Unless otherwise specified, this motion shall be applied for 2 hours in each of three mutually perpendicular directions (total of 6 hours). If applicable, this test shall be made under electrical load conditions.样品承受振幅为1.52mm(P-P) 的简谐振动,其频率在10 至55Hz 之间均匀变化,整个频率范围内(从10至55,再从55至10)约历时1分钟. 除非另有规定,在相互垂直的三个方法上各振动2小时(总共6 小时).如果适用,振动应在施加电负载的条件下进行4.1.5 Test condition II 98.1 m/s2 (10 gn) peak 测试条件【峰值：98.1ms2(10gn) 】The specimens, while deenergized or operating under the load conditions specified, shall be subjected to the vibration amplitude, frequency range, and duration specified , and and , respectively; see figures 2 and 3.在没有承受或承受规定电负载的情况下,样品应分别承受如、 及 所规定的振幅、频率和时间的振动，见图2和图 Amplitude 振幅The specimens shall be subjected to a simple harmonic motion having an amplitude of either 1.52 mm (0.06 in) double amplitude (maximum total excursion) or 98.1 m/s2 (10 gn) peak, whichever is less.

Sweep time and duration 扫描时间及持续时间The entire frequency range of 10 Hz to 500 Hz and return to 10 Hz shall be traversed in 15 minutes. This cycle shall be performed 12 times in each of three mutually perpendicular directions (total of 36 times), so that the motion shall be applied for a total period of approximately 9 hours. Interruptions are permitted provided the requirements for rate of change and test duration are met. Completion of cycling within any separate band is permissible before going to the next band. When the procedure (see 4.1.4) is used for the 10 Hz to 55 Hz band, the duration of this portion shall be same as the duration for this band using logarithmic cycling (approximately 1-1/3 hours in each of three mutually perpendicular directions).在整个频率范围内(从10至500,再从500至10)历时15分钟.在三个互相垂直的方向上各循环12 次(总共36 次),因此整个试验过程历时9 小时.只要能满足振动频率及速度的变化和总的试验时间要求,就允许试验间断进行.只有在一个频段内完成循环后,才允许进入下一频段.在10至55Hz范围内,按照4.1.4 的程序进行振动时,这一频段持续的时间与采用对数循环的时间相同(在三个互相垂直的每一个方向约1.33小时).4.1.6 Test condition III 147.1 m/s2 (15 gn) peak测试条件【峰值：147 .1m/s2(15gn) 】The specimens, while deenergized or operating under the load conditions specified, shall be subjected to the vibration amplitude, frequency range, and duration specified in , and , respectively; see figures 2 and 3.在没有承受或承受规定电负载的情况下,样品承受如、 及所规定的振幅、频率及时间的振动（如图2和图3 所示）。 Amplitude 振幅The specimens shall be subjected to a simple harmonic motion having an amplitude of either1.52 mm (0.06 in) double amplitude (maximum total excursion) or 147.1 m/s2 (15 gn) peak,whichever is less.

