Academic experimental research requires flexible, customizable, easy to use yet powerful tools for developing and implementing new, innovative algorithms, methods, and systems for structural dynamics applications.
National Instruments offers a complete family of data acquisition, monitoring, and data-logging devices for desktop, portable, embedded, and networked research applications and systems. You can easily configure and program these devices using NI LabVIEW, a development environment and graphical programming language ideal for performing data acquisition, monitoring, and data-logging tasks, as well as for scientific computing and data visualization. Easily design, prototype, and implement new algorithms and mathematical models using a common set of tools that provide different levels of abstraction and models of computation within the same development environment.
The NI graphical system design approach for structural dynamics provides a unified platform that empowers you to integrate real-world signals with mathematical models and algorithms. It allows code reuse and takes advantage of new advances in computing and hardware acceleration technologies such as multicore processors, Graphical Programming Unit (GPU), and field-programmable gate arrays (FPGAs) for optimizing system performance in a way that outpaces traditional design methodologies. As a result, you can develop prototypes and proof-of-concepts (POC) in less time and with less effort, fewer errors, and lower total cost.
The LabVIEW graphical system design platform gives you the power to design and validate the design through real-world implementation with ease and the flexibility of its open, modular platform architecture.
2. Graphical System Design in Structural Dynamics
Academic research in structural dynamics focuses on the study of structures (concrete, mechanical, and so on) and their response under dynamic loading. This process typically involves three steps:
- Developing mathematical models that describe a physical system
- Analyzing the models to learn about their dynamic characteristics
- Creating a controller or damping mechanism to achieve certain dynamic characteristics (goals) under specific operating conditions and boundaries
You can use structural dynamics to find dynamic displacements, acceleration, and modal analysis.
Usually, each of those tasks requires different tools: one for modeling and simulating the structure and the controller or damping mechanism, one for prototyping the controller and the physical structure, and one for implementing the controller/damping mechanism in the field or laboratory. Both the prototyping and implementation (deployment) tasks require a tight integration with hardware (measuring, computing, processing), so that the controller you design can be tested with real-world signals under operating conditions that can resemble the real ones. Scientists and engineers usually want to have the flexibility to choose between using readily available, commercial-off-the-shelf (COTS) hardware tools, or creating their own custom designs. In both cases, it is best to use the same common software tools during the whole design-prototype-deploy process. NI LabVIEW offers a comprehensive approach to perform all these tasks within the same software development environment, providing a tight integration with different hardware options, including the possibility of generating C code to target specific hardware platforms used in custom embedded designs.
