轻简型稻麦收获机电动智能底盘设计与试验
Design and Experiment of Light and Simple Rice-Wheat Harvesters' Electric Intelligent Chassis
摘要
Abstract
Hilly and mountainous areas are important grain production bases in China.The farmlands in these regions are characterized by small plot sizes,steep slopes,and narrow roads.Traditional fuel-driven chassis have disadvantages such as slow power response,inflexible steering,and low levels of intelligence.To address these issues,an electric intelligent chassis suitable for light and simple rice and wheat harvesters was designed.This machine adopted a distributed design to achieve flexible steering and a wide track design to adapt to rice harvesting operations in hilly and mountainous areas.Motion condition analysis was conducted,and the parameter design of the electric drive system and battery system was completed,solving the problem of slow power response of fuel-powered chassis.The software and hardware design of the motion control system was carried out,enabling remote control operation or autonomous navigation of the chassis.Performance tests and operation parameter optimization tests were conducted.Taking the harvesting speed,threshing drum speed,and cleaning fan speed as test factors,and the breakage rate,impurity rate,and loss rate as evaluation indicators,a Box-Behnken test was designed.The results of the Box-Behnken test were analyzed by variance,and a regression model between the evaluation indicators and the test factors was established.With the goal of minimizing the breakage rate,impurity rate,and loss rate,the optimal solution for the harvesting speed,threshing drum speed,and cleaning fan speed was obtained:the harvester's harvesting speed was 0.8 m/s,the threshing drum speed was 1 000 r/min,and the cleaning fan speed was 2 786.15 r/min.Field tests showed that under this condition,the breakage rate was 0.42％,the impurity rate was 4.05％,and the loss rate was 0.87％.The machine operated smoothly during the operation period,and the operation indicators met the standards for mechanized rice and wheat harvesting.The test results indicated that the designed electric intelligent chassis could meet the operational requirements of the harvester.关键词
