测定材料的缓冲防震性能

Measuring vibration buffering characteristics of materials

利用力学、机械传感器研究了不同缓冲材料与其他物体碰撞过程中瞬时作用力及其与碰撞初速度之间的关系,得到了材料的缓冲防震性能的动态变化曲线,并通过改变同种材料的厚度,发现该材料对缓冲作用的不同响应,并得到了一定材料在防震中的最佳缓冲厚度.

The relations between instantaneous force and collision initial-speed of vibration buffering materials in collision process have been studied by using PASCO mechanical sensor package, and dynamic buffering curves is obtained. It is found that one kind of materials with different thickness has different buffering responds, an optimum thickness for a given buffering material in a certain shock circumstance can be obtained, which is of great importance in practice.
