused by molecular agitation, and the frequency band to resistance value, temperature and the external world is related,
Be directly proportional to applied voltage electric current, noise size also with structure direct correlation, power it is bigger accumulation superposition noise it is bigger.Specifically
For, because track traffic operating temperature is generally between 200~550 DEG C, to reduce operating temperature, the development trend of resistance grid
For thin, long, big, the resistance grid that the present invention is provided is thin slice band structure long, is to obtain atomic inductance and excellent ventilation dissipates
Heat, it is arranged in parallel using long wave.Braking the argument structure of (power) resistance has corresponding standard to specify, it is difficult to flexible, accordingly into
This control and economic feasibility, also have a considerable restraint to improvement, and lamelliform resistance waveform configuration, in hot operation due to
Influenceed by the electrothermal alloy coefficient of expansion, the micro elongated bending of meeting in a waveform increases electromagnetic exciting effect, adds cold and hot sky
Gas forms strong pressure difference, and the energy that it is resistance noise that convection current fluctuation causes superpositing vibration is originated.Waveform quantity is more, and surface area is big,
The strip rigidity of structure is poor.The superposition of high-power resistance cabinet case is installed concentratedly, and accumulation necessarily leads to big noise.Generally speaking, track
Traffic is typically the vibration that front end power supply IGBT copped waves pulsation heavy current impact causes during by working, the heat of cold and hot exchange during work
Hot-tempered disturbance, vibration that resistance grid chip architecture causes and trigger noise.
According to existing Noise Prevention and Treatment mode, control the noise of resistor box case apparatus, generally set outside appliance arrangement every
Sound board wall, can increase taking up room for equipment, uncoordinated with environment；Or in the resistor box high-power filtering of case pre-configured, its
Pulsation of current noise can be reduced, heat is made an uproar also and existed, and preposition high-power filter unit cost is high big with volume, occupies preciousness
Accommodation space, still cannot function as preventing and treating the optimal selection of noise.Other prior arts are also due to product standard rule is limited.
