机滚船犁耕作业的转弯稳定性研究

为了解决机滚船犁耕作业转弯时的横向倾翻问题，采用理论计算与水田试验相结合的方法，通过对机滚船犁耕作业时的运动学和动力学分析，从稳定性角度出发，建立数学模型。经过分析和计算，求出了机滚船犁耕作业时最小转弯半径的关系表达式，将其运用到1BG-0.9型带铧式犁机滚船上，计算出了该机滚船的最小转弯半径。通过水田试验，确定了该机滚船转弯时不发生横向倾翻的最小转弯半径和最大转向角，保证了其转弯稳定性。研究结果为该类机滚船的设计开发提供了充分的理论依据。

Turning stability of the paddy field boat during cultivation operation

To solve the problem of transversal turnover of the paddy field boat during the cultivation operation, combining the method of theoretical calculation with paddy field test, the kinetic and dynamic characteristics were analyzed and the mathematical model was established according to movement stability in this paper. Through analyzing and calculating, the relationship expression of the minimum turning radius based on this model was concluded. Applying this theory to 1BG-0.9 paddy field boat with bottom plow, the minimum turning radius was figured out. The minimum turning radius and the maximum turning angle were determined through paddy field testing and the stability was ensured. This study provided theoretical basis for designing and developing this kind of machine.
