Abstract

Abstract This study is aimed at investigating the effect of vibration on health and comfort in tractors with water tankers. The vibration was measured on the floor, seat pan, and backrest of the tractor at different speeds and water levels to optimize for low spinal load in terms of static compressive dose (Sed(8)) and comfort reaction (CR). The experiments were designed using the Taguchi Method and the Response Surface method, and the parameters were optimized using the desirability approach. Models developed to predict Sed(8) and CR showed a significant effect of speed and water level on Sed(8) and CR. The mean Sed(8) exceeded the limits of ISO 2631-5, indicating the probability of adverse health effects. The mean CR indicated uncomfortable exposure based on ISO 2631-1. The optimum ride levels were found at a speed of 8.4 m/s and water level of 3000 L. A confirmatory experiment substantiated the optimum conditions, with output lies within the 95% confidence interval of the predicted responses.

水车运行下牵引车行驶工况建模与优化

摘要本研究旨在探讨振动对水车牵引车健康和舒适性的影响。在不同速度和水位下，对拖拉机的地板、座椅底板和靠背进行振动测量，以优化低脊柱负荷的静态压缩剂量(Sed(8))和舒适反应(CR)。实验采用田口法和响应面法进行设计，并采用可取性法对实验参数进行优化。用于预测Sed(8)和CR的模型显示，速度和水位对Sed(8)和CR有显著影响，平均Sed(8)超过ISO 2631-5的限值，表明对健康产生不良影响的可能性。根据ISO 2631-1，平均CR表示不舒服的暴露。车速为8.4 m/s、水位为3000 L时的最佳行驶水平。验证性实验证实了最佳条件，输出在预测响应的95%置信区间内。
