航天器力學(xué)試驗回顧、啟發(fā)與展望

A historical review of mechanical tests for spacecraft

  • 摘要: 中國航天器的研制與火箭的發(fā)展密切相關(guān)，航天器力學(xué)試驗也是借鑒了火箭研制中力學(xué)試驗的經(jīng)驗。振動試驗至今仍沿用了x、y、z 3個方向分別進(jìn)行振動試驗的方法；1997年ESTEC建立了HYDRA 6自由度振動試驗系統(tǒng)，開始了以x向為主的6自由度振動試驗的新方法，這對我國航天器振動試驗技術(shù)是一個重要的啟迪。

     

    Abstract: The development of spacecraft is closely related to the development of rocket in China. The experience of mechanical tests for rocket is much adopted in the spacecraft development. Vibration tests are conducted in x, y, z directions independently. Since HYDRA vibration system was built by ESTEC with six degrees of freedom in 1997, some new vibration test methods have been applied, which will promote tests for spacecraft.
