Description
Technical field
The present invention relates to Transit Equipment testing field, is applied to Transit Equipment Big Gold more particularly, to one kind
The hot and vibration integrated aging treatment method of metal elements.
Background technology
With being continuously increased for train running speed and axis weight, Transit Equipment is also just towards systematization, integrated
Direction is developed, such as：The size of the core train apparatus such as traction convertor becomes increasing with quality, its main structure（Big Gold
Metal elements）Because the residual stress caused by process such as welding, cutting to its dimensional accuracy, load capacity during the manufacturing
Etc. great influence is caused, component can be caused to play pendulum, so as to reduce the dimensional stability and mechanical-physical of component
Performance.The harm of residual stress is very much, its yield limit to hardware, fatigue life, deformation, brittleness destruction etc. are made
Into tremendous influence, component can be caused to be deformed and fail during manufacture and use, while accelerate metal material and exist
Corrosion rate in corrosive environment.
To eliminate the residual stress of hardware, in the prior art generally use natrual ageing, heat aging and oscillating aging.
Heat aging is exactly that workpiece heat to bullet is moulded row transition temperature, and is kept for certain time, the residual stress of workpiece is relaxed,
Then temperature is extremely slowly decreased, workpiece is in low-stress state after cooling.Oscillating aging（Vibratory
Stress Relief）Processing is the external periodic force in vibrator（Exciting force）Under the action of, processed workpiece is produced altogether
Shake, and certain vibrational energy is delivered to all sites of workpiece by this resonance mode, inside workpiece occurs microcosmic
The lattice of plastic deformation-be warped gradually restore balance state.Dislocation slides again and pinning, so that inside workpiece
Residual stress is eliminated and is homogenized, and finally prevents workpiece from deforming and cracking during processing and use, ensures workpiece size
The stability of precision.Oscillating aging is to replace natrual ageing and heat aging using the method for vibration processing, its operation principle is logical
Crossing external drive makes component be in vibrational state, reaches by the vibration processing of certain time and eliminates residual stress and stable dimensions
Purpose.
At present, it is general only individually to use natrual ageing, heat aging and vibration when carrying out ageing treatment to hardware

Short, the advantages that effect is good, remarkable in economical benefits, it is widely used in machinery manufacturing industry.It is but large-scale for Transit Equipment
For hardware, since its structure size is big, sole mass is big, by conventional heat aging or vibration stress relief treatment method all
It is difficult to make the eradicating efficacy of residual stress to reach optimum state, and common heat aging is not suitable with greatly because of high cost and high pollution
The industrial production of batch is gradually eliminated.
Band large-scale metal component vibration stress relief treatment method and step commonly used in the prior art is generally：
（1）The supporting of component：The selection of supporting, rightly supporting workpiece can make workpiece steadily and vibrate freely, then will swash
Shake device and sensor using clamp on workpiece.
（2）Frequency sweep before component shakes：Make the rotating speed of the motor for vibration exciter uniform raising speed in appropriate scope, it is to find that it, which is acted on,
Component resonant frequency and corresponding amplitude.
（3）Determine resonant frequency：During above-mentioned frequency sweep, the frequency corresponding to working amplitude maximum is preferably common
Vibration frequency.
（4）Resonant frequency vibration：Component vibrates the regular hour under selected resonant frequency.
Existing vibration stress relief treatment method described above has following technological deficiency：
（1）The oscillating aging excitation set of application specific is needed, generally using motor as exciting bank；
（2）Using component resonant frequency point determined by open loop control mode, there are large error；
（3）Frequency vibration flowing mode is determined to large-scale component into row energization only with sine sweep and resonance point are sinusoidal, and some structures
Residual stress in part can not be eliminated by sinusoidal vibration, thus sometimes general vibration stress relief treatment method is not
Optimal effect can be reached.
