Mechanical Property Analysis of Piling Mast for Walking Type Continuous Flight Auger Machine ZKL800BD

对ZKL80 0BD步履式长螺旋钻机折叠式步履桩架主体结构进行力学性能分析 ,根据该折叠式步履桩架结构实际特点 ,将折叠式步履桩架立柱进行有限元离散 ,利用有限元方法 ,研究其在起架时的强度、稳定性及变形情况 ,经过多种方案下的强度、稳定性和变形验算 ,满足了设计要求 。

Mechanical property of piling mast for folding type walking continuous flight auger machine ZKL800BD is analyzed.If uses finite elements method to make the piling mast discrete according to the feature of piling structure.The writer studies its strength,stability and deformation during piling lifting.It meets the design requirement through checking the strength,stabilitye and deformation under many working conditions.So the result can be a reference to the folding type walking piling mast design.
