装备典型舰载平台振动环境严酷度分析

目的为了正确识别舰载环境。方法采用INV3062T2数据采集系统,在典型舰载平台上实测了装备在舱室内的振动环境。结果数据表明,舱室内各方向上的振动加速度是一个正态随机变量,得到了各方向加速度峰值和振动加速度谱密度。结论分析表明,舱室内典型振动环境属于I型,是一类长期存在但量值较小的振动环境。

Severity Analysis of Typical Shipboard Vibration Environment for Materiel

Objective To correctly recognize the shipboard environment. Methods The vibration environment of the materiel in the cabinet was measured on a typical shipboard platform using the INV3062T2 data collecting system. Results The vibration data showed that the vibration accelerated velocity in all directions of the cabinet was a normal random variable, and the peak accelerated velocities as well as the accelerated spectral densities in all directions were also obtained. Conclusion The analysis showed that the cabinet vibration environment belonged to type I vibration, which is a low-value and long-term vibration environment.
