| 中文摘要: |
| 目的 细长体两点激振试验方案中，更好地选择激励位置、控制位置和悬挂点的位置。方法 制定两点激振试验方案时需要参考试件的模态信息。结果 根据试验方案的确定方法和模态试验理论，利用试件模型的模态试验结果，建立了一种试验方案制定时的激振位置、控制位置、悬挂位置计算方法，量化了试验方案的确定方法。结论 通过两种试验方案控制位置、悬挂位置计算数值的对比，可以直观地对比不同试验方案的优劣，有利于两点激振试验方案的制定和选择。 |

| 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. |
