    摘要:

    摘要:艦載機著(zhù)艦時(shí)將對攔阻系統產(chǎn)生很大的沖擊載荷,風(fēng)險極高,需要評估艦載機攔阻系統特性。建立大型非標艦載機攔阻系統試驗臺是驗證艦載機攔阻系統特性的重要方法。以前的試驗臺多采用電機驅動(dòng)形式,存在難以達到預期的加載力及速度的問(wèn)題,該系統改用液壓泵站加蓄能器作為動(dòng)力源的試驗臺,解決了高速液壓缸的測控問(wèn)題。該系統采用了RTOS(Real Time Operating System)實(shí)時(shí)操作系統(以下簡(jiǎn)稱(chēng)RT),運用上下位機模式及Labview編程語(yǔ)言,實(shí)現了試驗臺液壓缸高速運動(dòng)控制,以及液壓缸在大速度大載荷下的穩定控制。設計的系統實(shí)現對攔阻索施加(0~900)KN連續可調的加載力,(0~9)m/s連續可調的滑行速度,100°~180°連續可調的角度。試驗結果可為艦載機攔阻系統中攔截索的特性評估提供數據支持。

    Abstract:

    Abstract: There will be a great impact load on the arresting system when the carrier aircraft landing the ship, and the risk is extremely high. the characteristics of the aircraft arresting system must be estimated. The establishment of a large non-standard test stand for arresting system of the carrier aircraft is an important method to verify the characteristics of aircraft arresting system. In order to solve the problem of motor driving in the former test stand, hydraulic pump station and hydraulic accumulator are used in this design. The problem of measuring and controlling of high speed hydraulic cylinder is solved. In this system, the RTOS(Real Time Operating system)、 the mode of host computer and slave computer and the programming language of Labview are used to realize the high-speed motion control of the hydraulic cylinder. The stability control of hydraulic cylinder under large speed and load is realized. The system is designed to apply a continuous adjustable loading force from 0KN to 90KN, continuously adjustable sliding speed from 0 m/s to 9m/s, and continuously adjustable angle from 100°~180°.The test results can provide data support for the evaluation of the characteristics of aircraft arresting system.
