The dynamic loads must be extrapolated using aeroelatic scale factors . 动力载荷必须用气动弹性尺度因子来推算。
Dynamic loading is produced by seismic forces, non-steady wind, blast, reciprocating machinery . 动荷载是由于地震力、不稳定的风、冲击波,往复式机器所产生。
The dynamic loading resulting from blast, gusts of wind, or seismic forces is generally not harmonic . 由于冲击波,阵风或地震力所产生的动力荷载一般不是谐和的。
The increasing availability of high-speed digital computers has initiated a trend whereby earthquake loads are represented by dynamic loads . 高速数字电子计算机的效用日益增长,它开创了一种将地震荷载表示为动荷载的趋向。
