航空发动机成附件橡胶件的“积木式”试验设计

Aero Engine into Accessory Rubber Parts of the “Building Block” Test Design

在飞机结构“积木式”试验的基础上,提出了针对航空发动机成附件橡胶件元件级、模拟件级、工装级和系统级试样的四级“积木式”试验。明确了各级试验的试验对象、主要任务、试验目的和基本试验思路。提出了在系统级试验的开展中,保证橡胶件的结构状态、安装状态与实际工作情况一致的方法,以及“工况谱”编制的主要内容。将“积木式”试验流程应用到橡胶材料中,为新型航空发动机成附件橡胶件的设计研制提供帮助。

Four“building block”tests are proposed for rubber parts of aero-engine accessories at component level,simula-tion level,tooling level and system level.The main tasks of tests at all levels are defined.The method of ensuring the structure state and installation state of rubber parts are consistent with the actual working condition in the system-level test is put forward.The“building block”test process is applied to rubber materials,which provides help for the design and development of rubber parts for new aero-engine accessories.
