非破坏试验的试验荷载为设计值的1 5倍时，节点安全可靠。

When the experimental load of the nondestructive test reaches 1.5 times of the designed value, the joint is safe and reliable.

由于这是一种非破坏试验方法，所以仅一个模型就可以对几种不同转速以及静过盈状态下的应力进行测定。

The test method employed is non-destructive, so that only one model is needed for investigating stresses in a rotating disc at various speeds, and for determining the static shrink fit stresses.

该试验装置可以更好地从均匀加载的角度研究非均匀，非连续介质的变形及破坏规律。

This testing machine is good at studying the deformation and failure of inhomogeneous and discontinuous media from the Angle of loading equability.
