Finite element model for evaluating pressure distribution of men's basic pattern on upper body

The finite element model was established to digitally evaluate the pressure when wearing men's basic pattern. The 3-D body measuring technology was adopted to acquire the point cloud data of men's basic pattern and the upper body. The assembly model of human body and man's basic pattern was established by reverse engineering software. Mesh generation, contact mechanics model of human body and basic pattern, and simulation calculation were in the finite element software. The simulation results show that the distribution of prssure and displacement between the base pattern and human body is obtained. And analyzing the pressure distribution can make conclusions that pressure value of middle shoulder is 2.102 - 4.134 kPa, pressure values of breast and back are 0 - 1.101 kPa, and pressure values of shoulder and neck point and shoulder point are 0 - 2.012 kPa. By pressure test, pressure value of middle shoulder is 3.14 - 3.20 kPa, pressure value of breast is 0.73 - 0.81 kPa, pressure value of shoulder and neck point is 0.54 - 0.61 kPa, pressure value of shoulder is 1.19 - 1.23 kPa, pressure value of back is 0.61 - 0.75 kPa. This illustrates that the model is available, and the result is correct and effective.
