The indicators of the electromagnetic shaker simulation aircraft operation test mainly include the following aspects:
1.Frequency range: Electromagnetic shakers need to be able to operate within a certain frequency range. In general, this range should cover all frequencies that an aircraft may encounter while operating, including low and high frequencies. The wider the frequency range, the more comprehensive the simulation of the vibrations of the aircraft during operation.
2.Amplitude: Amplitude is the maximum amplitude of vibration produced by an electromagnetic shaker. When simulating aircraft operation tests, it is necessary to ensure that the shaker can work within a certain amplitude range to simulate the vibration of the aircraft under different operating conditions.
3.Dynamic Range: Dynamic range refers to the range between the maximum and minimum acceleration that an electromagnetic shaker is capable of withstanding. When simulating an aircraft operational test, it is important to ensure that the dynamic range of the shaker is large enough to cover all the accelerations that may be encountered while the aircraft is operating.
4.Stability: Stability refers to the ability of an electromagnetic shaker to maintain stable performance during long-term operation. When simulating aircraft operational testing, it is necessary to ensure that the shaker remains stable over long periods of operation to avoid affecting the test results.
5.Repeatability: Repeatability refers to the consistency of the results of an electromagnetic shaker when running the same test multiple times. When simulating aircraft operational testing, it is important to ensure that the repeatability of the shaker is high enough to avoid affecting the test results.
6.Environmental adaptability: Due to the complex and ever-changing environment in which aircraft operates, electromagnetic shakers need to be able to maintain stable performance in different environments. When simulating aircraft operational tests, it is necessary to ensure that the shaker can adapt to different environmental conditions to avoid affecting the test results.
7.Real-time control: Electromagnetic shakers need to have real-time control capabilities so that they can be dynamically adjusted to test needs during the test. When simulating aircraft operational testing, it is important to ensure that the shaker can be controlled in real-time for more accurate test results.
In short, the indicators of the electromagnetic shaker simulation aircraft operation test mainly include frequency range, amplitude, dynamic range, stability, repeatability, environmental adaptability and real-time control. Only when these indicators meet the requirements can a more accurate and comprehensive simulation of aircraft operation test be achieved.
