[0076] Example
[0077] Figure 7 shows a system for determining the test frequency in a wire vibration test of the present invention, the system includes: an excitation system composed of a signal generator (model: SG1020) and a power amplifier (model: D-300-3). The vibration energy signal generating device is used to generate a given excitation energy signal, and apply the excitation energy signal to the excitation point to vibrate the tested wire; the signal generator has a frequency input device for selecting an input frequency, so that the vibration of the tested wire is stabilized at a resonance frequency; the signal generator also has a frequency adjustment device to adjust the input frequency; as the vibration speed measurement device, there is an acceleration sensor (model: CA-YD-1073228 ), integrating amplifier (model: E5858T) and digital voltmeter (model: 2480R), the acceleration sensor is used to measure the instant value of the vibration acceleration of the excitat...
