In the present embodiment, car load road shaking table is by computer for controlling sends drive singal (input as simulation system), after D/A converter, electric-control system, servo-hydraulic device, tested vehicle, data collector etc., last again using vehicle spindle nose is measured obtain acceleration response and structural member on the strain-responsive that obtains send computing machine back to through A/D converter digitizing (output as simulation system), these links above together constitute a complete Road-Simulating Testing System.And in its Experiment Road spectrum storehouse for drive shaking table road spectrum signal different with leading to the specified link testing field road spectrum signal that adopts, wherein the ratio on smooth road, slope road and road of jolting is 4: 3: 3, by being captured in the data analysis in links according to such allocation proportion.The data of shop experiment and actual tests can be made to be close.
In the present embodiment: can be applicable to utilize road simulator stand to carry out the motorcycle stand fail-test implementation specification of motorcycle, trail bike and all-terrain vehicle (ATV) stand vibration reliability test according to the establishment of this test method, and test condition, method step and evaluation method that regulation utilizes road simulator stand to carry out motorcycle stand vibration reliability to be tested.
Because of road simulator stand impossible direct modeling road surface unevenness, the mainly response quautity of simulated motorcycle spindle nose place acceleration, its realization forms by by following 6 steps usually:
(1) gather and record the original response signal of vehicle when selected typical road travels.
Response signal can be acceleration, stress or displacement, and the response signal time history of testing field or user's road carries out record by analog quantity or the mode of digital quantity.In general, the number of sensors for data acquisition will more than the quantity of control channel during simulation laboratory test.
(2) carry out analyzing to original response signal and edit the Expected Response signal obtained required for laboratory road simulation test.
For the original signal collected, due to the existence of external interference signal, the zero drift deviation etc. of instrument existence itself, original signal itself is made to there is spectral artifacts.A prior factor is simultaneously, under the test condition of setting, respective specified is had to speed during test, road conditions, and the traveling of motorcycle always also exists the processes such as acceleration, deceleration, starting, the signal gathered in this time, though belong to random signal, is not that we want the actual test signal of analyzing and processing yet, therefore be necessary these signals do not belonged in setting test specification to be weeded out, and then carry out the analysis such as time domain, frequency domain.
The packet gathered due to test process Instrumental contains the signal under the operating mode such as acceleration, deceleration, parking, turning, brake of motorcycle, these are all the required operating modes under regular road surface, standard speed, therefore, required data be split from original floor data.No matter be strain or vibration signal, all just can to carry out adding up after a series of segmentation, merging, zero homogenizing process and abnormal some Processing for removing, the process of various correlation parameters in the rain-flow counting of fatigue load, time domain and frequency domain.
When motorcycle normally travels on road surface in addition, the size of the impact that tire is subject to and vibration is a stochastic process.Even if this is because on same road surface, travel fast identical, weather conditions are also identical, and by same driver-operated situation, the signal obtained also can not be completely the same, but its distribution meets the rule of stochastic distribution completely.Based on this reason, when the response signal measured by process, can process by the random signal regularity of distribution, and the distribution of Whole Response signal can not be affected.
(3) frequency response function of measuring test-bed
Use white noise signal as testing table drive singal and the response signal of measuring vehicle on simulator stand, utilize response signal to calculate the frequency response function of testing table.
(4) initial driving signal is estimated
According to Expected Response signal required in the frequency response function obtained in (3) and (2), calculate initial driving signal.
(5) iteration is performed
Because TT&C system (comprising sectional fixture, hydraulic system and test specimen) is nonlinear, inevitably there is cross-couplings, iterative process is exactly that error between continuous duplicate measurements measured signal and Expected Response signal is to revise the process of drive singal, final result is exactly will find the drive singal that can obtain Expected Response signal by iteration, and controls TT&C system with it.Meet the drive singal of precision, first must be RPC point (the acceleration signal measurement point namely on spindle nose) acceleration root-mean-square value error lower than 5%, secondly also to meet the response of non-RPC point in actual road test and bench test basically identical.
(6) fail-test is carried out
To obtain after suitable drive singal namely after Experiment Road spectrum, they are driven test-bed as the input signal of controller, then carries out fail-test with reference to industries concerned, corporate specification establishment testing program.After having tested, adopt the theoretical equivalent relation determined between bench test and actual road test of equivalent damage.
Be not difficult to find from motorcycle Road Simulation Test principle and method, adopt MTS stand to carry out motorcycle fail-test and can not substitute road fail-test completely, state in two kinds of experimental enviroments residing for motorcycle and stressing conditions all also exist some differences, and this is also the common recognition of industry.The meaning of research motorcycle stand reliability method is the lab simulation realizing the test of motorcycle outdoor road, by comparative analysis and adjustment, reproduces the force-bearing situation of motorcycle main components, realizes the reproduction of waveform or power spectrum; And tested fast or strenuous test by certain mode, thus to obtain than actual road test more accurately, more, more scientific test findings realize by this improving product design fast, improve product independent development level, strengthen the object of competitiveness in the international market.
By a series of test findings, the method for load spectrum is utilized to be scientific and reasonable to complete motor drive axle fail-test.Through the comparative analysis to test figure, can show that some have the result of directive significance to product design and improvement, absolutely prove the motorcycle component Road Simulation Test method and technology practical based on loading spectrum, engineering significance is obvious.In actual applications can also according to research needs, adopt the test method strengthening frequency or load to carry out strengthening or overload test research, this is also that actual road test is incomparable.
