Different fixtures fixed on electromagnetic shaker test products will have an impact on the test effect. In the shaking table test, the fixture is the key component to fix the product under test, and its design, manufacture and selection are directly related to the accuracy and reliability of the test results.
The influence of different fixtures on the test effect is mainly manifested in the following aspects:
1. The stiffness and quality of the fixture.
The stiffness and quality of the fixture are important factors that affect the test effect. If the rigidity of the fixture is insufficient or the mass is too large, it will cause the shaker performance to deteriorate and distort the test results. Therefore, when selecting fixtures, their stiffness and quality should be considered to ensure that they match the quality and stiffness of the product being tested to improve the accuracy of the test results.
Second, the fixing method of the fixture.
The way the fixtures are held can also have an impact on the test results. In a shaker test, the fixture needs to be firmly fixed to the product under test to avoid relative displacement or loosening of the product under test and the fixture. If the fixture is not firmly fixed, it will lead to inaccurate test results and even safety accidents. Therefore, when selecting a fixture, consider how it is fixed to ensure that it can be securely fixed to the product under test.
Third, the installation position of the fixture.
The location of the fixtures can also have an impact on the test results. In the shaker test, the gripper should be installed as close to the center of gravity of the product under test as possible to reduce the influence of the dynamic effect of the shaker on the test results. At the same time, the installation position of the fixture should also consider the shape and size of the product to be tested to ensure that the fixture can be firmly fixed to the product under test. Therefore, when selecting a fixture, consider where it will be installed to ensure that it can meet the test requirements.
Fourth, the material and processing accuracy of the fixture.
The material and machining accuracy of the fixture will also have an impact on the test results. If the material or machining accuracy of the fixture does not meet the requirements, it will lead to too large a gap or poor contact between the product to be tested and the fixture, which will affect the accuracy of the test results. Therefore, when selecting fixtures, their materials and machining accuracy should be considered to ensure that they can meet the test requirements.
To sum up, the fixation of different fixtures of electromagnetic shaker test products will have an impact on the test effect. Therefore, when selecting and using fixtures, factors such as its stiffness and quality, fixing method, installation position, material and machining accuracy should be fully considered to ensure the accuracy and reliability of the test results. At the same time, according to the specific test requirements and the characteristics of the product to be tested, the appropriate fixture should be selected to improve the test efficiency and quality.
