汽车变速器性能试验台自动控制

目的实现汽车变速器性能试验台自动控制，方法采用了润滑油油温自动恒温控制技术，微机控制变速器自动换档、动力电机无级调速、加载电涡流测功机变载、试验数据的自动采集与实时处理技术，结果润滑油油温控制在设定温度±２℃；自动换档简单、可靠、准确；无级调速调载快速准确，加载转矩偏差为±１Ｎ．ｍ，输入转速偏差为±５ｒ／ｍｉｎ，结论将上述技术应用于汽车变速器性能试验台，利用该试验台对某型变速器进行了微机程控性能试验，效果良好。

Automatic Control of Automobile Transmission Performance Test Stand

To realize automatic control of automobile transmission performance test stand Methods The automatic control technique of the lubricant temperature,the program- controll- edautomaticshifting of the transmission,the continuous adjusting of revolution speed and load, data-acquisition and data real-time processing were adopted.Results The lubricant temperature was controlled at the set temperature ±2℃.The automatic shifting of the trans- mission is simple,reliable and accurate.The automatic adjusting of load and rotation speed is rapidandaccurate,the torque divergence is ±1N·m,the rotation speed divergence is ±5r/min Conclusion The four kinds of techniques are applied into the automobile transmission perfor- mance test stand successfully. mancetest stand successfully.
