Alcove’s Structural Analysis Methodology
We carry out Finite Element Analyses on products or concepts to validate them before the manufacture, determining safety and performance levels with respect to strength, cost, manufacturability, life etc., evaluating multiple “what if” scenarios. This process can effectively be used to optimize the design, lower risks during manufacturing as well as the probability of failure during the usable life cycle of the product.
Structural analyses are carried out to find a structure’s response to a load. We ensure that through the pre-processing, Stress Analysis and post-processing stages, the model reflects reality, and that results are captured and analyzed from a design and functionality context. Design sensitivity analyses are carried out to analyze interdependencies and probabilistic analyses are performed to ensure that the probability of failure is low.
Modal Analysis Methodologies To carry out modal analyses, it is important to accurately model stiffness, mass, damping and mass distribution to reflect the structure’s modal behaviour. Our experience in experimental modal analysis and vibration testing of components help us understand the behaviour of joints, contact conditions and other behaviour to model behaviour of structures. Analyses of mode shapes and natural frequencies are carried out and subjected to quality checks to ensure correctness of modelling.
If the structure experiences excitation at or near the resonance frequencies, the amplitude of vibration during oscillation or rotation can be large and can pose danger to the product life and to people in the vicinity of the structure. In such cases, vibration Modal Analyses are conducted and suggestions are usually made to change the structure’s stiffness, mass or damping to:
- Control the amplitude during resonance to a minimum, or
- Shift the region of resonance to outside the region of intended use / excitation of the product
The Alcove CAD Design for Manufacture (DFM) Methodology
- Recognize customer goals
- Study product lines and production platforms
- Determine the product assembly
- Understand the manufacturing process
- Design for manufacturability with focus on symmetry, simple tooling and optimal achievable tolerances
- Adhere to manufacturing process guidelines
The design team in fact keeps DFM in mind when they start with the concept design, resulting in a better design and far easier manufacturing methods. If you are looking at manufacturing product lines that are increasingly complex, at reducing manufacturing costs, and achieving quicker throughput time, with no compromise on r quality, outsourcing DFM (Design for Manufacturing) services to Alcove can help you achieve your goals.
