摘　　要：为建立专门的通信指挥车上装设备的等效振动台可靠性试验方法。首先,通过实车多工况道路试验得到真实路谱,对其进行分析处理,根据不同工况下的最大峰值画出功率谱密度曲线图的包络线即可得到规范功率谱。其次,与相关标准规定的实车行驶里程及运行工况相结合,制定出上装设备振动台试验方案。最后,对上装设备进行了振动台试验。结果表明,振动台试验数据与实车道路试验数据拟合较好。研究显示,通过等效振动台试验的方法能够替代实车道路试验,符合通指车辆的实际车辆结构减震特性。Io establish the equivalent vibration table reliability test method for the equipment installed on the communication command vehicle.First of all,the real road spectrum is obtained through the real vehicle multi-mode road test,and it is analyzed and processed.The standard power spectrum can be obtained by drawing the envelope of the power spectrum density curve according to the maximum peak value under different conditions.Secondly,combined with the actual vehicle mileage and operating conditions specified in the relevant standards,a vibration table test plan for the upper equipment was developed.Finally,the shaking table test is carried out for the upper equipment.The results show that the shaking table test data and the real vehicle road test data fit well.The research shows that the equivalent shaking table test method can replace the real vehicle road test,which is in line with the actual vehicle structural damping characteristics of generic vehicles.
