摘　　要：目的研究战术导弹在公路机动运输环境下振动试验条件的制定。方法根据某型导弹实地跑车试验测量数据,采用时域统计分析和频域功率谱分析的方法,在基于悬挂频率、轮胎频率、导弹约束状态频率或车架大梁频率和弹上设备安装频率或舱段频率等四类主要频率进行修正的基础上,合理地制定了战术导弹公路机动运输振动环境条件。结果利用本文方法预测弹上和车上设备的振动环境条件,并与试验场跑车试验结果对比分析表明,本文方法正确、合理,具有较高的工程应用价值。结论通过与GJB150A和MIL810G的对比分析表明,本文方法灵活、方便,能够适应于不同种类的产品或设备。Objective To study the formulation of vibration test condition for tactical missile in highway mobile transportenvironment. Method According to measurement data of transportation test on a tactical missile, statistical analysisand power spectrum analysis were taken to establish the tactical missile highway and off-road transportation vibrationenvironment condition on the basis of four types of main frequencies, including frequency of suspension, frequency oftire, constraint frequency of missile and frequency of equipment installation. Results The method presented in this paperpredicted the vibration environment conditions of navigation system in missile and control host in launching truck. Theresult was compared with test result on sports car in the test site. It showed that the method was correct and reasonable.Conclusion By the contrasts with GJB150A and MIL810G, it shows that the method is flexible and convenient, and canadapt to the different equipment in missile and launching truck.