This cycle shall be performed 12 times in each of three mutually perpendicular directions (total of 36 times), so that the motion shall be applied for a total period of approximately 12 hours. Interruptions are permitted provided the requirements for rate of change and test duration are met. Completion of cycling within any separate band is permissible before going to the next band. When the procedure (see 4.1.4) of this standard is used for the 10 Hz to 55 Hz band, the duration of this portion shall be the same as the duration for this band using logarithmic cycling (approximately 1-1/3 hours in each of three mutually perpendicular directions).在整个频率范围内(从10至2000,再从2000至10)历时20 分钟。在三个互相垂直的方向上各循环12 次(总共36 次),因此整个试验过程历时12 小时.只要能满足振动频率及速度变化和总的试验时间要求，就允许试验间断进行.只有在一个频段内完成循环后,才允许进入下一频段.在10 至55Hz 范围内，按照4.1.4的程序进行振动时，这一频段持续的时间与采用对数循环的时间相同(在三个互相垂直的每一个方向约1.33小时)。4.1.7 Test condition IV 196.1 m/s2 (20 gn) peak 测试条件【峰值: 196.1 m/s2 (20 gn) 】The specimens, while deenergized or operating under the load conditions specified, shall be subjected to the vibration amplitude, frequency range, and duration specified in , and , respectively; see figures 2 and 3.在没有承受或承受规定电负载的情况下,样品承受如、 及所规定的振幅、频率及时间的振动（如图2和图3 所示）。 Amplitude 振幅The specimens shall be subjected to a simple harmonic motion having an amplitude of either 1.52 mm (0.06 in) double amplitude (maximum total excursion) or 196.1 m/s2 (20 gn) peak, whichever is less. The tolerance on vibration amplitude shall be 10%.样品承受振幅为1.52mm(P-P)或峰值为20g的简谐振动,在两者之间选择振幅较小的一个.振幅的容许误差为10%。 Frequency range 频率The vibration frequency shall be varied logarithmically between the approximate limits of 10 Hzto 2,000 Hz (see 4.1.8).振动频率在10 至2000Hz范围内近似作对数变化(见4.1.8),但在10 至55Hz范围内应按4.1.4中所规定的程序进行。 Sweep time and duration 扫描时间及持续时间The entire frequency range of 10 Hz to 2,000 Hz and return to 10 Hz shall be traversed in 20 minutes. This cycle shall be performed 12 times in each of three mutually perpendicular directions (total of 36 times), so that the motion shall be applied for a total period of approximately 12 hours. Interruptions are permitted provided the requirements for rate of change and test duration are met.在整个频率范围内(从10 至2000，再从2000 至10)历时20 分钟，在三个互相垂直的方向上各循环12 次(总共36次)，因此整个试验过程历时12小时。只要能满足振动频率及速度变化和总的试验时间要求，就允许试验间断进行。Completion of cycling within any separate band is permissible before going to the next band. When the procedure (see 4.1.4.) of this standard is used for the 10 Hz to 55 Hz band, the duration of this portion shall be the same as the duration for this band using logarithmic cycling (approximately 1-1/3 hours in each of three mutually perpendicular directions).只有在一个频段内完成循环后，才允许进入下一频。在10 至55Hz 范围内，按照4.1.4的程序进行振动时，这一频段持续的时间与采用对数循环的时间相同(在三个互相垂直的每一个方向约1.33小时)。4.1.8 Alternative procedure for use of linear in place of logarithmic change of frequency频率的线性变化代替对数变化Linear rate of change of frequency is permissible under the following conditions:在下列条件下，可用频率的线性变化代替对数变化。 The frequency range above 55 Hz shall be subdivided into no fewer than three bands. The ratio of the maximum frequency to the minimum frequency in each band shall be not less than two (2).55Hz 以上的频率范围应再细分为不少于3 个频率.在每一频段里,最高频率与最低频率之比不小于2。 The rate of change of frequency in Hz per minute shall be constant within any one band.在每一频段内,频率的变化速率(Hz/分钟)应是恒定的。 The ratios of the rate of change of frequency of each band to the maximum frequency of that band shall be approximately equal.每一频段的频率变化率与该段的最高频率的比值应大致相等。.1 Example of alternative procedure 替代程序举例As an example of the computation of rates of change, assume that the frequency spectrum has been divided into three bands, 55 Hz to 125 Hz, 125 Hz to 500 Hz and 500 Hz to 2,000 Hz, in accordance with . For each band, let the constant, , represent the frequency change (in Hz/minute), divided by the maximum frequency (in Hz). Then the rates of change for the three bands will be 125, 500 and 2,000, respectively. The times (in minutes) to traverse the three frequency bands areThe required maximum constant rates of frequency change for the three bands are therefore 8.55 Hz per minute, 34.2 Hz per minute and 137 Hz per minute, respectively. The minimum times of traverse of the bands are 8.2 min, 10.9 min and 10.9 min, respectively.按照的规定,假设将整个频段分为55至125,125至500,500至2000Hz三个频段.在每一频段,令频率的变化率与该段频段的最高频率之比值为k，则三个频段的频率变化率分别为125k、500k及2000k，各频段经历的时间分别为（125-55）/（125k）、（500-125）/（500k）和（2000-500）/（2000k）。因为总的扫描时间为30分钟，因此可求出k=0.0687/分钟。三个频段的频率变化率分别为8.55Hz/分钟、34.2Hz/分钟和137Hz/分钟，经过三个频段的时间分别为8.2 分钟、10.9 分钟和10.9分钟.4.2.

The spectral-density values shall be within +40% and -30% (1.5 dB) of the specified values between a lower-specified frequency and 1,000 Hz, and within +100% and -50% (3 dB) of the specified values between 1,000 and an upper-specified frequency (2,000 Hz). A filter bandwidth will be a maximum of 1/3-octave or a frequency of 25 Hz, whichever is greater.以功率频谱密度与频率的关系来表示振动试验机的输出(见.1). 频率位于下限频率与1000Hz之间时，频谱密度的值应介于规定值的+40%和-30%以内(1.5dB). 频率位于1000Hz与上限频率(2000Hz)之间时，频谱密度应介于规定值的+100%和-50%以内(3dB)。滤波器的带宽是最大的1/3 倍频程或者25Hz，选择其中较大的为频宽。.1 Power-spectral density 功率频谱密度Power-spectral density is the mean-square value of an oscillation passed by a narrow-band filter per unit-filter bandwidth
