摘要
高速飞行器的多物理场耦合仿真是一个高度耦合、高度非线性的过程,传统的做法就是把专业模型采用工程算法、经验算法取代,但这种过度简化又降低了仿真结果的精度,因此,需要根据多物理场各耦合模型的特点,开展有效的简化方法研究。在实践中,通过多物理场耦合仿真的研究,关注主要矛盾和工程需求,忽略次要矛盾,根据不同的耦合特点和应用需求,提出了耦合仿真的简化方法和结论,并通过算例进行了验证。
Multi-physics coupling simulation of aircraft is a highly coupled and advanced nonlinear process.Traditionally,the data of professional model was collected through engineering algorithm,experience.The over-simplified approach reduced the accuracy of the simulation result.Therefore,a simplified but effective approach according to the characteristics of each multi-physics coupling model needed to be found.Through multi-physics coupling simulation research which focused on the main contradictions and engineering requirements,ignores minor contradictions,depending on characteristics of the various couplings and application requirements,the simplified approach and conclusions were put forward and verified by examples.
