摘　　要：传统的防逆转装置存在体积与质量大的缺点,不适用于对质量指标极度敏感的航空类产品。为此,提出一种小巧轻便的新型矩形截面弹簧逆止器设计方法,通过对逆止器中矩形截面弹簧进行力学分析,明确矩形截面弹簧的受力与变形关系,分析矩形截面弹簧尺寸、配合套筒过盈量与逆止性能的变化特性。推导矩形截面弹簧逆止器逆止有效条件,并引入遗传算法进行求解;根据求得的结构参数,运用CATIA软件建立矩形截面弹簧逆止器结构模型,并导入HyperWorks软件进行校核分析。结合样件试制及测试,结果表明:所提方法与传统摩擦盘式方法相比同负载条件下质量可降低约61%,仿真与实验对照验证所提方法的有效性。Due to its bulk and weight,the conventional anti-reverse mechanism is not appropriate for use in aircraft items that are very responsive to weight indicators.In this paper,a design method for the small and lightweight rectangular cross-section spring anti-reverse device is proposed.Through the mechanical analysis of the rectangular cross-section spring in the anti-reverse device,the relationship between the force and deformation of the rectangular cross-section spring is deduced.The anti-reverse performance with the size of the rectangular cross-section spring and the interference with the matching sleeve is studied.Genetic algorithms are used to determine and resolve the effective working conditions of the spring anti-reverse device with a rectangular cross-section.The structural model of the rectangular cross-section spring anti-reverse rotation device is established by CATIA software,which is imported into HyperWorks software for verification analysis.By the manufacture and measurement results of the designed prototype,it is shown that the weight of the rectangular section spring anti-reverse device designed based on this study can be reduced by 60%compared with the traditional friction disc type under the same load condition.The correctness and reliability of the design method are verified by comparing the simulation results with the experimental data.
