Description
Technical field
Patent of the present invention relates to a kind of train bogie high-frequency percussion testing table.
Background technology
Transportation by railroad is to the development of high-speed overload, make the vibration aggravation of train operation, the Service Environment of each parts worsens, and the structural strength problem that is exposed to bogie, wheel shaft and car body etc. increases gradually, particularly, after the desired structure lightweight of bullet train, structural strength problem will be more outstanding.
And after train running speed significantly improves, extraneous Forced Frequency sharply increases, make wheel occur that to, framework and car body frequency exceedes respectively 500Hz, 50Hz and 25Hz and above dither and impacts.It is one of current letter problem to be solved that dither impacts the safety in operation and the integrity problem that bring.When travelling speed exceedes after 300km/h, train sharply shortens as the time of track switch, low joint, intersection, track Short wave irregularity etc. by various outside excitations, cause train to produce violent dither, show as train one rail system wheel-rail interaction aggravation, all there is the fatigue break of flutter acceleration components in various degree etc. to High Rotation Speed stability decreases, framework high-frequency excitation unstability, car body whole and part in wheel, has a strong impact on train operational safety.High-frequency excitation has affected passenger's riding comfort.Human body bears the longest vibration frequency of time generally within the scope of 1-2Hz, and when vibration frequency exceedes after this scope, the ability that human body bears dither will decrease, and can reach at short notice fatigue state, have a strong impact on train riding comfort.Dither impacts and has accelerated vehicle one rail system parts hurt.In the bullet train Parts life-span relevant with structural strength, the frequency is higher, and parts hurt is faster, occurs that the possibility that structural fatigue crackle even ruptures is larger, and safe length of service also shortens thereupon, has increased application and maintenance cost.Impact the impact for bogie and parts thereof in order to study dither, set up bogie high-frequency percussion testing table and be very important.
Existing high-frequency percussion test is all made device at intensity test bench by hydraulic pressure and is implemented.Test only can be carried out impulse test to the rigid element of bogie, and can not carry out high-frequency percussion test to complete bogie entirety.And frequency is because the operation valve of hydraulic actuator and flow of pressurized quantitative limitation can not complete the test of ultrahigh frequency.Therefore.The high-frequency percussion testing table existing at present cannot complete the high-frequency percussion test of whole bogie, and is subject to the impact of various hardware facilities.
Summary of the invention
The object of patent of the present invention is to provide a kind of train bogie high-frequency percussion testing table, and this testing table can complete the high-frequency percussion test of a bogie, and experimentation cost is low, and test efficiency is high, and test findings is more true and reliable; Can test the concrete response parameter of the suspension on bogie simultaneously; And very little to surrounding environment influence when test.
The present invention realizes the technical scheme that its goal of the invention adopts, a kind of train bogie high-frequency percussion testing table, the steamboat that comprises train bogie (1), bogie (1) the bottom High Rotation Speed of testing use is fixed in the pit of spill ground (4) to bearing (3) by wheel to (2) to (2), steamboat, steamboat is connected with gear case (5) to the one end of (2), and the other end of gear case (5) is connected with motor (6).It is characterized in that: the steamboat of described High Rotation Speed is all installed in the pit of spill ground (4) bearing (3), gear case (5) and motor (6) (2), wheel, described bogie (1) and be placed on steamboat to (2) and spill ground (4) top.
The course of work of the present invention and principle are:
By wheel of bogie, to being placed on steamboat to upper, another wheel is to being fixed on the upper surface of spill ground.Starter motor, motor is connected with the input shaft of gear case by shaft coupling, thus the gear of drive gear casing rotates, and the output shaft of gear case drives steamboat to rotating, and steamboat is to driving a wheel of bogie to rotating again.Thereby carry out the suspension parameter test of bogie, vibration acceleration test, displacement measurement, strain testing etc.
Beneficial effect:
One,, on a testing table, completed the high-frequency percussion test of whole bogie.Than single truck components high-frequency percussion test, experimentation cost is low, tests more conveniently, and test efficiency is high.And more approaching with true train ruuning situation.The test figure obtaining is truer, for design and the maintenance of train provide test figure more reliably.
Two, this testing table completes high-frequency percussion test by the mode of Electrified Transmission machinery, can save greatly experimentation cost.Can simulate more really train operation stressing conditions, also make test figure more true, reliable.
Three, this testing table by spill ground by steamboat to, wheel bearing, gear case and motor are all included in pit, the security while having protected High Rotation Speed is played flat every the effect of making an uproar simultaneously.Thereby ensure that test site buildings and resident living environment is around unaffected; Meanwhile, pilot region is not protected and is affected by external environment too, makes test figure more genuine and believable.
Four,, while test, use real bogie and a complete set of resilient suspension system.And be no longer subject to the restriction of various hardware and software, more approaching with train truth, test findings is more true, reliable.
Above-mentioned steamboat to the concrete formation of (2) is: axle (2a) is fixedly connected with two wheels (2b), has uniform projection (2c) or pit (2c) on the surface of two wheels (2b).。
Such steamboat, to can facilitating again accurately the situations such as uneven, wheel flat, out-of-roundness, scratch and abnormal wear on Reality simulation circuit reliably, facilitates processing and fabricating simultaneously.
Above-mentioned wheel to the concrete structure of bearing (3) is: by two wheels, bearing (3) is fixed on steamboat in the pit of spill ground (4) to (2), wheel couples together by rolling bearing (3a) and the axle (2a) of steamboat to (2) to bearing (3), and two wheels are positioned at the outside of steamboat to (2) upper two wheels (2b) to bearing (3).
Such wheel can support steamboat to mating different bogies easily to bearing, simultaneously for convenience detach.
The concrete structure of above-mentioned gear case (5) is: gear case (5) has an output shaft (5a) and an input shaft (5b), axle (2a) one end to (2) is fixed and is connected output shaft (5a) with steamboat, and input shaft (5b) is connected by shaft coupling (7) with motor (6).
Such gear case is conveniently transferred to steamboat to coming up by motor output speed.Do not need other transmission converting system, get excited rapider.
The concrete structure of above-mentioned train bogie (1) is: a wheel of bogie (1) is to being placed on steamboat to (2) top, and another wheel is to being fixed on the upper surface of spill ground (4).
Such bogie fixed form is identical with the way of restraint of real circuit train operating mode, has ensured to test authenticity stressed and constraint.
