| 目的建立模拟试验谱推导方法，合理确定车载仪器设备模拟振动试验条件。方法针对履带车辆平台诱发环境实测振动数据，通过履带车辆实测振动谱环境特征分析，提出宽带随机振动背景谱叠加窄带分量作为模拟试验谱的基本谱形，并探讨相应试验量级和试验时间的推导方法。结果建立了由实测振动数据推导模拟试验谱的方法。结论模拟试验谱推导方法实用性强，依据此方法由某履带车辆实测数据得到了相应的模拟试验谱。 |

| ObjectiveTo establish the method inducing simulating test spectrum, in order to reasonably determine the simulated vibration test conditions of vehicle equipment. MethodsBased on the measured vibration data of tracked vehicles induced environment, the environment description of measured vibration spectrum was analyzed，narrow bands on broadband random was introduced as the basic spectrum of simulating test spectrum，and the method of inducing test level and test duration was studied.ResultsThe method inducing simulating test spectrum from the measured vibration data was established. ConclusionThe method deducing the simulating test spectrum was practical. Based on the method，corresponding simulating test spectrum was induced by measured data of tracked vehicle. |
