Agricultural products, components for most of the complex model, and finite element analysis of high cost, single enterprise finite element analysis ability is weak. In order to solve this problem, it proposed a cloud based on agricultural products of finite element numerical simulation analysis system. Cloud computing platform consists of three layers, using parametric modeling, local engineers through the cloud computing resource pool of available parame-ter modeling of the interface, which can complete the agricultural product modeling. The built model can be directly through the software interface to import to the cloud layer analysis, through iterative calculation to cloud computing virtual simulation results, the presentation layer in form of images or curve show. To test the performance of the platform, the test results show that based on cloud computing finite element of agricultural digital analysis system can effectively com-plete parametric modeling, finite element simulation and calculation results, which can provide the support for the sharing and cooperative computing services for enterprises in the alliance.%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。
