長(zhǎng) 春 大 學(xué) 畢業(yè)設(shè)計(jì)（論文）紙
電封閉機(jī)械傳動(dòng)試驗(yàn)機(jī)模擬加載技術(shù)
[摘要]機(jī)械傳動(dòng)試驗(yàn)機(jī)是用來(lái)對(duì)傳動(dòng)裝置進(jìn)行綜合性能測(cè)試的試驗(yàn)平臺(tái)。它可以為機(jī)械傳動(dòng)裝置或部件的開(kāi)發(fā)提供準(zhǔn)確而且完備的設(shè)計(jì)依據(jù)，并對(duì)最終產(chǎn)品的功能進(jìn)行驗(yàn)證，對(duì)其性能予以評(píng)估，是一種多功能的試驗(yàn)設(shè)備。
針對(duì)現(xiàn)有試驗(yàn)臺(tái)存在的一些不足之處，本設(shè)計(jì)提出了模擬加載技術(shù)的改造方案，利用計(jì)算機(jī)控制技術(shù)實(shí)現(xiàn)了模擬加載功能的要求。
本設(shè)計(jì)首先系統(tǒng)地分析了電封閉機(jī)械傳動(dòng)試驗(yàn)臺(tái)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(duì)模擬加載進(jìn)行了可行性論證，提出了實(shí)現(xiàn)模擬加載功能的技術(shù)路線。
試驗(yàn)表明，本設(shè)計(jì)提出的技術(shù)方案切實(shí)可行，技術(shù)環(huán)節(jié)的處理合乎需要，可以準(zhǔn)確可靠地實(shí)現(xiàn)對(duì)被試件的模擬加載，并以模擬加載功能為核心實(shí)現(xiàn)試驗(yàn)過(guò)程中數(shù)據(jù)的自動(dòng)采集與處理。該技術(shù)的實(shí)現(xiàn)改進(jìn)了以往試驗(yàn)臺(tái)的不足之處，大大地提高了試驗(yàn)臺(tái)和試驗(yàn)過(guò)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
