| 英文摘要: |
| In order to check and compare different design results of hydraulic manifold block (HMB), an HMB assembly process simulation system is designed. In virtual 3D assembly environment, the parametric modeling method based on the feature element is adopted to describe the entities of the assembly unit. After the deep research on the assembly path planning algorithm, an optimal heuristic search algorithm based on A * is proposed to adapt the feature of HMB. At last, the simulation of HMB′s assembly is realized by using the technology of axis driving under spatial constraint. A demonstration example is also exhibited for verifying the proposed method and the experimental results demonstrate the practicability and effectiveness of the system. |
