摘要
针对大型导弹车在运输状态下的动态特性识别问题,设计制作了能够反映大型导弹车主要动力学特征的简化模型,使用最小二乘复指数法(LSCE)对简化模型进行了动态特性识别,对识别结果进行了分析和评估,并将最小二乘复指数法应用到真实大型导弹车运输状态的模态识别中。可为大型导弹车运输状态下的动力学特性分析提供参考。
To solve some problems of the operational modal identification of large missile launch vehicle,a model reflecting the main dynamic characteristics of large missile launch vehicle was made.Modal experiments were conducted and dynamic characteristics of the model were identified using the Least Square Complex Exponent（LSCE） method.Modal identification results were compared and analyzed to evaluate the LSCE method.It was applied to the operational modal identification of large missile launch vehicle.It is of significance to provide references for the dynamic characteristics analysis of large missile launch vehicle.
