Preliminary modelling studies of an experimental test stand of a crane, for investigation of its dynamic phenomena of lifting and driving mechanism

In the article, the problem of designing and preliminary tests on experimental test bench was taken into account. Proposed test stand allows us to carry out a series of studies concerning the dynamic phenomena accompanying the lifting of the load. Presented test bench allows, among other things, measurements of data such as the acceleration of selected points of the girder and also of cargo, displacement of cargo and centre of the girder, along with measurement of stress in selected locations and the coefficient of dynamic surplus. The electronic part of the test bench was made using the PHIDGET and the Arduino platform. Owing to the full miniaturization and implementation of control and measurement systems from the application level, test stand allows testing new mechanisms for implementing control algorithms and studying the influence of control parameters on the values of dynamic coefficients characterizing the selected dynamic mechanisms. Such an approach provides the possibility, among other things, of full control of the systems using a computer, and thus an immediate analysis of the data, which is extremely important in process of verification in the phenomenological model creation of the analyzed crane mechanisms. The proposed approach enables the development of existing ones and testing new design solutions in scale (experimental) and pure software solutions (analytical).
