大型铸铁夯锤受力分析及破坏原因

Mechanical Analysis and Destruction Reason of the Large Size Cast Iron Rammer

采用有限元法对铸铁夯锤进行了受力计算，并对其在使用中的开裂破坏进行了分析。同时，考虑到铸铁材料的拉压不同弹性模量性，计算了不同模量比对夯锤应力的影响。对夯击接触时间、起落高度、地基硬物等因素也进行了探讨。

Mechanical calculation of cast iron rammer was made by using the finite element method and the cracking destruction was analyzed Considering the bimodulus of the cast iron the authors also analyzed the influence of the bimodulus Contacting time, rising and falling altitude and ground strong bodies were also discussed
