摘　　要：设计了一种车载天线阵面运输减震装置,建立了减震装置的理论模型,通过更改阻尼比得到欠阻尼系统、临界阻尼系统和过阻尼系统,基于这3种系统分别使用MATLAB和ABAQUS仿真计算软件共同仿真在一定的路面冲击下天线阵面的位移响应和速度响应,并绘出冲击过程和自由振动过程的响应曲线。两种软件有着各自的优势,均适用于振动冲击分析,可互相进行验证。结果表明:两种软件分析结果一致性高,欠阻尼系统更符合某车载雷达天线阵面的运输工况,并在实际中得到了应用。It designs the damping support of the vehicle-mounted array radar,establishes the theoretical model of the damping device.By changing the damping ratio,under damping system,critical damping system and over damping system can be obtained.MATLAB and ABAQUS software are used to simulate the displacement response and velocity response of antenna array under certain road impact.And it obtains response curves of the impact process and free vibration process.Both software have their own advantages and are suitable for vibration and impact analysis,and verify each other.The results of these analysis software are consistent.The underdamped system is more consistent with the transportation condition of the vehicle-mounted array radar and it has been applied in practice.
