Abstract:

In order to provide reference for the delearn about Man's lower limb skin change rule during riding was analyzed. The contraction and relaxation of the mrscles of the legs caused a greater change in the surface of the skin, and six typical riding actions were selected, and the testers' right leg size data were measured by lineation-on body method to lbtain man's lower limb body surface data and the data change rule was nanlyzed. It is found that, the tensile deformation of the skin of all parts of the leg is complicated and varies considerably, with the wariation rate of -61.10% to110.82%. The skin deformation between the waist line and crotch line is significant, and the biggest one is the changes of the waist line, the hip line and the thigh contour line; in the longitudinal direction, the front crotch reduces the most, with the minimum value of -42.01%, and the decreasing trend gradually becomes smaller in the position of the outer side suture; the rest crotch increases the most with the maximum of 61.71%; and knee movement causes more complicated changes in the knee line and a greater impact on the body length.
