| description | The invention relates to a boundary dummy modeling method, a boundary dummy model and a seat comfort checking method. The boundary dummy modeling method comprises the following steps: S1, collecting the size of a Chinese human body to obtain sample size data; s2, dummy model parameters are designed, wherein principal part analysis is conducted on sample size data; establishing a sample confidence ellipse; confidence ellipse feature points are selected, and the point closest to the feature points in the scattered points is calculated to serve as a boundary dummy; and S3, designing a dummy driving posture: designing the dummy driving posture according to a to-be-checked seat model and the boundary dummy obtained in the step S2 to obtain a boundary dummy model for seat comfort check. According to the method, the boundary dummy model representing Chinese actual population signs can be screened out, the Chinese population sitting posture distribution result can be reflected more accurately, and a reference basis i |
