- In this article , the process of linear departing installation by fire work is mumerically simulated by ansys / ls - dyna , and discusses how to increase the accurateness of numerical simulation
本文采用ansys / ls - dyna软件对线性火工分离装置的爆炸过程进行数值模拟,并通过对数值模拟理论的分析和比较,探讨了进一步提高数值模拟准确性的方法。 - However , in order to satisfy students that have mastered the previous work , those who are anxious to build further , but lack points of “ starting ” , i shall bring thoughts and ideas , which run up like fire works into the sky
不过,为了满足学生对已掌握的前期工作,那些急欲进一步建立,但由于缺少点"开始" ,我将想法和意见跑起来像消防工程直冲云霄 - Whether the long - range aerocraft can complete the flight mission has the direct relation with the performance of the fire work departing installation , so it has the great reality significance to optimize the structure of space navigation departing installation
火工分离装置工作性能的好坏直接关系到远程飞行器完成飞行任务的成功与否,因此对宇航火工分离装置进行结构优化具有重大的现实意义。 - Since the departing process of fire work departing installation is a highly nonlinear transient dynamic process , it relates to many speciality field , and the characteristic of the material is very complex under the highly rate and highly pressure distortion , the design methods and the design formulae by experience which has been used for a long time are very limited , the facter which truly affect the departing process of fire work departing installation cannot been reflected in the design calculation , the structure modelling and optimization of the fire work departing installation is cannot been carried out by the traditional optimization method
由于火工分离装置的分离解锁过程是一个高度非线性的瞬态动力过程,涉及多个学科和专业领域,而且材料在高速高压条件下瞬时性态十分复杂,长期以来所沿用的经验设计方法和设计经验公式的局限性很大,对火工分离装置分离解锁过程一些实际有影响的因素不能定量地反映到设计计算中来,采用传统优化方法无法实现火工分离装置的结构优化建模和计算。 - In this paper the response surface method ( rsm ) is introduced into the structure optimization of linear fire work departing installation , which make the target fuction explicit , adopt the big finite element procedure to numerically simulate the departing process of the fire work departing installation instead of the expensive substance experiment , establish reasonable optimization model and resolve it , the final result is satisfied , and analyse the question presented during optimization process in detail
