Learn how to perform dynamic analysis using SOLIDWORKS Simulation. The course starts by covering dynamics theory and normal modes analysis. Dynamic analysis concepts are covered, including damping, mass participation, modal methods, and direct methods. Next, transient analysis is explored, including modal transient response, direct transient response, and base motion in dynamic response. Then, frequency response analysis, followed by how to interpret results.
In distinct contrast to the three FEA studies above, Lee et al. [19] performed dynamic, large-displacement analyses with hyperelastic materials which captured the mechanical interaction between the pacifier and the palate and calculated resulting stresses, strains, deformation, contact areas, and contact forces/pressures. Palatal interaction due to pacifier distortion from peristalsis and intraoral pressure during NNS was quantitatively characterized and evaluated in their analysis process. Alternatively, another study [20] reported on an image-processing technique based on anthropometric and physical parameter correlations to describe and evaluate interaction of a pacifier with the palate.

The aim of this study is to use the dynamic, nonlinear finite element analysis process of Lee et al. to evaluate the mechanical behavior of conventional and orthodontic pacifiers (identified by brand and size) positioned in age-specific palatal models with respect to both contact area and force when subjected to tongue function and intraoral pressure related to NNS.

A dynamic model was de.eloped. Due to the complexity of its geometry, tetrahedral elements were used for all parts. The approximated global sizes of the elements (intern-nodal spacing) were determined after a mesh sensitivity analysis and defined as 5 mm for the residual limb and 3 mm for the bone and the socket. The number of elements varied between approximately 300.000 and 480.000, depending on the size of the residual limb.
The explicit dynamic analysis procedure in ABAQUS was used for the gait cycle. Damping was calculated using the default bulk viscosity values, mass scaling was modified until the model converged, and incrementation time was set as automatic.
