【摘要】：农机产品的部件大部分为复杂模型,而有限元分析成本较高,单一企业的有限元分析能力较弱。为了解决这一难题,提出了一种基于云计算的有限元农机产品数字化仿真分析系统。云计算平台由3层组成,采用参数化建模方式,本地工程师通过云计算资源池提供的参数建模界面可以完成农机产品建模,建好的模型可以直接通过软件接口导入到云分析层,通过迭代计算得到云计算虚拟仿真结果,再由展示层以云图或者曲线的形式展现出来。对平台的性能进行了测试,结果表明:基于云计算的有限元农机数字化分析系统能有效地完成参数化建模、有限元仿真和计算结果的处理,可为联盟内企业提供共享和协同计算服务。
[Abstract]:The components of agricultural machinery products are mostly complex models, but the cost of finite element analysis is high, and the finite element analysis ability of single enterprise is weak.In order to solve this problem, a numerical simulation and analysis system of finite element agricultural machinery products based on cloud computing is proposed.The cloud computing platform is composed of three layers and adopts parameterized modeling method. Local engineers can model agricultural machinery products through the parametric modeling interface provided by cloud computing resource pool, and the built models can be directly imported into cloud analysis layer through software interface.The virtual simulation results of cloud computing are obtained by iterative computation, and then displayed by the display layer in the form of cloud map or curve.The performance of the platform is tested. The results show that the numerical finite element analysis system based on cloud computing can effectively complete the parameterized modeling, finite element simulation and the processing of calculation results.It can provide sharing and collaborative computing services for enterprises in the alliance.
