基于AVR单片机的机车弹簧测试仪的设计

以AVR单片机作为主控单元，结合机械设计技术、电子技术、电机控制技术等，设计了一套机车单元制动器缓解弹簧的测试系统，它能够自动完成对缓解弹簧刚度和自由高的检测，并根据检测结果判断其性能是否满足使用要求，并能够打印出检测结果。

Design of Drive Spring Test Instrument Based On AVR Microcontroller

Take AVR microcontrollers as master units and design a set of testing system for brake springs through a combination of mechanical design technique,electronic technique and motor technique.Such testing system can automatically check the rigidity and free height of brake springs,estimate their function whether or not to meet the use requirements,and print out the result as well.
