| 摘 要： | 本文采用拉格朗日方法研究了牵引榴弹炮在牵引行驶状况下的动力学问题。建立了具有三维23个自由度的动力学模型。编制了相应的模拟道路不平度输入程序。研究了在不同道路上行驶时的动力学响应特性和离散激励下的动力学响应的分析方法。并以牵引榴弹炮上的一些敏感和薄弱部位的动力学响应为例进行了试验验证。理论计算和试验结果符合较好。该研究为开展火炮牵引试验提供了一种新的方法。

| Abstract: | The running dynamical response of a towed howitzer was studied applying the Lagrangian method. A dynamical model having 23 degrees of freedom was given to study the response caused by road irregularities. A computer program has been written for the simulation of response on various road conditions and analysis of dynamical response at the discrete excitation. Attention was paid to the response of some critical parts of the howitzer. Tests were carried out to validate the results, and the test results are in good accord with the results of calculation. |
