求翻译：当所受动载荷的频率与壳体结构的某一固有频率接近时，可能引起结构共振，从而产生很高的动应力，造成强度破坏或产生不允许的大变形，严重影响了行车安全性。是什么意思？

Suffered the frequency of dynamic load and a natural frequency of the shell structure close to, may cause structural resonance, resulting in a high dynamic stress, resulting in strength failure or large deformation are not allowed, a serious impact on traffic safety.

When passive load frequency and shell structure some natural frequency close, possibly causes structure resonating, thus has the very high dynamic-load stress, creates big distortion which the intensity destroys or produces does not permit, has affected the driving security seriously.

When the frequency of dynamic load and at a natural frequency close to the structure of the shell, there may be a resonance structure, which results in very high dynamic stress, cause of strength failure or does not allow large deformations, seriously affect traffic safety.
