The shock test bench sweep frequency test, also known as the vibration frequency response test, is a test method used to detect the working state of the impact table. Brilliance Heyi (Lianyungang) Equipment Technology Co., Ltd. said that the test can determine the working performance and vibration transmission characteristics of the impact test bench at different frequencies, so as to provide a basis for further improving the working performance of the test bench.
Specifically, the steps of the sweep test of the impact test bench are as follows:
1. Fix the test bench on the ground to ensure that the test bench will not move or tilt. At the same time, the test sample is installed on the test bench and positioned and clamped according to the test requirements.
2. Then, connect the test bench and the vibration source, adjust the frequency, amplitude and phase of the vibration source and other parameters to ensure that the vibration source of the test bench can vibrate according to the predetermined requirements.
3. Start the frequency sweep test, during the test, the vibration source will be scanned according to the preset frequency range, and the vibration response of the test bench at each frequency will be recorded at the same time. Typically, the test data is presented in the form of a frequency-amplitude response curve that reflects the vibration transmission characteristics and operating performance of the test bench at different frequencies.
4. According to the test results, analyze the working state and vibration transmission characteristics of the test bench, further optimize the structure and parameters of the test bench, and improve the working performance and accuracy of the test bench.
The swept frequency test of the impact test bench is widely used in aerospace, electronics, automotive, machinery and other fields to test the reliability and durability of various equipment and materials in the vibration environment.
