Increasing Efficiency of the Engine Noise and Vibration Development Using Hierarchical Desktop Engineering Tool and Knowledge Base

Previously the authors devised a new engine noise and vibration (NV) development process using the hierarchical desktop engineering tool and the knowledge base. In this research the authors applied the new process to an engine development and verified its effectiveness. From the initial design stage before creating the fully assembled 3D drawings, the specifications of main components were concurrently investigated using three types of simple desktop tool (conceptual parts design review, 1D/2D simulation, and light 3D simulation) and the database accumulated in past developments and benchmark tests. This enabled to avoid that main components significantly deteriorated the NV performance, and also to reduce the time and effort required for multi-objective optimization using the large scale 3D simulation at the latter stage compared with the past. These results demonstrated that the new engine NV development process is effective for increasing the efficiency of engine development.
