A continuously variable transmission test bench is built . an autocontrolling software about continuously variable transmission system is developed , the data of engine throttle opening , speed ratio of cvt and load can be gathered in test bench and the system can be controlled 搭建了無級變速傳動系統(tǒng)實(shí)驗(yàn)臺,開發(fā)了無級變速傳動自動控制軟件,在實(shí)驗(yàn)臺上實(shí)現(xiàn)了發(fā)動機(jī)節(jié)氣門開度、無級變速器速比及載荷等數(shù)據(jù)的采集及計(jì)算機(jī)自動控制。
5 . according to the requirement of amt start up experiment , using dynamic link library to program for different kinds of data acquisition card and transferring data between pc and multi scm . in this way data can be acquired successfully and engine throttle 、 clutch locking speed and eddycurrent dynamometer torque were controlled by pc programs 根據(jù)試驗(yàn)要求,采用動態(tài)鏈接庫的方法對不同數(shù)據(jù)采集卡進(jìn)行混合編程,順利地采集參數(shù)和控制發(fā)動機(jī)節(jié)氣門開度及離合器結(jié)合速度,利用上下位機(jī)多機(jī)通信,使上位機(jī)控制電渦流測功機(jī),實(shí)現(xiàn)了模擬加載。
