Title Software design of the dynamic testing system for parameters of a hammer impact
Abstract
The dynamic testing system for paremeters of hammer impact is researched in the thesis. The selection of sensors and data acquisition cards as well as the constituting method of the systemic hardware is introduced firstly. On this foundation, the platform of LabVIEW is used to design a set of real-time testing system, including the testing of the hammer hit real-time speet,acceleration,power,oil cylinder pressured and absorb energy.Also an appropriative data processing and analyzing software is developed aimed at the characteristics of the testing system. The thesis introduces the software design of each module in detail. Finally, the test results are given, and analysis are carried on the test data. The testing system designed can carry out acquisition of data, analysis of data, display of results and creation of report forms automatically. The interface of the testing system is very humanistic and well considered of the conventionalism and convenience for the customers.
