Description
Technical field
The invention belongs to technical field of transportation, relate to a kind of high speed train wheel, particularly relate to a kind of high speed train wheel with bionic non-smooth surface.
Background technology
The development of high speed train, providing convenience to people, while quick, comfortable transport services, also proposes new requirement on train to the impact of environment and the quality safety of itself.
The meeting of train when running at high speed between wheel and wheel track produces ear-piercing noise, this mainly by train wheel with interorbital impact, contact, friction causes.Flourish especially along with China Express Railway cause, improving constantly of train operation speed, train also constantly increases at traveling process wheel and wheel track Contact noise, causes impact, reduce the quality of the life of subjective reflection to the resident living near railway line.The noise reduction technology of wheel is also the important technological problems that train needs to solve in development.
In order to the noise produced between wheel track when reducing train operation, scholar both domestic and external and engineering staff propose countermeasure, and achieve certain effect.Specifically there is following several method:
(1) wheel surface smears damping material
Train wheel disc surface smear damping material can intercept the vibration of train disc by actv., thus reduces the noise because wheel mechanical vibration produce.But only have certain effect to frequency at more than 2KHz high frequency noise by the method reducing noise at spoke surface smear damping material, for the noise of frequency at below 1KHz, the effect of its noise abatement is not obvious.
(2) employing has elastomeric wheel
Elastic wheel is the noise reduction mode that the outer train of Current Domestic generally adopts, and has plenty of damping block inside wheel rim, has plenty of and install elastic damping sheet on disc, also have plenty of and add rubber ring between wheel rim and disc.Elastic wheel complex structure, productive costs is higher, and rubber ring is easily aging, and safety in operation is poor.
(3) shape of wheel is changed
The noise that train wheel produces is relevant with the shape of wheel, and the noise that the noise that oblique spoked disc wheel produces produces than S shape spoked disc wheel is large, and the noise that straight spoke type wheel produces is minimum.According to analysis, mainly because the stressed symmetry on the rolling contact point both sides of straight spoke type wheel, the power that tread transmits directly is passed on axle, guarantee that the load relative orbit contact on wheel can be symmetrical, thus reduce shaking the head of wheel rim, add the rigidity in radius of wheel direction.For manufacturing and the consideration of cost, changing wheel shape and being difficult in practice promote.
Along with the raising of high speed train speed and freight volume, carry whole car body weight and to communicate the wear-resistant and anti-fatigue performance of the tractive force of locomotive and the train wheel of braking force just more aobvious outstanding.According to North America rail transportation system statistics, the annual wheel changing tread damage nearly 1.5 hundred million dollars with regard to cost.And the Dalian locomotive works of China are only in first half of the year calendar year 2001, the wheel cost of process tread damage is just up to more than 2,700 ten thousand.As can be seen here, the resistance to abrasion and the fatigue resistance that improve train wheel are problem demanding prompt solutions.
In order to improve the service life of train wheel, must reduce fatigue and the wearing and tearing of wheel to greatest extent, scholar both domestic and external and engineering staff propose countermeasure in this, and achieve certain effect.Specifically there is following several method:
(1) wheel lubrication
In order to reduce the friction coefficient in tread face, wheel rim trackside lubrication is usually adopted to alleviate wearing and tearing.According to the feature of wheel rail system, lubrication form can only be boundary lubrication usually.By the effect of the 3rd medium, form boundary lubricant film, thus reduce sliding resistance, reduce the wearing and tearing of wheel surface.The effect of wheel lubrication anti-attrition directly depends on lubricant properties.There is pollution tread by the mode of lubricating oil anti-attrition, bring out the defect of idle running, and financial cost is higher.
(2) the tread form of wheel is optimized
The most widely used a kind of form of railway train wheel tread is wear pattern wheel tread, and this tread replaces the linear of taper tread wheel with circular arc.The two-point contact that wheel occurs through curve and track has been reduced or remitted in such design to a great extent, thus greatly slow down the side grinding of wheel, and worn profile tread is also conducive to reducing tread wearing and tearing simultaneously.The mode that tread optimizes anti-attrition proposes new requirement to the processing and manufacturing of wheel, and design cost is higher.
(3) strength of material of wheel is improved
According to the job requirement of wheel, require that wheel material has high strength and high-wearing feature on the one hand, also will have good break resistance and heat crack resistance on the other hand.Its main design thought is under the prerequisite ensureing that strength of material and hardness not too reduce, and improves the toughness of material.Design plan comprises reduction carbon content and mixes alloying element, and application low-carbon bainite wheel etc., improve the metallurgical quality of wheel steel simultaneously, ensure the due high purity of wheel steel, improvement Technology for Heating Processing etc. are highly beneficial to preventing high speed train wheel from damaging inefficacy.The mode improving material anti-attrition need find the optimal balance point between Material Strength and break resistance, and the Technology for Heating Processing of material is very complicated.
In sum, current various reduction train wheel noise and the method improving train wheel track resistance to abrasion and fatigue resistance have certain limitation, fundamentally cannot solve the noise reduction of train wheel and wearing and tearing and fatigue problem.The noise of train wheel has a strong impact on the daily life of railway surrounding resident, reduces its quality of life.The endurance failure of train wheel and attrition mass energy and cost manpower financial capacity.Therefore the noise and the skimming wear that reduce train wheel are the current task of top priority.Especially flourish in high speed railway cause, today that overall trip speed improves constantly, more need to possess that low noise, resistance to abrasion are good, the wheel of antifatigue, so need a kind of effective method badly to deal with this problem.
