摘要
随机振动试验是工程中常用的一种模拟试验,应用时振动量级有可能超出振动台极限而造成破坏.列举出对随机振动试验有直接影响的几个振动台的关键指标,根据试验样品的振动条件,估算出随机振动试验所需的最大推力、最大位移和最大加速度.通过与振动台极限指标进行对比,考核该振动台能否进行该项试验.
The Random vibration experiment is a common simulation test in the engineering experiment, while applying the vibrate quantity class, it will probably outrun vibration set extreme limit and result in breakage. Through enumerating a few key index signs of vibration pedestal directly influencing the random vibration experiment, and according to the vibration condition of product, the full thrust, the largest displacement and the maximum acceleration required to random vibration experiment were estimated. By contrasting with the vibration set extreme limit index signs, the vibration set was tested to be capable of carrying on that experiment.
