摘　　要：针对传统防滑链的固有缺陷,由章鱼吸盘受启发,运用仿生学原理和真空吸附原理,结合冰面防滑实际,初步构建了基于矩形布局规律的以圆锥型吸盘为仿生单元体的仿生随机轮胎布局模型,并运用Pro/E软件设计出仿生轮胎三维实体模型。最后,利用ANSYS软件对仿生轮胎实体模型进行有限元分析与仿真,从微观角度对吸盘式花纹进行了力学分析及有效吸附性能验证。仿真结果表明,吸盘式花纹的结构设计比较合理,抗拉、压等性能明显得到提高,且可以与冰面发生有效吸附,能确保轮胎的吸附防滑性能。In view of the inherent defects of traditional anti-skid chain, inspired by octopus suckers, with bionics principle and vacuum adsorption theory and combined with the ice surface anti-skid facts, a pre- liminary bionics random tire distribution model is founded based on rectangular layout rule with conical- shaped sucker for bionic unit and the bionic tire 3D solid model is designed by using Pro/E software. Fi- nally, ANSYS software is used to carry out the finite tity model; also, mechanical analysis and effective element analysis and simulation of the bionic tire en- adsorption performance verification are made of the sucker type pattern as viewed from the micro-angle. The simulation results indicate that the thread struc- tural design of the sucker type pattern is rather rational, and such performances as tension-resistance and compression-resistance are greatly improved so that the bionic tire can effectively adsorb4he ice surface and the tire adsorption and anti-skid performances can be guaranted.
