Design and realization of the software about beam distributed dynamic load identification system based on LabVIEW

Distributed dynamic load identification is one of the difficult points in structural dynamic analysis, and has a great significance in the domain of engineering application. In this paper, we design a general distributed dynamic load identification system from the engineering practice requirement. The system adopts the thought of modular design, based on LabVIEW virtual instrument platform. And the system with the Bernoulli Euler beam as the main research object is designed to be used in engineering practice, based on distributed dynamic load identification theory of model coordinate transformation. The system can effectively utilize the powerful functions of virtual instrument platform, such as data processing and dynamic link library, and it has a good human computer interaction interface, generality and extensibility. In the last of this paper, the feasibility and practicability of the distributed dynamic load identification system is proved through an application example.
