“…But such options could be tedious and time consuming. An interesting tendency is the use of modern approaches, [4,5], in order to integrate the geometrical model with the FEA package. The optimisation process could be automated by use of the programming language Python.…”

The design of bimetal strips actuators is usually based on some approximate formulas. The cross section of the bimetal actuators is usually constant. In order to optimize the shape of the bimetal it is important to know the configuration of the deformation process in the entire body during real conditions. The paper presents a Finite Element Analysis of simple bimetal beam. There have been considered both thermical and mechanical loads acting on the bimetal actuator . The study focused on the distribution of stresses and the strain energy distribution in both longitudinal and transversal sections. Areas with smallest values and gradients for these parameters could be considered for material removal in order to reduce the volume and optimize the shape of the bimetal simple beam actuator.

“…The process of shape optimisation implies successive changes in CAD geometry model, based on the analysis of FEA simulations. This process could be significantly simplified by use of modern approaches, [4], in which the CAD model is integrated with the FEA model, by use of the Python language.…”

Bimetal actuators are frequently used in engineering applications. The literature for the design of bimetal actuators recommends only approximate analytical formulas for various bimetal structures, all with constant section on the entire length. No reference was found for bimetals with variable cross-section or bimetals shape optimization. Topology and shape optimization specialized software packages are not always an available or easy to use option. The paper presents a Finite Element Analysis, FEA, for a U-shaped bimetal with equal legs, considering both mechanical and thermal loads. FEA modeling aspects and some suggestions considering possible new shape modifications for this type of actuator are discussed.
