摘要:
为了研究自行火炮行进间炮口振动频率特性,建立了某自行火炮刚柔耦合多体系统动力学方程。考虑到身管柔性对炮口扰动的影响,在HyperMesh有限元软件中计算获得柔性身管约束模态并生成中性文件,利用ADAMS/ATV履带工具箱建立了该自行火炮刚柔耦合动力学模型。针对实际行驶工况,运用谐波叠加法编写路面谱程序并生成路面文件,对E、F、G级道路进行了模拟,获得了自行火炮在不同等级道路上以不同速度行驶时的炮口动态响应。利用快速傅里叶变换得到炮口角加速度功率谱密度曲线。通过分析对比,确定了柔性身管炮口在不同行驶工况下的振动频域范围。
Abstract:
To study the characteristics of muzzle vibration frequency for the self-propelled gun on move,the rigid-flexible coupling dynamic equations are established.The constraint mode of the flexible tube is calculated and the model neutral file(MNF)is generated by Hypermesh.The rigid-flexible coupling dynamics model of the gun is set up by ATV toolbox of ADAMS.The stochastic road irregularities file is made by using the sinusoid superposition method.Road spectrum of rank E,F and G is simulated based on the road file generated by Matlab software.The muzzle dynamic response of self-propelled guns moving on the different rank roads at different speeds is obtained.Utilizing fast Fourier transform(FFT)method,the power spectral density of muzzle angular acceleration is gained.After analysis and comparation,the muzzle vibration frequency ranges at different road irregularities and speeds are determined.
