摘要：
By using finite-element analysis theory, we divided wheat into a finite number of units and assumed the displacement of joint between units as unknown, building the lodging-resistant mechanical model of wheat. Combining with the model analysis method, we calculated steady state response caused by harmonic load excitation and analyzed the maximum displacement of Wheat spike at certain wind scale, thereby calculating the maximum lodging bending moment of roots. By comparing it with lodging-resistant, we can evaluate and predict the lodging-resistant ability of wheat. Taking one kind of wheat as calculation example, we calculated the lodging bending moment and lodging-resistant bending moment. The numerical experiment verified the rationality and practicability of model.
