Innovative Magnetorheological Suspension Systems for Forklift Trucks

本项目旨在改进叉车设计，以减少叉车驾驶员所经历的振动。研究一致认为，由于传统叉车刚性被动悬架导致的手部、手臂和全身振动，导致驾驶叉车时背部疼痛和肌肉骨骼损伤的发生率很高，而传统叉车的刚性被动悬架无法适当吸收驾驶表面偏差、质量变化或常见装卸动作引起的振动。该项目旨在利用研究团队在磁流变技术方面的专业知识，开发和评估一种新的可调集成半主动车轮、底盘和座椅悬架系统，该系统可以改变阻尼和刚度，以控制质量不确定性和振动。

This project aims to improve forklift design to reduce the vibration experienced by forklift drivers. Research consistently links forklift driving with a high incidence of back pain and musculoskeletal injuries through exposure to hand, arm and whole-body vibrations that are caused by the rigid passive suspension in traditional forklifts, which cannot properly absorb vibration stemming from deviations in driving surfaces, changes in mass, or common loading, lifting and unloading actions. The project aims to draw on the research team’s expertise in magnetorheological technology to develop and evaluate a new tuneable integrated semi-active wheel and chassis and seat suspension system that can vary damping and stiffness to control mass uncertainty and vibration.
