Blood is pumped from the heart, a muscular organ, to various body organs via blood arteries. The aim of this paper is to create a temporary device, such as a pump, for individuals with cardiac diseases for whom survival without a transplant is unfeasible. Until a donor heart becomes available, the patient may have ample time with these makeshift devices. This paper uses engineering principles to explore the idea of an artificial heart. Using SOLIDWORKS 18 and ANSYS 21, numerical simulation and examination of the artificial heart were carried out. A Multiphysics static structural model and fluent fluid flow (CFD) analytical techniques were utilized to ascertain the dynamic response and impacts of pressure. SOLIDWORKS was utilized to model the 3D geometries, and ANSYS Design Modeler was used to import the geometries for preprocessing. The solver used throughout the study is ANSYS FLUENT, a tool used to analyze fluid flow troubles, known as Computational Fluid Dynamics (CFD). Next is mesh generation, which means discretization of the domain to solve governing equations at each cell and later specify the boundary zones to apply boundary conditions for this paper. The simulation results showed that at maximum levels of absolute pressure in air pressurized chambers, the performance of the heart remained secure and suitable for comfortable conditions.
Differential Evolution (DE) is an informative and direct approach to optimization with limited control parameters. This paper presents a multi-position and orientation analysis of a Spatial Parallel Manipulator considering the influence of physical constraints, such as limb lengths and spherical joint motion. The synthesis process primarily involves determining the scopes of the permanent base and movable platform relative to the axes of the revolute joints, enabling the moving platform to traverse a predetermined range of positions. The dimensions of the moving platform and fixed base are determined by considering restrictions on joint motion to design the parallel manipulator using the DE algorithm method. The synthesis procedure is illustrated with a numerical example involving eight positions.
