单轨火箭橇滚转效应预示方法

Research on Rolling Effect Predictable Method of Monorail Rocket Sled

提出了一种基于动力学仿真和数值分析的滚转特性预示方法,运用显式动力学分析理论,加载模拟真实环境,动力学仿真数据经数值变换映射为火箭橇滚转特性,时效性强;该方法一致性偏差可以控制在10%以内。

A predictable method of rolling characteristics based on dynamic simulation and numerical analysis was proposed.Owing to the using of explicit dynamic analysis theory,the loading of the conditions and parameters of simulating the real environment of it was effective because that the rolling characteristics of rocket sled were transformed by numerical transformation of dynamic simulation data.After prediction analysis of simulation example and data verification of test case,the actual consistency deviation of this method can be controlled within 10%.
