大型复杂机器的机架(例如大型模锻水压机)是由若干板、梁、杆、柱、壳和三维实体,通过机械联接的方式组合而成的。为了保证使用这类机械的工作精度,刚度是一个十分重要的指标。过去,复杂机器机架的刚度计算是十分粗糙的。随着我国电子计算机的应用和有限单元法的推广,才使得大型复杂机器的整机分析得以可能。目前国内流行的可用于大型机器整机分析的程序不多,且经费昴贵,对计算机的要求很高。因此,编制一个能用于整机机架
Large complex machine racks (such as large forging hydraulic press) is composed of a number of plates, beams, rods, columns, shells and three-dimensional solid, the combination of mechanical coupling. Stiffness is a very important indicator in order to guarantee the working accuracy of such machinery. In the past, the stiffness calculation for complex machine stands was very rough. With the popularization of the application of computer and finite element method in our country, it makes the whole machine analysis of large and complicated machines possible. At present, there are not many programs that are popular in the domestic market for the analysis of machine-wide large-scale machines, and are expensive in terms of expenses and have high demands on computers. Therefore, the preparation of a machine can be used for the rack
