【摘要】 针对MARC软件不能够直接分析物体在移动载荷作用下的应力和应变的问题,对MARC软件进行了二次开发。以井盖受移动载荷为例,采用MARC二次开发功能编写移动载荷子程序,分别分析球墨铸铁井盖和玻璃纤维增强树脂基复合材料井盖在高速、低速和加速情况下的变形和等效应力。分析结果对井盖的设计具有重要意义,对MARC软件的二次开发具有参考价值。更多还原

【Abstract】 MARC can’t analyze the stress and strain of an object under moving load,so it is necessary to redevelop MARC.Taking the well cover under moving load as example,MSC.MARC’s redeveloping function is used to program moving load subroutines.The displacements and equivalent stresses of well covers made of ductile iron or glass-fiber reinforced matrix composite at high speed,low speed and acceleration are analyzed respectively.The results have crucial meaning on optimized design of well cover and have reference value on the redevelopment of MARC software.更多还原
