摘　　要：穿戴运动文胸可减少乳房位移,缓解乳房疼痛并保护乳房。已有研究证明文胸的不同部件具有不同的减振机理。为了能有效控制由个体差异和实验动作等因素引起的实验结果不稳定性,进一步探究运动文胸各部件的减振机制,文章首先自主制备了30件运动文胸,然后使用基于3D打印技术的运动假人模型替代真人实验,并对受试者进行了统一,最后通过动作捕捉设备监测运动假人穿戴不同运动文胸时的减振效果。采集5个不同位置处的乳房位移,评估其竖直方向的位移数据。通过系统地研究各部件的减振机制,为运动文胸的设计和材料选择提供建议。结果表明,在生产商制作和消费者选择运动文胸时,罩杯建议选用弹性模量较大的材料和高度较高的罩杯,肩带建议选用弹性模量较大的材料和长度较短的肩带,底围建议选择涤纶材料和围度较小的底围。The breasts are mainly composed of fat,mammary glands,and connective tissues.Due to the lack of support from bones and muscles inside,the suspensory ligaments are the most load-bearing parts of the breast.During exercise,ligament tissues are stretched and tightened.Over time,this can lead to breast droop or relaxation and may even result in breast diseases such as breast cancer.Wearing sports bras can reduce breast displacement,alleviate breast pain,and protect the breasts.Sports bras are mainly composed of three components:shoulder straps,cups,and underbands.Previous studies have shown that different components of bras exhibit varying vibration reduction mechanisms.However,the sports bras used in previous experiments were sourced from the market,making their structure,size,and material difficult to control.The recruited experimental subjects were non-professional athletes who exhibited significant individual differences in movements such as jumping and running.To effectively control the instability of experimental results caused by individual differences and variations in movements,and further explore the vibration reduction mechanism of various components of sports bras,this study first independently prepared 30 sports bras to control various parameters of the cups,shoulder straps,and underbands.Then,a manikin based on three-dimensional printing technology was used instead of human subjects to standardize the experiments.This approach aimed to reduce experimental errors caused by individual differences.Motion capture devices were used to monitor the vibration reduction effect of different sports bras worn by the manikin.The vertical displacement data were evaluated by collecting breast displacement data at five different positions.Finally,a significant analysis was conducted on the vertical displacement of breasts under different breast support conditions.The breast displacement reduction rate was used as an indicator to evaluate the vibration reduction effect of different component parameters of the bra.This a
