摘要/Abstract

摘要： 为了研究冷发射装备对地载荷作用下场坪的动力响应，将对地载荷视为多圆均布动载荷，基于赫兹接触理论获得对地载荷的表达式。以Winkler地基上双层板的控制微分方程为基础，引入双参数地基模型中的地基反力，给出双参数地基模型上双层板的运动微分方程。采用级数分解与傅里叶变换相结合的方法推导单个圆形载荷下场坪挠度的解析式，利用线性叠加方法，得到多个圆形均布动载荷下场坪下沉量的表达式。在ADAMS中建立含场坪的发射装备动力学模型与Simulink进行联合求解，获得各个接触区域圆心处的场坪下沉量，分析结果表明：底座处的场坪下沉量较大且对后两个支撑盘处下沉量产生很大影响；支撑盘之间下沉量的相互影响很小，可忽略。

Abstract: In order to research the dynamic response of old launching equipment to prepared launching site subjected to loading, the loading is regarded as multi-circle distributed force, and the expression of force is derived based on Hertz contact theory. Based on the governing differential equation of Winkler foundation model, the differential equations of two-layer plate are improved by adding the subgrade reaction into the two-parameter foundation model. Then the expression of launching site deflection under single-circle distributed force is deduced by using Fourier integral transformation and triangular series methods. The analysis formula of settlement under multi-circle distributed force could be got by using linear superposition method. For the sake of settlement of launching site, a co-simulation dynamic model of launching equipment including site is built by ADAMS software and Simulink software. Analysis results of the settlement of circle center in every contact area show that the settlement of contact area at the base is larger and has great impact on the deflections of the latter two contact areas of support disk, the settlement interact between support disks should be ignored because of small order magnitude.

Key words: ordnance science and technology, launching equipment, multi-circle distributed dynamic force, two-layer plate model on two-parameter foundation, co-simulation, settlement of launching site
