Mechanical calculations and simulations

Strength, stress and strain

Analytical calculations are foundational in mechanical engineering and represent a significant portion of the analysis-hours. This is complemented by FEA simulations and Python modeling.

Linear stress simulation

The figure on the right shows an example of an analytical calculation of stress in a conical spring and a linear stress simulation with non-linear contact simulation of a clamp-assembly for a highly pre-tensioned knife.

FEA analysis

These figures provides an illustration of the range of sizes of components on which Huygens Engineers performs work. The illustration includes an FEA analysis of a sizeable ground frame design (20 m in size) for a water turbine and, on the other side of the size-spectrum, an FEA analysis of a sensor body (20 mm in size) with a plate thickness of 1/10th mm.

Deformation analysis

For hyper-elastic and visco-elastic materials, a linear approximation of deformation is often inadequate. The video shows a large deformation (non-linear) analysis of a hyper-elastic material assembly
