電封閉機械傳動試驗機模擬加載技術(shù)
[摘要]機械傳動試驗機是用來對傳動裝置進行綜合性能測試的試驗平臺。它可以為機械傳動裝置或部件的開發(fā)提供準確而且完備的設(shè)計依據(jù)，并對最終產(chǎn)品的功能進行驗證，對其性能予以評估，是一種多功能的試驗設(shè)備。
針對現(xiàn)有試驗臺存在的一些不足之處，本設(shè)計提出了模擬加載技術(shù)的改造方案，利用計算機控制技術(shù)實現(xiàn)了模擬加載功能的要求。
本設(shè)計首先系統(tǒng)地分析了電封閉機械傳動試驗臺的電氣控制系統(tǒng)各部分的工作原理。在此基礎(chǔ)上，根據(jù)被試件加載功能的要求，從理論上對模擬加載進行了可行性論證，提出了實現(xiàn)模擬加載功能的技術(shù)路線。
試驗表明，本設(shè)計提出的技術(shù)方案切實可行，技術(shù)環(huán)節(jié)的處理合乎需要，可以準確可靠地實現(xiàn)對被試件的模擬加載，并以模擬加載功能為核心實現(xiàn)試驗過程中數(shù)據(jù)的自動采集與處理。該技術(shù)的實現(xiàn)改進了以往試驗臺的不足之處，大大地提高了試驗臺和試驗過程的技術(shù)水平。

ANALOG LOADING TECHNOLOGY OF THE ELECTRICAL POWER CLOSED TESTER OF MECHANICAL DRIVE
[Abstract]The tester of meehanieal drive is an experimental platform used to comprehensively test the capabilities of transmissions.It can provide true and general design gist for the development of mechanieal transmissions and parts and verify the function and performance of the final products，it is a multifunctional device. Therefore,tester is widely used in mechanics，mine，auto and other industries.
Aimed at the defects existing in the current tester,the reconstructive seheme of analog loading is proposed in this paper. Computer control technology is used to realize the requirement of analog loading functions.
Firstly，the principle of the electrical control system of the electrical power closed mechanical drive tester is analyses. On the basis of these analyses，the feasibility of analog loading seheme is demonstrated in theory and the technical route is given according to the requirement of loading function of the test unit.
The results indicate that the scheme is feasible and the technical route is also reasonable and suitable. The analog loading to the test unit can be realized exaetly and stably， also the data acquiring & processing can be completed automatically. The realization of analog loading has amended the shortcomings of the original tester and greatly improved the technical level of the tester.
Keywords: Mechanieal drive Analog loading Computer control technology Tester
