目前,应用传动系统室内疲劳试验来部分取代田间长期使用试验已受到充分重视,并已得到广泛应用.但其加载方法上还存在局限性,主要缺点是在很大程度上不能再现田间使用载荷型式,因而还不能用室内台架试验完全取代田间使用试验。图1为铁牛-650拖拉机左右半轴的实测扭矩。作业地点为天津市西郊;土壤情况为粘土麦茬地;作业项目为耕地:拖拉机耕作速度为7.09公里/小时。
Currently, the application of transmission system indoor fatigue test to partially replace field long-term use test has been given full attention and has been widely used.But its loading method there are still limitations, the main drawback is to a large extent can not reproduce the field use of load type , And therefore can not completely replace the field use test indoor bench test. Figure 1 for the tractor about half-axle tractor torque measured. The working site is in the western suburbs of Tianjin. The soil condition is clay stubble. The project is farmland: the tractor cultivates at a speed of 7.09 km / h.
