Foreword

This standard replaces GB/T 10431-1989 "Transverse vibration testing method for fasteners." This standard compared with GB/T 10431-1989 main changes are as follows. --- Change the test curve example; --- Increase the data analysis and the results of its judgment (see 7.2); --- Cancellation Appendix C. The Standard Appendix A and Appendix B are informative. The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee fasteners (SAC/TC85) centralized. This standard is drafted by. Productivity Promotion Center in the machine. This standard replaces the standards previously issued as follows. --- GB/T 10431-1989. Transverse vibration testing method for fasteners

1 Scope

This standard specifies the lateral vibration testing and data processing methods for the determination of the fastener locking properties. The resulting test according to this standard As a result only under certain conditions than the evaluation basis, there is no absolute quantitative indicators.

2 test principle

Test on the fastener lateral vibration test machine. Tighten the fastener to be tested in the test apparatus so that a certain clamping force. By means of alternating lateral displacement in the testing machine is clamped between two metal plates to produce, so that a loose connection, resulting in the clamping force is reduced or even completely lose Loss. Continuous recording of the instantaneous value of the clamping force, based on the analysis of the recorded data can match the performance of locking fasteners determined. During the test, Clamping force decreases slower, locking the better the performance; the other hand, the clamping force decreases faster, locking the worse performance.

3 test equipment and instruments

Constituting 3.1 A block diagram of the test apparatus and the apparatus shown in Figure 1. A block diagram of FIG. 1 testing facility 3.2 vibration test machine As used in this test vibration test machine should be able to meet the test requirements of the frequency and amplitude of the test, the lateral vibration waveform should be sinusoidal. 3.3 precision equipment 3.3.1 clamping force measurement error should be within ± 3%. 3.3.2 The lateral displacement measurement error should be within ± 1%.

4 Test conditions

To make the results comparable, you should choose the same test conditions. 4.1 Environmental conditions The test shall be carried out at ambient temperature and pressure, clean environment. 4.2 Lubrication When the specimen clamping, thread and should be added to the lubricant in the bearing surface to avoid scratches threads and bearing surfaces or heat generated by friction killed Phenomenon, affecting the accuracy of test results. Test frequency and amplitude 4.3 free state The frequency of testing according to the actual frequency of use or testing requirements to determine, if not determined, recommended 12.5Hz; free state (clamping force Amplitude zero) under the bolt should ensure that the specimen is not cut. 4.4 Pre-test clamping force Pre-test clamping force according to test requirements or specimen clamping force is determined. 4.5 Number of test pieces The number of specimens in each group is determined according to test requirements. In general, it is recommended to take 10 each, if you find the vibration characteristics, security in the test There are large differences when loading or removing torque, etc., should be supplemented with 15. ......
