A Study of Fine Denier Propylene Knitted Fabrics'''' Wet Comfort-The Wet Comfort Studied by Subjective Wear Trial and Synthetic Dis-cussion

This paper is mainly concerned with the wet comfort of the fine denier propylene knitted garment. The subjec-tive sensation to these propylene garments is recorded in wear trial and analyzed. The relations among the normal objective test, the manikin test and the subjective wear test are discussed. The wicking height, the moisture re-sistance, the water holding ability, the moisture releas-ing and drying ability are recommended as the normal objective ways to evaluate fabric's wet comfort. At last, some principles on designing this type of fabrics are sug-gested .

Skin Sensitive Difference of Human Body Sections under Clothing-Smirnov Test of Skin Surface Temperatures'' Dynamic Changing

Skin sensitive difference of human body sections under clothing is the theoretic foundation of thermal insulation clothing design.By a new method of researching on clothing comfort perception,the skin temperature live changing procedure of human body sections affected by the same cold stimulation is inspected.Furthermore with the Smirnov test the skin temperatures dynamic changing patterns of main human body sections are obtained.     

Comfort of Light-weight Wool and Wool Blend Woven Fabrics

The comfort of the light-weight woven fabrics was investigated by conducting the wear trials under the controlled climatic conditions. The wear trial under the neutral environmental conditions showed that the lightweight wool and wool blend fabrics are generally less comfortable than the silk fabric, cotton poplin and polyester/cotton poplin fabrics tested in this study. The main shortcoming in terms of comfort for these lightweight wool fabrics is the prickle. Besides, the fabric softness was found to be a very important factor influencing the comfort of the clothing worn next to the skin.     

基于路面识别的非线性悬架系统自适应控制

针对非线性悬架系统,基于多目标布谷优化和路面识别算法,研究不同路面等级下悬架非线性系统特性,实现根据路面等级调整控制参数的目的.首先建立四分之一车辆模型,选取电流为优化变量,簧载质量加速度和轮胎动行程为优化目标;然后利用布谷优化算法求取不同路面下悬架最优参数,并利用路面识别方法得到当前路面等级,结合悬架性能需求实现悬架在不同路面下自适应调节.仿真结果表明:1)控制算法可根据不同路面情况自适应调整悬架参数,提高系统性能;2)相比于传统粒子群优化方法(PSO),基于布谷优化算法得到的控制电流能提供更为理想的悬架系统性能.
