The invention provides a kangaroo leg imitating graded buffering seat, which is applied to the technical field of buffering seats for ships and warships, and is characterized by comprising a seat and a buffering system, the buffering system comprises a bionic buffering mechanism which is arranged below the seat and is used for coping with low-speed impact and an impact-resistant base which is arranged below the bionic buffering mechanism and is used for coping with medium-speed and high-speed impact; the anti-impact base is fixedly mounted on a ship deck; under low-speed impact, only the bionic buffer mechanism absorbs energy under the working condition of low-speed impact; under medium and high-speed impact, most of energy under medium and high-speed impact working conditions is absorbed by the impact-resistant base, and then residual energy is absorbed by the bionic buffer mechanism; the beneficial effects of the invention are that energy absorption can be carried out more scientifically based on bionics design; based on the gradient energy absorption theory, graded energy absorption of the buffer seat is achieved through the rigidity difference between all the structures, the energy absorption range is expanded, and the safety of passengers is effectively protected. The structure is simple, and replacement and maintenance are convenient.
本发明提供一种仿袋鼠腿部的分级缓冲座椅,应用在舰船用缓冲座椅技术领域,其技术方案要点是:包括座椅和缓冲系统;缓冲系统包括设置在座椅下方、用于应对低速冲击的仿生缓冲机构以及设置在仿生缓冲机构下方、用于应对中、高速冲击的抗冲击底座;抗冲击底座固定安装在舰船甲板上;在低速冲击下,仅由仿生缓冲机构吸收低速冲击工况下的能量;在中、高速冲击下,先由抗冲击底座吸收中、高速冲击工况下的大部分能量后,再由仿生缓冲机构吸收剩余能量;具有的技术效果是:基于仿生学设计,更科学的进行能量吸收;基于梯度吸能理论,通过各个结构间的刚度差异,实现缓冲座椅的分级吸能,扩大吸能范围,有效保护乘员安全;结构简单、便于更换和维修。
