远离碰撞烦恼：新型防撞产品(英文)
Taking the Worry Out of Collisions - The Park-Kwik Example

一直以来，停车库的防撞保护有两种方法。一种最普通的方法是使用钢结构，通常角钢附于方形混凝土柱周边，或者是将钢柱安置在物体周围。这种方法可以保护停车库，却不能避免车辆刮痕或凹陷等问题，而且在一些情况下，使本来就很紧凑的空间更加拥挤。
另一种方法是在立柱上和拐角处裹上软材料。橡胶已经被应用了，但它应用的时间并不长，因为橡胶材料容易吸附沙粒和灰尘，不能有效防止刮痕。也有很多停车库在立柱上裹上地毯，但减少刮痕的同时并不能成功防止灰尘，不利于保护建筑物结构的完整性。
最近一种吸收碰撞能量的塑模泡沫产品很受欢迎，它的使用是一种新方法。该品不同于橡胶和布料防撞产品，这些精心设计的塑胶泡沫产品在车辆碰撞时可以同时保护车库和车辆。

Historically, there have been two approaches to dealing with collision protection in parking structures.The most common approach has been to use metal structures usually made of steel. Often,steel angle iron is attached to square concrete columns.Other applications use steel bollards placed around objects to prevent collisions.These metal devices can help protect structures from collision from collision impacts.However,these metal protective devices do nothing to prevent scratches or dents on the vehicles themselves,and in some instances the space that they take up makes tight spaces even tighter.
Another approach has been to wrap some type of soft material around columns and corners in hopes of precluding scratches on cars as they navigate in tight spaces.Rubber has been used,but its success has often been short-lived because rubber materials tend to capture grit and dirt and lose their scratch-prevention potential.Another common homegrown solution has been to wrap carpet around columns.While such homegrown solutions may lessen scratches,they are less successful preventing dents and do virrually nothing to protect the structural integrity of the building.
A new third approach that is now gaining in popularity is the strategic use of energy absorbing molded foam products. Ulike the haphazard jerryrigged rubber or cloth protectors that some garages have used in the past,these highly engineered plastic foam energy absorbers are able to simultaneously protect structures and vehicles during collisions.
