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 Terms, definitions and graphic symbols
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.
5 Test bench
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.

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). Elect...
