Fixed frequency test: A sinusoidal vibration test is performed at a selected frequency (which can be a resonant frequency, a specific frequency, or a dangerous frequency) at a specified value and for a specified period of time. |
|
|
Sweep frequency test: Within the specified frequency range, the frequency is swept from low frequency to high frequency and then from high frequency to low frequency at a certain scanning rate according to the specified value until the specified total number or time is reached. |
||
|
Frequency octave test: The frequency sweep should be continuous and its frequency should change exponentially with time. The sweep rate (the rate of change of the controllable variable frequency over time during the sweep process df/dt) should be one octave per minute. The test time (acceleration time) for the frequency range to sweep from f1→f2→f1 once is calculated by the formula: 6.644log10 (high frequency/low frequency), and the sweep rate meets the requirement of 1 octave/minute. |
||
|
Logarithmic test: In logarithmic mode, the low frequency scanning speed is slow, and the high frequency scanning speed is fast. The logarithmic sweep is in units of 1 minute, and the sweep rate is doubled in 1 minute. |
||
|
Random test: Random vibration is a non-deterministic vibration. When an object vibrates randomly, we cannot determine in advance the instantaneous value of the motion parameter of a certain monitoring point on the object at a certain moment in the future. |
||
|
Program test: According to the test requirements, different test frequencies and times can be set, and single or multiple groups can be used. |
