实际载荷 meaning in English
actual load
Examples
- Actual loading testing
实际载荷试验 - It is generally very difficult to measure excitation in operating environment in the case of the complexity of the structure or the variant forms of the excitations , sometimes it is even immeasurable for the impact location is usually inaccessible
由于工程中结构的复杂性及激励形式的千差万别，工作状态下激励载荷常常难以测量，甚至因载荷作用点的不可达等原因而使实际载荷不可测量。 - By exciting at the other sites of the structure rather than the actual input points which are usually inaccessible , the modal parameters of the system and the dynamic loads are estimated through computations under both modal and physical coordinates . the errors of identification caused by the usual modification of the structure or boundary conditions are consequently evitable
以系统中的其他点作激励位置以代替常常为结构上不可达的实际载荷作用点，通过系统辨识得到系统的模态参数并在模态和物理两种坐标下对动态载荷作出估算，从而避免了通常需作的对系统结构的修改或改变边界条件而导致的识别误差。
