一种减小动体摩擦阻力的设计方案

技术领域

1)轮船、火车、飞机、火箭、导弹、航天器、汽车外表面摩擦阻力改进机械设计。2)输油、输气、输水管道内表面摩擦阻力改进机械设计。

背景技术

在技术领域1)中,当发生运动时,将出现与周围水体或空气的摩擦阻力,在技术领域2)中,当发生运动时,将出现管道摩擦阻力,为减小摩擦阻力,常用方法是增加表面光滑度和采用流线设计,在大面积表面或者高速运动时,摩擦阻力将成倍增长,能量损失非常大,在非常高速时,摩擦阻力转化的热能将使表面的温度升高。甚至损坏表面结构。

发明内容

在技术领域1)的外表面和技术领域2)的内表面铺设轮排或传动皮带的方式,将摩擦阻力由滑动摩擦方式转化为滚动摩擦方式,从而大大降低摩擦阻力。

具体实施方式

轮排或者传动皮带应铺满外表面或者内表面产生摩擦阻力的地方。

对轮排靠近固体表面侧采用半封闭方式,对传动皮带靠近固体表面侧采用全封闭的方式,动静结合处采用机械密封装置,即达到只露对侧部分与空气、水、油等流体接触并保持相对静止状态。

对表面接触气态物质如空气、天然气,装设轮排方式,对表面接触液态物质如水、油,装设传动皮带。

对轮排和传动皮带的大小,结构,材质,表面形状应根据实际应用场景确定。

对轮排和传动皮带铺设可以整体铺也可以拼装铺。

对轮排和传动皮带拼装前后结合处和前缘处采用导流片装置。

导流片装置应正好适合轮排或者传动皮带外侧边缘。
