#i说说# 弓的变形能让利箭划破长空,滑靴的弹性形变又有怎样的玄机暗藏呢?我们先来看看Andrew Schenk是怎么说的:
The EHD(Elasto-Hydrodynamic) model rotated the slipper so the trailing edge is either converging or parallel to the swashplate. This allows pressures to build on the trailing edge while lifting the leading edge so the wedge effect from the deformation is less pronounced. The net effect of this action is a balance of pressure between the leading and trailing surfaces which in turn lifts the slipper slightly away from the swashplate.
—— Andrew Schenk
i小编班门弄斧来稍做解读:滑靴高速运行时,底面承受着高压,那变形自然再所难免。而这个支撑面的形变却带来了一个福利——和斜盘表面形成了楔形油膜。Leading edge侧(相当于车头)的楔形油膜符合动压支撑力产生的条件,而Trailing edge侧(相当于车尾)的却不行。这样一来,滑靴会略微朝着trailing edge侧倾覆来达到平衡。看似微米级的变形微乎其微,但对滑靴的良好工作却至关重要。滑靴不能好好工作,泵还怎能愉快的玩耍?
