The inward displacement perpendicular to body surface produced by external pressure is an important index to evaluate pressure comfort and optimal design of tight clothing products. Because of the limited pressure exerted on the human body after wearing compression clothing, the corresponding displacement is generally small, and it is difficult to obtain an accurate displacement value of the human body using general methods. In this paper, we focused on the functional relationship between pressure and displacement when the human body was in the walking state after dressing in elastic pantyhose, and then the displacement data could be easily obtained using this method.

Through computerized tomography scanning, establishing of the waist cross-section, finite element simulation, and curve fitting, we finally obtained the functional relationship between the pressure/displacement ratio and angle when the body is dressed in four sample elastic pantyhose during the walking process in this study. In the formula, pressure data can be easily obtained through the pressure experiment, and the corresponding displacement value at any point of the human body can be calculated using the quadratic fitting curve equation. Results indicated that no matter what state the human body was in (static or dynamic) after wearing elastic pantyhose, the relationship between pressure and displacement at the corresponding point remains basically unchanged. That is to say, the relationship between pressure and displacement was basically not affected by the state of the human body when dressed in a tight garment. The conclusions provide an important reference for evaluating pressure comfort and optimizing clothing structure. This method is also applicable to other types of compression clothing.

由外部压力产生的垂直于身体表面的向内位移是评估压力舒适性和紧身服装产品最佳设计的重要指标。由于穿着压缩衣后施加在人体上的压力有限，因此相应的位移通常很小，并且难以使用常规方法获得准确的人体位移值。在本文中，我们着重研究了穿弹性连裤袜后人体处于行走状态时压力与位移之间的函数关系，然后可以使用这种方法轻松获得位移数据。

通过计算机断层扫描，腰部横截面的建立，有限元模拟和曲线拟合，我们最终获得了人体在行走过程中穿着四个样本弹性连裤袜时压力/位移比与角度之间的函数关系。这项研究。在该公式中，可以通过压力实验容易地获得压力数据，并且可以使用二次拟合曲线方程式来计算在人体的任何一点处的对应位移值。结果表明，无论穿着弹性连裤袜后人体处于什么状态（静态或动态），相应点的压力与位移之间的关系基本保持不变。也就是说，穿着紧身衣时，压力与位移之间的关系基本上不受人体状态的影响。结论为评估压力舒适度和优化衣着结构提供了重要参考。该方法也适用于其他类型的压力服。
