悬挂犁传统受力分析方法的质疑和计算机辅助分析

QUERYING OF TRADITIONAL METHOD TO ANALYZE THE FORCES ACTED ON THREE HITCH PLOUG PLOUGH AND COMPUTE AIDED ANALYZING OF THE FORCES

对悬挂犁受力分析的传统方法提出了质疑，并从理论上分析了存在问题的原因。用解析方法建立了悬挂犁受力方程组，编制了计算机程序，依靠计算结果，探讨了各因素变化对悬挂犁所受作用力和力偶矩的影响。

In this paper, the traditional method to analyze the forces acted on three hitch plough wasqueried, and its errors were pointed out and the reason resulting in the errors was researchedin theory.3-D balance equations of the forces applied to the plough were set up and pro-grammed. On the basis of the result of calculation the influence of different values of the fac-tors on forces and torque acted on the plough was evaluated.
