Strength and Durability Analysis Market DriversIn order to achieve the aim of reducing weight for better performance and lower fuel consumption, component engineering continues to approach the limits of strength and durability. For example, the crankshaft is a component that is subject to significant mechanical stress, therefore its design requires calculations that are as accurate and realistic as possible from the earliest concept stage. On account of the limited amount of data available at this early phase, simplified but reliable simulation models are essential. The use of numerical methods, supplementing pure analytical solutions, is becoming more critical and this requires semi-automated model generation for easy and fast creation of simulation models.
AVL ApproachThe main feature of the integrated solution within AVL EXCITE is its universal applicability which ranges from small one-cylinder engines to large diesel ship engines. With EXCITE Designer, simple analytic models can be created that can then be used as a basis for more detailed, numerical 3D models in the course of the analyses.
This integrated concept guarantees a complete development process that is time efficient, enabling programs to use common data, input menus and pre- and post-processing tools.
AVL EXCITE Strengths- Optimal solutions for all stages in the development process, engine sizes and configurations
- Diverse array of joint models depending on the application
- Accurate cranktrain analysis by considering the interaction of component elasticity and bearing oil film pressures, influences of inertia forced deformations and gyroscopic effects
- EHD bearings can be used for all crankshaft and conrod bearings for detailed analysis
- Complete crankshaft analysis workflow – automated model generation from CAD geometry (AutoSHAFT / Shaft Modeler), calculation of stress meshes (Fillet Modeler), calculation of stress with EXCITE FEA and strength evaluation with EXCITE Fatigue
Your Benefits- Transient engine run-up simulation assists in detecting all resonances, shortening the project time and developing designs closer to endurance limits
- Accurate dynamic loads and deformations for strength analysis of crankshafts and flywheels, main bearing walls, conrod, piston, engine mount brackets, timing drive and driveline components
- EXCITE FEA, an Abaqus®-based FE-solver and EXCITE Fatigue, an fe-safeTM-based fatigue strength analysis tool enables users to run FE tasks without needing to leave the EXCITE workspace
