Dynamic Simulation is the mathematical modeling of mechanical, thermal, fluid and acoustic systems undergoing time-varying behavior, such as harmonic, random or transient events. The simulation model can be based on explicit equations of motion, iterative methods, custom software, or commercial finite element analysis (FEA) simulation programs such as LS-DYNA, ABAQUS and ANSYS. We are experts in the use of simulation software to solve difficult engineering problems involving dynamic inputs and behavior. Complex events such as mechanical shock, impact, vibration, and transient thermal or flow events can be modeled and analyzed, leading to valuable insights that improve product performance and quality.
Cardiovascular Stent Dynamic Simulation
Modeling and Simulation is regularly used in biomedical and packaging industries to understand how complex systems will react under specified loading. For example, braided tubing and stent designs that may contain more than 500 unique fibers strand can be dynamically simulated using different materials and manufacturing methods to understand the performance characteristics of compression, tension, bending.
What is Finite Element Modeling?
Finite Element Modeling (FEM), also known as Finite Element Analysis (FEA), is a numerical method utilized to predict the performance of structural, thermal, fluid and electromagnetic systems. The method requires that the component being studied be broken into discrete elements, resulting in a finite element mesh. The simple equations that describe the individual elements' behavior are then assembled into a larger system of equations that models the entire problem. Depending on whether nonlinear effects are present the resulting system of equations is solved with a direct or iterative solver.
Accuracy of the results are dependent on many factors, including the refinement of the FE mesh, type of elements utilized, knowledge of the material model behavior, knowledge of the actual dynamic loading conditions, and ability to accurately model the physical system. Kinetic Vision's dynamic simulation services group utilizes multiple quality control systems, including QA checklists and peer review.
