GB/T 14654--93
The test of shock absorber is mainly torsional vibration test, and the shock absorber is tested in the mechanical system. 6.1 Test instrument
Torsional vibration test instrument that meets the requirements of relevant industry standards is used. 6.2 Vibration test
Torsional vibration test is carried out within the specified engine speed range. 6.3 Test content
6.3.1Measure the amplitude of the internal components of the shock absorber and the vibration speed of the mechanical system. 6.3.2 Based on the test results, determine the natural frequency of the mechanical system, the torque characteristic parameters of the shock absorber, such as the torque characteristic parameters of the shock absorber. 6.3.3 Draw the speed-vibration curve of the shock absorber, and determine whether the rotational inertia and rotational speed of the shock absorber meet the torsional vibration performance requirements of the system based on the curve, and whether the shock absorber needs to be adjusted. 6.4 Damping adjustment
The damping adjustment of the shock absorber is carried out by changing the damping precision or the damping ring position. After adjusting the damping, the test is carried out according to the requirements.
7 Inspection rules
The inspection is divided into factory inspection and type inspection. 7.1 Factory inspection
7.1.1 The key shaft of the shock absorber must be subjected to magnetic flaw detection according to CB 819. Cracks are not allowed. 7.1.2 Check whether the depth of the shock absorber damping groove meets the design requirements. 7.1.3 Use a micrometer to check whether the radial runout of the external components of the shock absorber meets the requirements specified in the technical delivery documents. 7.1.4 Check whether the bleed holes on the oil inlet holes and the bleed screws are unobstructed. 7.1.5 For B shock absorbers, check whether the radial runout of the shaft is consistent with the requirements of the drawings or technical documents. 7.1.6 Products can only be shipped to the factory after they have passed the inspection of the quality inspection department and are accompanied by a product certificate. 7.2 Special inspection
For the first product or when there are major changes in the structure, materials, and process of the product that may affect the product performance, a type inspection should be carried out. 7.2.1 In addition to the factory inspection items, a torsional vibration test of the matching machine should also be carried out. 7.2.2 Sample and batch rules
If the number of full shock absorbers is less than 10), one unit shall be selected, if it is 15), two units shall be selected, and if it is more than 50, one unit shall be selected; the first inspection shall be doubled, and if it fails again, all units shall be returned. 8.1 Marking, packaging, transportation and storage
