目前国内外在对拖拉机和机具的试验研究中都广泛采用非电量电测法。这种方法可以在田问测得各另、部件上承受的载荷和应力,压力,加速度以及其它性能参数。这样就要求测试仪器和装置随同被测对象一起在田间运动或采用具有一定作用半径的无线遥测系统。无论是跟随运动还是遥测,都需要有一定形式的田间电测车。我省为粮、棉、油产区,粮食作物以水稻为主,要对水田机具进行电测,条件非常差,采用一般旱地用电测车的形式进行跟踪测试是很难实现的。将仪器由被测对象自载(这种办法只宜于做被测参数较少的试验及某些部件或机具的对比试验。且要求仪器设备重量轻,体
Currently at home and abroad in the experimental study of tractors and machines are widely used in non-electric power measurement method. This method can be measured in the field separately, the components to withstand the load and stress, pressure, acceleration and other performance parameters. This requires that test equipment and devices move with the object in the field or use a wireless telemetry system with a certain radius of action. Whether it is to follow the movement or telemetry, you need to have some form of field electric measurement car. In our province, grain, cotton, oil-producing areas, rice and rice-based foodstuffs, electrical measurements of paddy field machines, the conditions are very poor, the use of general dry-type electric car in the form of tracking test is difficult to achieve. The instrument from the measured object self-loading (this method is only suitable for the test less parameters and comparative tests of certain components or machines, and requires equipment, light weight, body
