| 摘要: |
| 火箭飞行仿真系统作为一个复杂仿真系统，具有多专业强耦合、多偏差模式、连续离散混合仿真等特点，如何保证仿真系统可信度，是一个亟待解决的问题。校核、验证与确认(Verification, Validation and Accreditation, VV&A)是保证火箭飞行仿真系统正确性和可用性的重要方法。系统地总结了VV&A活动各阶段的常用技术和特点，根据VV&A活动一般过程，从工程化角度重点研究了飞行仿真系统VV&A各阶段的具体实现过程，为其他仿真系统VV&A活动提供参考，具有较好的推广应用价值。 |

| Abstract: |
| As a complex simulation system, the launch vehicle flight simulation system features the characteristics of strong coupling of multiple disciplines, multiple deviation failure modes, continuous discrete hybrid simulation, etc How to ensure the credibility of the simulation system is an urgent problem to be solved Verification, Validation and Accreditation(VV&A) is the key technology to ensure the correctness and availability of the launch vehicle flight simulation system This work systematically summarizes the common technical methods and characteristics of each stage of VV&A activities, and focuses on the specific implementation process of each stage of the launch vehicle flight simulation system VV&A process on the basis of general process of VV&A activities from the perspective of engineering This study provides a reference for other simulation system VV&A activities and is of good promotion and application value |
