Simulation validation is essential to confirm the accuracy of modeling and simulation results, and is often difficult for transient events such as shock, vibration and impact. Kinetic Vision is equipped with the latest technologies to test product dynamic performance and tune simulation models to match real-world performance. Using multiple sensors and hi-speed video, precise physical data is collected and post-processed. By validating simulation models, users can gain valuable insights into how best to utilize computer tools to represent real-world product performance.
Drop Test Simulation and High Speed Video Validation
In this example of simulation validation, high speed video of various drop tests of extrusion blow molded HDPE containers were captured and used to validate Fluid Structure Interaction (FSI) finite element models. The FSI models simulated various tests that the package needed to pass including: drop test, top load, pressure, and shipping. Validated models were the leveraged to optimize bottle weight, wall thickness, and material selection. Learn more about Finite Element Modeling.
Kinetic Vision's high speed video capabilities include 16 mm, 22 mm and 35 mm lenses and capture rates up to 24,000 frames per second. Video is directly captured to a personal or laptop computer which mobile applications and in-field frame-by-frame evaluation and editing.
Simulation validation creates the ground truth to enable modeling and simulation to accurately drive product development. In addition, it also encourages bidirectional feedback between M&S staff and test technicians, leveraging the knowledge gained by both. The result: a better understanding of your product or system performance, both physically and analytically.
Material Model Development and Validation
Material model development and validation is the process of understanding simulation material models and is a prerequisite for accurate simulation output and results conclusions. Our finite element analysis validation team is well versed with the development and implementation of complex FEA material models such as plastics, composites, and fabrics, and these models can be corroborated through testing in our in-house lab. Our Software + Solutions group can also develop custom user-defined material models when needed.
The Kinetic Vision Materials and Component Test Lab includes electric-driven dynamic tensile and compression testing with environmental chamber for calculation of material mechanical and thermal properties. Drop, impact, vibration and other transient events can be studied using our in-house high speed video capture system. In addition to standard tension/compression testing, 3D CT Scanning allows for visualization and measurement of macro and microscopic parts, part features and components, even while they are functioning.
