摘　　要：自适应有限元法是一种以误差估计与自适应网格改进技术为核心,通过后验误差估计进行自动调整算法以改进求解过程的高效率、高可靠性的数值方法。简要介绍了自适应有限元法,并对实际工程中广泛应用的h-法与p-法进行了研究。以工程中的常用零件为算例,利用有限元分析软件SolidWorks Simulation进行了常规法、h-法与p-法的求解,根据最大合位移、最大等效应力与自由度数量的求解结果对各法的差异进行了分析对比,体现了自适应有限元法的特点,并对此法进行了前景展望。Adaptive FEM is a high efficient and reliable numerical method which can adjust algorithms automatically to improve the solving procedure. The key of it includes the error estimation, adaptive refinement techniques. The paper introduces adaptive FEM briefly and studies the h-method, p-method which widely used in engineering. The FEA software SolidWorks Simulation is used to solve an example by the general method, h-method and p-method respeceively. Bascd on the maximum displacement, von Mises stress and the maximum number of freedom degrees, differences among these methods are discussed. It is reflected the advantages of adaptive finitc clement method. This paper also presents the prospect of FEM.
