US Cellular car tyres really are not afraid to spend it fried

我们经We often see in movies like this picture: The police chase criminals, police are often criminals shot off the hook and out of control, Happy criminals away. And in your heart, off-road capability superior off-road vehicle who is it?
 
Hummer is the Jeep Wrangler, Toyota Prado, Land Rover Defender, Mitsubishi Pajero, or 3.6 million worth of George Patton SUV? Even if your SUV off-road capability is really super, imagine this everywhere in Iraq are likely to step on a bomb the place, you will be able to ensure safe and sound right?
 
No matter how good the horse is out of the legs and feet, the traditional flat tyres or limited protection, or is costly. Polymer Research Center, Madison, Wisconsin, is quite the fight, not afraid of fried developed a tyre, of course, this is not afraid of bomb explosions just afraid of a certain degree.
 
 
This bionic honeycomb structure tyre, which includes tyre and solid cellular matrix, in fact, the heart of a rubber tyre production, through the "interference fit" tight hoop cellular matrix in the periphery; and a cellular matrix comprising an outer ring, the inner circle a columnar honeycomb structure of the ring and disposed between the outer ring and the inner ring, the cross-sectional structure of such a honeycomb hexagonal columnar shape.
 
 
 
Is the so-called principle of bionics, the hexagonal honeycomb structure of the support to each other, relying on mechanical configuration provides the ability to maintain shape, relying on an elastic deformation of materials to provide buffer capacity, to reduce vibration and improve wheel strength. Use structural design while maintaining a certain advantage to maximize damping performance improved wheel strength. On both noise suppression and tyre friction heat is also more favorable than ordinary tyres. Military purposes, cellular polymer molding tyres inflated tyres are safer than ordinary in the explosion, even shot will not tyre, and is suitable for use in such a large temperature difference between the desert regions, high structural strength of the wheel, resistant deformation, not inflated, easy to maintain.常在电影中看到这样的画面:警察追罪犯时,警车常被罪犯一枪打爆而失控,罪犯逍遥而去。而在你心中,越野能力超强的越野车型是谁呢?
 
是悍马,是吉普牧马人,是丰田普拉多,是路虎卫士,是三菱帕杰罗,或是价值360万的乔治巴顿越野车?就算你的越野车越野能力真的超强,设想一下,在伊拉克这种随处都可能踩到炸弹的地方,你就能保证安全无恙吗?
 
再好的马没了腿脚也不行,传统的防爆轮胎要么防护能力有限,要么就是成本高昂。美国威斯康辛州麦迪逊的聚合物研究中心也是蛮拼的,研制出了一种不怕炸的轮胎,当然这种不怕炸只是不怕一定程度的爆炸。
 
 
 
这种仿生学蜂窝结构的轮胎,它包括实心外胎与蜂窝胎体,其实心外胎由橡胶制作,通过“过盈配合”紧箍在蜂窝胎体外围;而蜂窝胎体包括外圆环、内圆环以及设于外圆环与内圆环之间的蜂窝柱状结构,这种蜂窝柱状结构的截面为六边形形状。
 
 
 
而所谓的仿生学原理就是,将蜂窝的六边形结构互相支撑,依靠机械构造提供形状维持能力,依靠构型材料的弹性提供变形缓冲能力,达到降低振动、提高车轮强度的作用。利用结构设计的优势在保持一定减震性能的同时最大化地提高车轮强度。同时在噪音抑制和轮胎摩擦发热量上也比普通轮胎更为优越。在军事用途上,蜂窝状聚合物成型轮胎比普通充气轮胎在爆炸时更安全,即使中弹也不会爆胎,而且适合在沙漠这种温差大的地区使用,车轮结构强度很高,可抗变形,不用充气,便于维护。
