请高手们指点指点下面这个图该怎么设置试验条件如下,
A.4 TEST PROCEDURES
A.4.1 Inspect test item to establish pretest criteria and physical condition. Record the results.
A.4.2 Verify the test items' functionality.
A.4.3 Perform low level sweeps of 10 Hz to 2000 Hz to identify any component resonant frequency. Record any such
frequency.
A.4.4 Expose the test item on the vibration equipment in accordance with the vibration profile for the determined
category. (See Figure A1.)
A.4.5 During testing the test item shall be operated and monitored as if it were in normal usage.
A.4.6 After completion of the test duration, inspect the test item and compare it to the pretest data and physical
condition. Record the results.
A.4.7 Repeat low level sweeps and note any significant changes in the resonant frequencies. A change in resonant
frequency may constitute a failure.
A.4.8 Repeat Steps A.4.2, A.4.3, A.4.4, A.4.5, A.4.6, and A.4.7 for each axis.
