中文摘要:
      目的 通过对某型号伺服排油管动力学特性研究,为管路设计方案的确定提供依据。方法 对三种设计方案的伺服排油管进行振动试验,测量其关键位置的应变响应,并结合有限元计算进行结果分析。结果 该伺服排油管的谐振频率在180 Hz附近,当振动环境在180 Hz附近有峰值时,会发生耦合共振,管路应变很大。结论 管路设计时谐振频率应避开环境的危险频率,无法避开时需要对管路进行加强。
英文摘要:
      Objective To provide a basis for the determination of pipeline design scheme by studying the dynamic character-istics of a certain type of servo oil drain pipe. Methods Vibration tests of three design schemes of servo oil drainage pipes were carried out to measure the strain response at key positions. The results were analyzed by the finite element method. Results The resonance frequency of the servo exhaust pipe was near 180 Hz. When there was a peak value near 180 Hz, the coupling resonance would occur and the strain of the pipeline was very large. Conclusion In pipeline design, the resonance frequency should avoid the dangerous frequency of environment, and the pipeline should be strengthened when it can not be avoided.
