A JACK-Based Ergonomic Analysis and Design of the Cockpit of Agricultural Material Handling Vehicle

Abstract

The JACK ergonomic analysis software was used to simulate and analyze the driver’s driving posture and operating behaviors in the cockpit to simulate and optimize the driving comfort of the driver operating a certain model of agricultural material handling vehicle. Through simulation and analysis of the six tools, Comfort Assessment, Lower Back Analysis, Static Strength Prediction, Etc., it was found that the vehicle cockpit’s curve of the waist part of the seat was reasonable, but the design had poor comfort levels on the shoulder and neck part, which not only caused fatigue when the vehicle was operated for a long period of time, but also made it challenging for the knees and ankles from sustaining prolonged work at the cockpit. On this basis, the research proposed ergonomic optimization and improvement was also conducted. The research provides a significant basis of reference for designing the cockpits of special-purpose agricultural vehicles.
