Embodiment

[0058] (1) Acquisition of human calf point cloud data

[0059] A four-camera non-contact 3D human body laser scanner is used to collect basic human body data. During the test, the subjects were required to stand still on the 3D body scanner with bare legs, and try to keep the body in a static state during the measurement, so as to avoid the error caused by the shaking of the human body to the measurement results, so as to obtain more accurate measurement data. In this experiment, the three-dimensional human body scanning method was used to scan the entire lower limbs of the experimenter. The three-dimensional scanning image of the lower limbs of the human body is as follows Figure 5 shown.

[0060] (2) Preprocessing of human calf point cloud data

[0061] The scanned image of the 3D human lower limbs is intercepted in the reverse engineering software Geomagic Studio, and the point cloud data of the calf part from the ankle to the knee is selected for analysis and research. ...

Abstract

The invention discloses a method for forecasting clothing pressure distribution of human shanks. The method includes the steps: firstly, selecting point cloud data of the shanks from ankles to knees after acquiring the point cloud data of human lower limbs, preprocessing the point cloud data of the human shanks to obtain surface models of the human shanks, and building three-dimensional solid models and finite element models of the human shanks according to the surface models of the human shanks; secondly, sleeving fabrics on the shanks of persons to be tested, and directly applying pressure values of ten test points serving as loads into the finite element models to solve and obtain equivalent stress diagrams of various positions of the shanks of the persons to be tested after different pressure values of the ten test points on the shanks of the persons to be tested are obtained by the aid of a clothing pressure tester. In the finite element models of the human shanks, the elasticity modulus of skins is 150kPa, and the Poisson ratio of the skins is 0.46; the elasticity modulus of soft tissues is 60kPa, and the Poisson ratio of the soft tissues is 0.49; the elasticity modulus of skeletons is 7300MPa, and the Poisson ratio of the skeletons is 0.3.

Description

technical field [0001] The invention relates to the field of textiles, and more specifically relates to a method for predicting the pressure distribution of a human body's lower leg on clothing. Background technique [0002] Clothing pressure comfort is a very important factor affecting its overall comfort, and it is also an important index for evaluating clothing comfort. Clothing pressure refers to the force generated by the clothing acting vertically on the human body. Clothing pressure that is too large or too small does not meet the physiological requirements of the human body. If the pressure is too small, it is not conducive to the improvement of human body protection and exercise efficiency, and it does not conform to the aesthetic concept; if the pressure is too high, it will cause human fatigue, affect the human body's breathing, pulse and blood circulation, and seriously damage the health of the body. Appropriate clothing pressure has positive effects on body sh...
