摘要
车载物资或设备振动环境谱的数据处理与归纳是车载物资或设备环境可靠性试验的重要组成部分,对保障车载物资或设备的完整性和可靠性具有十分重要的意义。以货车为例,依据GB 10593.3-90进行数据合并,然后采用统计容差法进行振动环境条件随机振动规范谱的估计。所得到的规范谱为车载物资或设备振动环境的可靠性评定奠定了基础。
The data processing and induction of vibration environmental spectrum is an important part of environmental reliability test for commodity or equipment carried on truck. It has great significance for guaranteeing the security and reliability of commodity or equipment carried on truck. Truck was taken as an example; test data were incorporated according to GB10593.3-90; random vibration spectra were estimated by means of statistic admissible error method for vibration environment condition. The purpose was to establish a foundation for reliability assessment of vibration environment for commodity or equipment carried on truck.
