| 摘 要： | 拖拉机只有工作在容许滑转率条件下才能充分发挥自身的驱动能力,保证较高的牵引效率和工作效率.为了使作业人员能够及时获得滑转率信息,以保证拖拉机工作在容许滑转率附近,必须对拖拉机滑转率进行实时测量,而车身速度的实时与准确测量则是拖拉机滑转率测量的关键.传统的采用五轮仪测量拖拉机车身速度的方法只适用于测试实验系统,而不适合控制系统.为此,针对滑转率测量要求和拖拉机的复杂工作环境,介绍了车速的实时测量方法以及相应的测量原理和测量过程.在此基础上,对各种测量方法的实用性进行了分析,以期对相关领域的工作人员在以后的研究工作和实际应用中有所帮助.

| Abstract: | To achieve full use of its driving force and have high efficiency,tractor must work at the tolerant accelerating slip ratio.Accordingly,timely acquisition of slip ratio information becomes necessary,which puts forward the demand for in-time measurement of slip ratio.And real-time and accurate vehicle velocity is the key and difficultly-obtained parameter in real-timely calculating tractor accelerating slip ratio.Traditional fifth-wheel is suitable only for testing system,not for controlling system.To find p... |
