锤片式粉碎机以其高效、廉价、适用性强等特点，在粮食、食品及医药等行业受到广泛应用。
Because of high productivity, low price and good applicability, hammer mill is widely used in many industries, such as grain and foodstuff processing industries, pharmacy industry etc.
采用动力接触有限元法分析强夯中夯锤对地基土的冲击碰撞过程，建立动接触力与速度之间的接触关系式。
Uses dynamic contact FEM to analyze impact and collision of hammer to foundation soil in the dynamic compaction, establishes the contact relation between dynamic contact force and speed.
在设计强夯加固地基工艺时，应考虑到“极限影响范围”的存在，而该影响范围仅与夯锤底面的尺寸有关。
The existence of "the ultimate scope of influence" should be taken into account when designing the process of reinforcing a ground by the dynamic consolidation.
