Evaluation of a knee-kicker bumper design for reducing knee morbidity among carpet layers

Carpet layers have a high prevalence of occupational knee morbidity. One of the main causes is that they need to frequently 'kick' the bumper on the rear end of the knee kicker with one knee when laying a carpet. Considering the bumper's marked effects on kicking force transmission and safety, this study aims to improve the design of the knee-kicker bumper by reducing the risk factors. An improved pendulum-type impact-testing platform was designed as an evaluative apparatus, with the impulse and the coefficient of restitution serving as evaluative criteria. The newly developed bumper has improved firmness from drilled blind holes and an increase in effective forward force of 15%-138%, which implies lower operational demands and a lighter knee burden (i.e., less kicking energy results in the same work efficiency), and a softer contact surface that enhances operating comfort. The newly designed kicker was positively reviewed by subjects.

Vacuum preloading combined electroosmotic strengthening of ultra-soft soil

To assess the effectiveness of vacuum preloading combined electroosmotic strengthening of ultra-soft soil and study the mechanism of the process, a comprehensive experimental investigation was performed. A laboratory test cell was designed and applied to evaluate the vacuum preloading combined electroosmosis. Several factors were taken into consideration, including the directions of the electroosmotic current and water induced by vacuum preloading and the replenishment of groundwater from the surrounding area. The results indicate that electroosmosis together with vacuum preloading improve the soil strength greatly, with an increase of approximately 60%, and reduce the water content of the soil on the basis of consolidation of vacuum preloading, howeve~ further settlement is not obvious with only 1.7 mm. The reinforcement effect of vacuum preloading combined electroosmosis is better than that of electroosmosis after vacuum preloading. Elemental analysis using X-ray fluorescence proves that the soil strengthening during electroosmotic period in this work is mainly caused by electroosmosis-induced electrochemical reactions, the concentrations of Al2O3 in the VPCEO region increase by 2.2%, 1.5%, and 0.9% at the anode, the midpoint between the electrodes, and the cathode, respectively.     

服装舒适性主观评价及主客观指标间的相关性研究

针对评估主观测试方法在服装舒适性上的应用,本文运用数理统计的方法,对涤纶、棉、涤/棉混纺面料服装在不同的气候条件下对其舒适性进行主观测试评价,并对其主要物理指标进行测试,同时运用回归分析对主观舒适性指标和客观测试指标进行了相关性分析,实验结果表明,主客观测试能够辨别出服装舒适性能的总体差异,并且对于服装舒适性趋势预测的呈现有所帮助。主客观测试结果具有一定的相贯性,而与服装舒适性主观感觉相关度最高的测试指标为水蒸汽传递速率、透气率、织物模量以及悬垂指数。主观测试方法可以很好的适用于热、冷环境下着装人体热湿舒适性的研究。
