It is bolted with experimental box body 40；Entire experimental box body 40 is bolted on cabinet chassis 53；
As shown in Figure 1, experiment 11 rear end of oil pocket is provided with cavity oil liquid temperature sensor mounting hole 52；
It is two current vortex positions respectively as shown in figure 3, processing three row's sensor mounting hole side by side in 15 left-hand face of cylinder body
Displacement sensor mounting hole 60, three armoured thermocouple mounting holes 61, three piezoelectric pressure indicator mounting holes 62, sensing of the same race
Device mounting hole is distributed along the axial cylinder, and away from being 15mm, circumferentially spaced apart 45 ° of sensor not of the same race are distributed at center；
It is that two current vortex displacements pass respectively as shown in figure 4, processing three row's sensor location holes side by side on 14 surface of bushing

Body it is self-locking, it is ensured that the rotation around axis does not occur for cylinder body 15 in a test process, avoid to test result generate
It influences.
Oil film layer thickness variation between bushing 14 and test plunger 13 is very fast, and oil film pressure is high, and working environment compares evil
It is bad, therefore electric vortex method is selected to carry out oil film thickness measurement；Eddy current displacement sensor 44 is flushly mounted with 14 inner wall of bushing；It surveys
Examination plunger 13 is cylindrical, and can determine a circle according to two o'clock and radius, if therefore when cylinder body 15 can not rotate, at least
Four displacement sensors are needed, the offset of two plane inner plungers of axis direction is measured, to calculate plunger gradient, are obtained
The distribution of oil film thickness out；And the technical program uses and can be rotated cylinder body 15, it only need to be in the electric whirlpools of axis direction arrangement two
Flow displacement sensor 44, by measuring twice, the two groups of Data Synthesis measured when cylinder body 15 is in different angle, to obtain
Effect as the test of aforementioned four sensor；In the case that cylinder body can not rotate, two fixed circumferential angles can only be surveyed
The data of four positions, the technical program rotate cylinder body 15 by 18 worm screw 19 of worm gear, and multiple measurement data is synthesized,
Allow eddy current displacement sensor 44 to measure circumferential oil film thickness at any angle, the use of mathematical measure reduced with this,
Keep the measurement result of circumferential oil film pattern more intuitive, is more in line with actual conditions；And there is still a need for pass through mathematics for oil film axial direction
Means calculate, to obtain the pattern of entire oil film；The quantity of eddy current displacement sensor can also be increased in the axial direction,
The measurement of nonlinear data is carried out, to keep the oil film thickness data obtained more accurate.
The measurement of oil film temperature considers to use armored thermocouple, the armour using contactless measurement, on bushing 14
Dress thermocouple location hole 64 is not punched；14 inner surface of bushing is directly contacted with oil film when test, when oil film temperature reaches one
After balance, as the distribution of oil lamella Temperature Distribution and 14 inner wall temperature of bushing is, due to the transmitting of the temperature in metal parts
It need to only consider heat transfer, analysis gets up to be easier, so according to the temperature of measurement point measured in bushing 14, material itself
Thermophysical property and temperature transfer mode, counter can push away the Temperature Distribution of oil lamella.
Due to test plunger 13 and bushing 14 between oil film pressure change constantly, when 1 velocity of rotation of wobbler shaft compared with
Gao Shi, Pressure change frequencies are also higher, so selection piezoelectric pressure indicator measures；It is pressed according to the survey of sensor former
Reason, is only just capable of measuring required data when the oil liquid pressure of oil film is applied on pressure sensor, so each survey is pressed
The center for putting piezoelectric pressure indicator location hole 65 on i.e. bushing 14 is all machined with pressure sensor and draws oilhole 66, so as to pressure
Oil can be applied on sensor.
When test, stepper motor 21 is self-locking, in addition self-locking and the first cylinder body spring bearing 17 of 18 worm screw 19 of worm gear, second
The fixation of cylinder body spring bearing 28, so that 15 circumferential and axial of cylinder body can not all move；External oil feed line to test plunger 13
Pressure oil is provided in the plunger cavity of kicker ram 49, test plunger piston slippery boots 12 and kicker ram piston shoes 51 are pressed in swash plate face
On, it is formed simultaneously static pressure support；Hydraulic motor 59 drives wobbler shaft 1 to rotate, and the rotation in swash plate face is so that test plunger 13 and auxiliary
It helps plunger 49 to move back and forth, simulates and really pump oil suction oil extraction, after balance to be achieved, the data such as record temperature, pressure, displacement；Stop
Only hydraulic motor 59 start stepper motor 21, cylinder body 15 are made to turn an angle after whole system shuts down, and stop step
Into motor 21 and self-locking, it is again started up hydraulic motor 59, re-starts above-mentioned test；Repeatedly, record multiple groups cylinder body 15 exists
The data of oil film characteristic under different angle, and synthesized, finally obtain the characteristic of entire plunger cavity oil film.
