摘要

背景:女性农业工人占印度农业劳动力总数的 37%:在印度,女性农业工人占农业劳动力总数的 37%,但大多数自走式机械都是为男性农业工人设计的:主要目的是确定经过人体工学改进的操作员工作场所对操作员各方面表现和舒适度的影响,包括操纵力、姿势和生理参数:实验在真实的现场条件下进行,采用全因子随机设计。12名女性操作员参与了研究,并对控制杆的操纵力、操作员姿势、心率和其他相关参数进行了测量:结果:经过人体工学改进的操作员工作场所干预措施显著降低了各种控制杆的操纵力、关节角度、工作心率(WHR)、耗氧量(OCR)、肌肉负荷和全身振动(WBV)加速度。在不同的操作条件下观察到了这些减少:研究结果表明,经过人体工学改良的操作员工作场所能有效提高操作员的舒适度,减少操作骑乘式自行机械时的身体负荷。它有助于提高操作员在野外条件下工作的安全性、舒适性和操作效率。方差分析和 MANOVA 分析证实,在使用人体工程学设计的操作员工作场所时,操作条件和发动机转速对测量参数有积极影响。

Development of ergo-refined operator's workplace and biophysically actual cost-benefit analysis of riding type self-propelled machines with special reference for female operators.

Background: Female agricultural workers contribute to 37% of the total agricultural workforce in India, however, most self-propelled machinery is designed for male agricultural workers.

Objective: The primary objective was to determine the impact of the ergo-refined operator's workplace on various aspects of operator performance and comfort, including actuating force, posture, and physiological parameters.

Methods: Experiments were carried out in real field conditions using a full factorial randomized design. Twelve female operators participated in the study, and measurements were taken for control lever actuating force, operator posture, heart rate, and other relevant parameters.

Results: The ergo-refined operator's workplace intervention resulted in significant reductions in actuating force for various control levers, angles of joints, working heart rate (WHR), oxygen consumption rate (OCR), muscle load, and whole-body vibration (WBV) acceleration. These reductions were observed under different operating conditions.

Conclusion: The findings suggest that the ergo-refined operator's workplace is effective in enhancing operator comfort and reducing physical strain during the operation of riding type self-propelled machines. It contributes to improved safety, comfort, and operational efficiency for operators working in field conditions. ANOVA and MANOVA analyses confirmed the positive impact of operating conditions and engine speed on the measured parameters when using the ergo-refined operator's workplace.

期刊介绍: WORK: A Journal of Prevention, Assessment & Rehabilitation is an interdisciplinary, international journal which publishes high quality peer-reviewed manuscripts covering the entire scope of the occupation of work. The journal''s subtitle has been deliberately laid out: The first goal is the prevention of illness, injury, and disability. When this goal is not achievable, the attention focuses on assessment to design client-centered intervention, rehabilitation, treatment, or controls that use scientific evidence to support best practice.
