It is using transmission case as synchronization object above when the speed changer hangs up reverse gear（Order is 1）Each tooth calculated
The order data of the rotating parts such as wheel.
Next, complete vehicle weight, the resistance to sliding under different speeds, each notch speed of speed changer are set in pedestal control system
Than etc. control parameter, and data collecting system need gather rotating speed, throttle, moment of torsion, gear and order collection etc. collection
Parameter.Wherein when being configured to order collection, because above when being modeled and calculating to order, setting differential carrier
To synchronize object, and the order for defining differential carrier is 1, therefore it is that order collection is synchronous that we, which need to set differential carrier, herein
Change object, so we while speed changer vibration signal is gathered, it is necessary to set the rotating speed of synchronous acquisition differential carrier.
Second step, pedestal control system control engine start, controls load motor and shift actuator to be in standby shape
State, data collecting system start to gather each supplemental characteristic.
3rd step, pedestal control system send shift command, and speed changer is placed in into reverse gear by shift actuator, now sent out
Motivation and load motor are in idle running.
4th step, pedestal control system control engine and load motor realize that speed changer shake operating mode reproduces, this implementation
It is 13% that engine throttle opening is controlled in example, and control load motor simulation loading vehicle is travelled on 9% ramp with 9km/h speed
Resistance so that speed changer produce shake.
5th step, data collecting system are given the feedback of the information such as the rotating speed from speed changer, moment of torsion, gear, order are gathered
Fault analysis instrument, order data spectral line is calculated according to above-mentioned parameter information in fault analysis instrument, by it with being counted in the first step
Obtained order data are analyzed as follows：
According to the structure of the speed changer, it may be determined that power transmission line is during reverse gear：Input shaft → reverse driving gear →
Reverse idler gear → reverse gear driven gear → output shaft → main reduction gear → master subtracts gear wheel → differential carrier, dynamic because more than
All parts in power transfer route have the transmission of moment of torsion, and their order amplitude is larger under normal circumstances, and other do not have
There are the parts in power transmission line because being to dally or do not turn, without moment of torsion transmission, so order amplitude in theory
It is smaller.
By analyzing the order data spectral line for checking that fault analysis instrument obtains, it is found that following order amplitude is larger, be respectively：
1、4.29、5.46、7.10、13.87、73、180.35.By being contrasted with the order data being calculated in the first step, hair
Existing 7.10 ranks are two grades of driven gear orders, and idle running is should be in normal operation, does not transmit moment of torsion, so order amplitude should
It is smaller, and now there is the larger situation of order amplitude, illustrate that the transmission of moment of torsion occurs in intermediate gear, it is turned round with reverse gear transmission
Square acts on, and jitter problem occurs so as to result in speed changer.
Similarly, there is the analysis method of jitter problem and the above method one in speed changer when the speed changer hangs up other gears
Cause, be required for pre-establishing the order model of corresponding gear, calculate the order of each revolving part of speed changer when hanging up corresponding gear
Data.Speed changer shake operating mode reproduces when then realizing corresponding gear by said apparatus, by gathering each of now speed changer
Parameter signal, obtained order data spectral line is analyzed, i.e., the parts on power transmission line have moment of torsion transmission, rank
Secondary amplitude is larger, without the parts on power transmission line because being idle running or not turning should there is no a moment of torsion transmission, and if
The parts order amplitude occurred not on power transmission line is larger, then can determine that the parts to cause speed changer to be trembled
The reason for dynamic problem.
