性能要求主作动器的设计性能要求是根据非阻尼响应冲击谱的冲击值、使用多作动器的同步要求、产生两种波型的能力以及再现性要求来确定的。如图1所示,作动器应能提供范围较广的特有响应冲击谱,其公差应保持在每一能级的公差极限内。在0.1～1000赫的频率范围内有5个主要能级,第1能级是最低的,第5能级是最高的。此外,在1级以下还规定了3个次能级
Performance Requirements The design requirements of the main actuator are based on the impact values of the non-damped response shock spectrum, the synchronization requirements using multiple actuators, the ability to generate both waveforms, and the reproducibility requirements. As shown in Figure 1, the actuator should provide a wide range of unique response shock spectra, with tolerances within tolerance limits for each energy level. There are five main energy levels in the frequency range from 0.1 to 1000 Hz, with the first energy level being the lowest and the fifth energy level being the highest. In addition, below the level 1 also provides three sub-level
