| Abstract: |
| Objective To select proper position for excitation, control and suspension in slender dual-exciter vibration test. Methods The modal results can be referenced when designing the testing program before the dual-exciter vibration test. Results Based on the designing method of testing program and the modal test theory, the calculation formulas of excitation location, control location and hanging location were established when designing the testing program based on the modal test results. Conclusion Comparison of two test programs in numerical calculation of excitation, control and suspension position could compare advantages and disadvantages of two test programs and be favorable for making and selection of dual-exciter vibration test program. |
