In the numerical experiment, the plate was subjected to five types of input forces, i.e., sinusoidal, triangular impulse, rectangular impulse, a series of impulses and random. 在数值模拟实验中,此矩形平板受到五种型式输入负荷的作用,亦即正弦力、三角形冲击力、矩形冲击力、连续冲击力及随机力等。
Under sinusoidal excitation, the feasibility of utilizing RLC circuit as the impulse power source is analyzed. 分析了正弦激励下的RLC电路作为脉冲功率电源的可能性。
Exponentially decayed sinusoidal function is suggested as a dictionary atom after having a good understanding of machinery impulse response waveforms. A method of adaptive signal representation with the atom is proposed based on the matching pursuit and the genetic algorithms. 分析了机械系统动态响应的波形特点,提出用指数衰减正弦波作为字典原子来分解信号,并结合匹配追踪和遗传算法给出了一种自适应信号分解方法。
