动力学

The adjoint variable method for design sensitivity analysis of multibody system dynamics based on ordinary differential equations is presented.

基于常微分方程数学模型建立了多体系统动力学设计灵敏度分析的伴随变量方法。

The second is that meshcan be fine as required for we have solved the conventional problem that the shell'smesh must be limited in notch.Moreover,the mesh size's significance to the resultsis displayed by calculation and compare of models with different mesh sizes.Besides,we have simulated the cloud-shaped field distribution of moving FAE Devices with adynamic program.The results can provide the elementary basis for structure designadapted to new launching conditions.

二是突破了传统的壳体网格划分只能沿刻槽的限制，使网格可以细化，并通过不同网格尺寸的模型计算与比较，显示了网格划分对结果的影响程度；此外，使用自行编制的动力学程序，对运动FAE装置云雾场分布规律做了简化的数值模拟，为工程部门提供了在新的发射条件下改进弹体结构设计的初步依据。
