ASTM D999-08 Standard Test Methods for Vibration Testing of Shipping Containers
Method B—Single Container Resonance Test.
Method C—Palletized Load, Unitized Load, or Vertical Stack Resonance Test.(这个标题的正解翻译,哪位大侠能告知?)
Suitable fixtures and attachment points shall be provided to rigidly attach the test container to the platform for Method B.
Restraints shall be provided to restrain the horizontal motion of the test specimens on the platform without restricting the vertical motion of the specimen(s), for Method C.
根据这两段话的描述,我是否可以认为B方法的样品需要固定装夹,而C方法的样品不需要固定装夹。
那么B方法需要做三个方向的振动,而C方法只需要做垂直方向的振动?不知道是否是这个意思呢?
