Narrow gaps are present in rotating and reciprocating machinery such as turbines, compressors, pistons, and gear pumps. These narrow gaps are often essential for the operation of the machinery, as leakage of the working fluid through the narrow gap provides...
MET S.p.A. is a leading sports helmet manufacturer based in Talamona, Italy. Engineers at MET have used ADINA successfully to analyze their new helmet design. Depicted in the above animation are the stress contours of the helmet in their simulation...
Shield tunneling using a large tunnel boring machine (TBM) is widely used to construct underground tunnels for subways. During tunneling, the soil strata substance is pressed, crushed, and removed by the TBM boring head. The shields, which are pushed along...
The below animation depicts an axisymmetric model of a mono-tube gas shock absorber, with its schematic beside it. The piston inside the casing pushes its way through the oil (the hydraulic fluid which in reality is a mixture of oil...
ADINA 8.1 has several enhancements to its cyclic symmetry analysis capabilities. The sparse and iterative solvers can now be used to solve cyclic problems. The primary cyclic component is no longer required to be aligned with the X-Y plane, and...
In ADINA v. 9.0, we introduced a new graphics engine that enables fast visualization and manipulation of large models in the ADINA User Interface (AUI). Since then, we have continued to make improvements so that FGM supports many more capabilities...
A new powerful stiffness matrix stabilization feature will be present in ADINA 8.2 to stabilize static analyses in the presence of physical rigid body modes. The new stabilization technique can be used with or without the modeling features already available...
This animation shows unsteady flow in chambers connected by valves and a piston. The left chamber has an inlet and the right chamber has an outlet. As the piston moves down, the left valve opens, the right valve closes, and...
