Reduce costs of product development Finite Element Analysis

Finite Element Analysis (FEA)/ Finite Element Method (FEM) simulation is one of Tech Invent’s key activities. This method is an effective tool to reduce expenses in connection with product development. Simulation is used to optimise products in relation to material selection, material consumption, weight (topology optimisation) and for strength calculations of both individual parts and complete constructions. Furthermore, the deduction of the natural frequencies and associated vibration situations may contribute to creating safety and optimum functionality in mechanical systems. Thermal simulations may optimise energy solutions by, for example, knowing the solution’s internal and external utilisation of the heat flow. Typical we use simulation programs such as:

• ANSYS
• SOLIDWORKS Simulation Professional
• Pro/MECHANICA
• Nastran

A FEM simulation can be optimized to calculate more precisely when using measuring equipment. See more about this under the description of our test and measurement equipment.

You can always expect us to meet high requirements for reporting, documentation and compliance with relevant quality procedures. Our engineers have competencies within the following concepts:

• Finite Element Analysis (FEM-simulation)
• Strength studies and verification (FEA)
• Deformation studies
• Collision simulation
• Topology optimisation with respect to materials, material usage, weight and geometry
• Strength calculation of anything from individual items to large structures
• Dynamic fatigue calculation and life calculation, e.g of bolts and welds
• Linear and nonlinear stress analysis
• Modal analysis, which is the calculation of natural frequencies of different orders and corresponding vibration situations
• Thermal simulation, which is used in cooling calculations when mapping heat distribution
• Collision simulation where the durability of items is analysed, e.g. by drop testing
• Large deformations (explicit simulation)
