Mechanical model of wheat and vibration analysis

By using multi-freedom systems vibration theory, the mechanical model of wheat lodging resistance is established, the wheat lodging moment formula is deduced under the wind load. Considering the soil characteristics and the wheat root distribution, the wheat moment of lodging resistance is deduced, The moment the size of these two can predict whether wheat is lodging, Vibration mode analysis explain the reasons for the differences of the different varieties of wheat lodging resistance. Wheat numerical examples verify the rationality and practicality of the model.
