Full-flow internal combustion engine oil filter test method
Part 7. Vibration Fatigue Test
1 Scope
This part of GB/T 8243 specifies a test method for determining the structural integrity of a full-flow oil filter against engine vibration. This test
The test method is applicable to spin-on filters with a maximum flow rate of less than 100 L/min and removable filters with a disposable filter cartridge.
This section applies to test pieces that are manufactured during the service period and the mechanical properties of the manufactured product materials do not change with temperature. For other types
The filter can also be used when the manufacturer of the filter manufacturer agrees with the buyer that it is applicable.

3.1 Terms and Definitions
The terms and definitions defined by ISO 4548-1 apply to this document.
3.2 Graphical symbols
The graphic symbols used in this section refer to the provisions of ISO 1219 [1].
4 Principle
Complete installation Oil filter assemblies that are subject to alternating forces due to vibration of the engine or mounting device, including filter seats, adapters, and safety
Mounting brackets and so on. This test method is used to verify the ability of the filter assembly to withstand vibrations for a predetermined number of cycles when under pressure.

The test rig should include the following components, as well as the necessary piping, fittings, and brackets (see Figure 1).
a) Electromechanical shakers, including the necessary hardware and electronic equipment for controlling and monitoring displacement, velocity and acceleration;
b) Oil pressure source, manual or mechanical control;
c) Oil pressure gauge, measuring range sufficient to cover the rated pressure of the test filter;
d) Two accelerometers, calibration linearity characteristics and range suitable for the test piece.
Explanation.

2 --- filter seat or joint; 6 --- test oil filter;
3 --- excitation axis; 7 --- shaking table platform.
4 --- pressure source;

6 test solution
The test solution should be a motor oil with a kinematic viscosity of less than 10 mm2/s ± 5 mm2/s at ambient temperature (viscosity class ISO at 63°C)
SAE5W at VG22 or 68°C) [2][3].
7 Vibration durability test
7.1 Mount the filter under test on the filter seat or fitting according to the recommended tightening torque or angle of rotation.
7.2 Mount the filter and the filter holder assembly on a rigid support or a non-deformable flat connector. Use suitable gaskets or seals.
Ensure that the mating surface does not leak.
7.3 Rigidly mount the bracket or plate adapter with the filter assembly on the shaker platform, ensuring that the filter's polar axis is perpendicular to the excitation axis (see Figure 1).
7.4 Connect the filter to the pressure gauge and a normal room temperature oil pressure source. Use a flexible tube to ensure that it does not interfere with the vibration filter device.
7.5 The input accelerometer is mounted on the filter seat/connector, the output accelerometer is mounted on the filter, and the output position of the accelerometer is output to
The approximate distance of the upper surface of the seal ring is 100 mm, and if the length of the filter is less than 120 mm, it is 0.85 times the length of the filter. Two plus
The polar axis of the speedometer should be parallel to the excitation axis (see Figure 1). Electrical connections between accelerometers, vibration control and monitoring equipment should be suitable.
7.6 Ensure that the test filter is filled with test fluid. All entrained air should be drained from the assembly. Pressurize the assembly to the rated pressure of the filter
Force, or manufacturer negotiates value with customers. If no test pressure is given, the test filter is pressurized to 500 kPa. During the entire test
Should maintain this pressure.
7.7 start shaker, such as filter manufacturers and customers no special negotiated value, then with a constant input acceleration peak 60m/s2 ± 0.3m/s2
Sweep the resonant frequency to 400Hz.
Determine the frequency of fatigue tests in 7.8 as described below. If resonance occurs at a single frequency, test at that frequency; if
If there is more than one vibration frequency, the test is performed at the maximum amplitude (peak to peak displacement); if no resonance occurs, then 150 Hz is used.
The frequency is tested.
Adjust the power of the shaker so that the input acceleration peak agreed with the filter manufacturer and the engine manufacturer is reached, or agreed upon by default
In the case of a value, the total vibration amplitude is determined at an acceleration of 60 m/s2.
Note. The total vibration amplitude (peak to peak) S, in meters (m), can be calculated according to equation (1).
S=
2π2f2
(1)
In the formula.
a---acceleration peak, in meters per second squared (m/s2);
f---Vibration frequency in Hertz (Hz).
7.8 The number of test cycles of the assembly is 107 unless there is a failure. Start the test at the frequency determined by 7.7. During the entire test process
The resonance frequency of the mid-test assembly may change, and the test filter resonance frequency should be verified periodically. Resonance tracking can be used
The vibration controller performs automatic control. Otherwise, repeat the process described in 7.7 and correct the frequency value after every 5 x 105 cycles of the test, and continue
Continue to test.
7.9 If there are no obvious failures after completing 107 cycles, the process of 7.1~7.8 is repeated, but the test filter is installed with polar axis and
The excitation axis is consistent. The location of the accelerometer is shown in Figure 2.
7.10 If there is no apparent failure in the 107 cycles tested in the second direction, determine the disassembly torque or rotation angle of the test filter
And compare it with the original settings.
7.11 Exhaust the test fluid in the test filter and carefully disassemble the filter to show any visible internal damage.
