According to the controlled shear rate (CSR) test, the shear stiffening gel (SSG) exhibited viscoelastic behavior, which can be fully described by the general Maxwell model. A specific analytical model was established to identify the material parameters automatically based on simulated annealing (SA) optimization. Besides, according to the CSR tests under different temperatures, the influence of temperature and strain rate on the mechanical behavior of SSG was assumed to be decoupled. And an applicable engineering relation was introduced for parameter adjustment of the Maxwell model near room temperature. The reliability of the material parameters was verified through the results comparison of the low-speed impact tests of SSG and corresponding FE simulations.

Based on field analysis of the FE simulations, the mechanism of the stress dispersion ability of SSG was elaborated. A feasible design idea was introduced to fully utilize this property. In order to verify the effectiveness of the design idea, a series of egg impact tests were developed, conducted, and analyzed. And the protective idea proved helpful in fully invoking the stress dispersion potential of SSG assembly for impact protection and improving the lightweight design.

基于有限元模拟的现场分析，阐述了SSG应力分散能力的机理。引入了一个可行的设计思路来充分利用这一特性。为了验证设计理念的有效性，开发、实施并分析了一系列鸡蛋冲击试验。事实证明，这种保护思想有助于充分发挥SSG总成的应力分散潜力进行冲击保护，并改进轻量化设计。
