Abstract


The topic is the subject of the Sino-Australian cooperation is an integral part of the \The subject of the use of virtual instrument technology composed of two different test system , seen by the two systems : virtual instrument technology to reduce the cost of the system components . The test requires the development of the field test vehicle , use LabWindows / CVI preparation of signal acquisition and data analysis procedures , improve test accuracy , saving the time of the data processing . The results showed that : the existing opener type , the ditching resistance of the short wing opener is the smallest , in order to reduce the resistance to traction on a small tractor narrow no-tillage planter should be used in short airfoil opener . The test results also show that : field resistance test signal is a low frequency random signal , the sampling frequency should not be less than 4Hz . Planter field vibration spectrum analysis , vibration characteristics . Estimated the transfer function in planter mode excitation test .
