Electrodynamic Vibration Testing System Final Testing Report

This is an article about EV203H electrodynamic vibration testing system’s testing report. The ambient temperature tested by the machine is 26.5 degrees Celsius and the humidity condition is 50%. Electrodynamic vibration testing system model: EV203H0404-2, Equipment’s Serial Numaber: WEW-L1910146. Vibration test system performance testing according to JJG948 1998: Digital electrodynamic vibration testing system. The testing report would provide recommendations and suggestions for test specimen’s functions and potential risk to ensure the continued reliable operation and accurate results of new products under development.

The electrodynamic vibration testing system final testing report provides typically includes an overview of the testing process, which would indicate how the system is set up, the protocols and procedures used, and any notable challenges encountered during testing. Additionally, it would include detailed results and analysis of the vibration tests themselves, including the frequency and amplitude of the vibration and any discrepancies or anomalies observed during testing.

2.1 Max Random Performance Graph According to ISO 5344|Payload= 23 kg (finite loading 20Kg) f0= 1925 Hz, A= 10*100%=10 g rms Vmax=36.6v Imax=19.5A|The load mass is more than 3 times of the moving coil mass, and the vibration point falls within 2000Hz after loading. If the output is greater than 2000Hz, the output is 70% of the rated value.
