　　在Ansys、Pro/Mechanica、Cosmos环境下创建了一维阶梯杆的有限元模型，采用不同有限元算法计算出一维阶梯杆的应力、应变、位移。将真实结果与有限元软件得出的近似解进行求差，通过误差分析对这三种有限元算法在静力学分析方面的求解精度进行比较，以此来评估这三种算法在处理同一问题时的优劣性，为解决实际工程问题时选择一种合适的有限元算法提供参考和依据。

The finite element model of 1D bar is separately set up in Ansys,Pro/Mechanica and Cosmos software,the stress, strain and displacement of 1D bar are calculated by different finite element methods.The subtract is made between true results and approximations ,then the calculate accuracy of the three finite element methods about static analysis are compared by error analysis, the advantage of the three algorithms are evaluated based on that,and a basis and reference are offered to choose an appropriate algorithm when solves engineering problem.
