Optimization of Human-machine Interface for Small Tractor Control Console Based on Psychological Load Test of Agricultural Machinery Operators
In response to the problem that insufficient engineering design on the tractor control panel can lead to high psychological burden and easy misoperation of drivers when small tractors are working in mountainous areas,ergonomic experiments are conducted to optimize the tractor control panel to improve the comfort of tractor operation and reduce the psychological burden of operators in complex working conditions.Firstly,the subjective measurement method of psychological load is used to conduct human-machine semi physical psychological experiments.Then,a principal component model of driver psychological load is established.Then,the optimization method is analyzed using the theory of human-machine engineering.Finally,an experimental verification of tractor control panel optimization design is carried out.The results indicate that the physiological load on the driver's head and neck is relatively high,leading to an increase in psychological load during work;after optimization,the control panel can significantly reduce 44.80％of the psychological load on homework.
