VPDS is a company focused on Structural Analysis. Our specialty and extensive experience is in development and application of Flexbody Technologies and Tools. A Flexbody is another form of a structural analysis model. They are utilized in multibody tools and/or system simulation software programs. Many of our leading structural analysis capabilities come from Flexbody models coupled with system simulation models. In our experience and vision, system based analysis produces significant gains in knowledge, and creates the possibility to predict loads and stress on many structures.

System simulation tools are used to model machines that represent a particular product of interest (e.g. cars, trucks, tractors, recreational vehicles, mechanisms, satellites, exercise equipment, etc.). In addition to Flexbody structure models, many subsystems may be modeled within a system or machine model simulation (e.g. hydraulics, powertrain components, electrical controls, tire models, etc.). Because we have experience with system simulation, we also offer system performance analysis skills and capabilities.

We have listed many areas of focus which we offer development skills and application services. We look forward to the possibility of working with your company in one or more of these areas to provide solutions and help your company and products succeed. Feel free to contact us for more information, details and answers to potential questions.
