4.1 The ground instrument must be subjected to vibration tests in three axes. If the three-axis test conditions cannot be met due to temporary limitations of the perturbation equipment, the three-axis vibration test can be achieved by changing the position of the instrument for which the normal placement position of the instrument is allowed to be changed.
4.2 Downhole instruments are only tested in two axes.
4.3 The performance of the test equipment shall comply with the relevant provisions of GB2423.10. 5 Tests
, 1 Initial inspection
The test instrument shall be inspected for appearance, mechanical and electrical properties in accordance with the provisions of the product standards. Whether the test instrument needs pretreatment shall be specified in the relevant product standards. 5.2 Installation
The instrument should be fastened on the vibration table (the center of gravity of the instrument under test should be located in the center of the vibration table) in a position that simulates the normal working position of the instrument. The exciting force should be directly transmitted to the body of the instrument under test without passing through the vibration-damping feet, handles or other buffering devices. The devices (bolts, pressure strips, pressure plates, etc.) that fasten the instrument under test should avoid self-resonance during the vibration test. 5.3 Observation
In order to observe the resonant parts in the body and measure the vibration, holes can be opened on the shell or transparent plastic windows can be used. When the shell or cover must be removed to observe and measure the status of the internal components of the machine, it is allowed to remove the shell or cover. 5,4 Normal working confirmation
The vibration test in the working state should put the instrument under test in a way that can easily confirm its normal working, such as monitoring the output signal or data of the instrument.
5.5 Search
Sweep the frequency of the instrument under test according to the provisions of 4.1 and 4.2, and record the resonance point on each axis. The number of scans should be based on the principle of meeting the needs of recording.
'5.6 Resonance retention
5.6.1 For the resonance points of the test instrument in each axis, the resonance retention test shall be carried out according to the vibration acceleration and time specified in the table. When there are many resonance points, only four relatively hot vibration points shall be taken on each axis, and the resonance amplitude values ​​of the main components or parts shall be recorded. 5.6.2 When the instrument does not reach the resonance point within the specified frequency range, the vibration acceleration shall be increased by 4.9m/s\ at the upper limit frequency of the group to which it belongs, and the vibration shall be maintained for 10 minutes to observe the vibration state of the instrument. 5.7 Vibration cycle
The test instrument shall be subjected to vibration cycle test as specified in the table, and attention shall be paid to observe whether there are any abnormalities in the test instrument during the continuous cycle.
5.8 Repeated resonance search
Perform repeated resonance search on the instrument under test according to the provisions in the table, and observe the frequency, amplitude and resonance position of the resonance point. Compared with the records of the first resonance search, the resonance frequency, amplitude and resonance position should not have significant changes. 5.9 Intermediate test
If necessary, according to the relevant product standards, the instrument under test must be in working condition and perform performance tests during the entire process or certain stages of the conditional test.
6 Final test
Perform appearance inspection, mechanical and electrical tests on the instrument under test according to the requirements of the relevant product standards. The technical performance of the instrument under test should meet the requirements of the product standards.
