摘　　要：立足民用飞机运行场景,结合适航规章,提出一种以需求为导向的飞机系统正向设计方法。以飞机机轮刹车系统蓄压器刹车为例,分析利益相关方的需要,定义系统蓄压器相关需求,并对蓄压器刹车过程进行分析和计算。基于MATLAB/Apps平台建立蓄压器刹车系统通用仿真软件,对系统蓄压器相关需求进行基于模型的确认。最后,基于Simscape和Simulink平台建立机轮刹车系统的多学科集成模型,用于蓄压器刹车系统协同仿真,对系统蓄压器相关需求进行基于模型的验证。以需求为导向构建的正向设计方法,在系统初步设计阶段完成了需求定义,并通过模型完成了需求的确认与验证,降低了系统研制风险。Based on civil aircraft operation scenario and airworthiness regulations,a requirement-oriented forward design method for civil aircraft system was proposed.Taking the accumulator brake of aircraft wheel brake system as an example,the needs of stakeholders was analyzed to define the requirements of accumulator brake system,then the process of accumulator brake was analyzed and calculated.The general simulation software of accumulator brake system was established based on MATLAB/Apps platform,and the requirements of accumulator brake were validated based on model.Finally,a multidisciplinary integrated model of wheel brake system was established based on Simscape and Simulink platform for the collaborative simulation of the accumulator brake system,and the requirements of accumulator brake were verified based on model.By using the forward design method constructed based on requirement,the requirements definition is completed in the preliminary design phase,the validation and verification of requirement is completed through the model,reducing the risk of system development.
