自动扶梯桁架的有限元分析
|
摘要
推导扶梯桁架的有限元理论,利用Pro/mechanica对扶梯桁架进行静态分析,研究其力学特性,计算在扶梯桁架承受最大工作载荷时桁架结构的最大内应力和最大挠度。根据材料的屈服强度与软件模拟的结果进行对比,得出材料是否符合满足强度和国标的要求。
Finite element method and application of escalator′s truss are deduced.By using Pro/Mechanica to carry out static analysis to the escalator′s truss so as to investigate its mechanical characteristics.The results of maximal internal stress and maximal flexibility were obtained when the truss structure withstands maximum operating load through calculation.After comparing the Material yield strength with the result obtained by software simulation,the material can be decided whether the strength and national standard requirements are met or not.
