[Abstract]:In order to solve the problem of computing expenses for digital analysis and simulation of modern agricultural machinery complex products, a digital simulation system platform for agricultural machinery products based on cloud computing is proposed, which adopts the three-tier architecture of cloud computing and the idea of service encapsulation. The functional requirements of the finite element analysis and simulation system are divided into services to provide the parallel collaborative computing function in the cloud environment for the finite element method. Using virtualization technology, the finite element design resources are managed centrally by cloud environment, and the flexibility of software delivery and the sharing of computing resources are realized. Taking the large deformation support structure of agricultural machinery components as an example, the model establishment, job management and data processing of the system are verified by examples. The simulation results show that the convergence accuracy and calculation efficiency of the parallel computing in cloud environment are greatly improved, and the structure of agricultural machinery components with large deformation can be calculated, and the sharing rate of resources is high. The digital and cooperative design of agricultural machinery components is realized.
