甲壳虫外壳有着精巧复杂的构造。该文参照甲壳虫外壳中层间芯柱的微结构,设计出几个模型,利用ANSYS/LS-DYNA软件分析其耐撞性和抗冲击能力。然后改进原有模型的结构形态,使其更贴切甲壳虫外壳中小柱结构,缓冲吸能性能更好。将改进后的模型与圆管结构相对比,进行准静态和模拟冲击环境的分析。结果表明优化后的模型吸能量更多,压缩载荷更加稳定,抗冲击性能更好。可将其应用在结构防撞性和能量吸收装置中。 Beatles shell has a sophisticated structure. According to the microstructure of the middle column in Beatles shell, several models were designed and their crashworthiness and impact resistance were analyzed by ANSYS / LS-DYNA software. Then the structure of the original model is improved to make it more suitable for the small column structure of the shell of Beatles, which has better buffering energy absorption performance. The improved model is compared with the circular tube structure to analyze quasi-static and simulated impact environment. The results show that the optimized model has more energy absorption, more stable compressive load and better impact resistance. It can be used in structural crashworthiness and energy absorption devices.
