摘要

摘要在印度，腰果脱壳是所有小规模腰果加工行业的一项重要任务。从事中枢神经系统任务的工人通常以尴尬的站立姿势操作踏板操作的腰果剥壳机（CNSR），这可能会导致与工作相关的肌肉骨骼疾病（MSD）。然而，从工效学角度进行的调查几乎没有在印度小规模腰果加工行业进行。因此，本研究旨在评估中枢神经系统任务中的姿势工作量，以提出小规模腰果加工行业的人机工程学设计干预措施。采用了多种方法，包括姿势记录、姿势评估、访谈、问卷调查、虚拟样机以及数字人体建模和模拟。使用踏板操作的CNSR导致MSD的高风险姿势。基于这些初步发现，设计了一种简单、改进和可调节的手动CNSR，并对其进行了人体工程学评估。研究发现，新设计的CNSR显著改善了姿势，为工人提供了舒适感。

Ergonomic design and simulation-based evaluation of a new cashew nut sheller

ABSTRACT In India, the cashew nut shelling (CNS) is an important task in all small-scale cashew nut processing industries. Workers engaged in CNS task commonly operate pedal-operated cashew nut sheller (CNSR) in awkward standing posture that can contribute to work-related musculoskeletal disorders (MSDs). However, investigations from an ergonomics perspective have barely been conducted in Indian small-scale cashew nut processing industries. Therefore, the present study aims to evaluate the postural workload in CNS task to propose an ergonomic design intervention in small-scale cashew nut processing industries. A combination of methods, including posture recording, postural assessment, interviews, questionnaire study, virtual prototyping, and digital human modeling and simulation, were used. Using the pedal-operated CNSR resulted in high-risk postures of MSDs. Based on these preliminary findings, a simple, improved, and adjustable hand-operated CNSR was designed and evaluated ergonomically. It was found that newly designed CNSR improved postures noticeably and provided comfort for workers.
