High-protective-property variable-rigidity skiing helmet and design and preparation method thereof

Abstract

The invention discloses a high-protective-property variable-rigidity skiing helmet and a design and preparation method thereof, and belongs to the field of helmets. The method comprises the following steps: firstly, fusing a non-uniform curve reinforcement variable stiffness design technology into helmet design, and establishing a representation mode of a variable stiffness non-uniform curve rib model by utilizing a space variable condensation technology and a grid mapping technology to obtain a geometric model of a shell rib cluster; and parametric modeling of the curve ribs on the complex small-space special-shaped curved surface and collaborative design of the shapes and the layouts of the ribs are realized. Then, all components and proportions of materials used by the shell are determined through experimental testing, and injection molding process parameters are determined through mold flow analysis. And finally, a design scheme of the high-protection variable-stiffness skiing helmet is obtained. According to the method, parametric modeling of the curve ribs on the complex small-space special-shaped curved surface and collaborative design of the shapes and the layouts of the ribs can be realized; structural rigidity can be distributed in different areas according to needs, the design capacity of the helmet is remarkably improved, and the method is expected to be one of the most potential methods in helmet design.

AI Technical Summary

Benefits of technology

This patented innovator describes an improvement over existing designs for safety helmets by integrating certain technical features such as unevenly distributed bending stresses or varying degrees of flexibility within each section of the hat's surface area. These improvements result from advanced mathematical models that predict how well these sections will resist deformation under external forces during use without losing their effectiveness due to insufficient rigidity. Additionally, this new design allows for customization based upon specific needs rather than just being fixed beforehand. Overall, it provides better protection against impact damage while maintaining good comfort levels for users who wear them.
