Lifting platforms with scissor mechanism

Development of Computational software for the assessment of limit states stress, deformation and stability of the lifting platforms was a research project in cooperation with our industrial partner LIFTCOMP Inc. This project was funded by the grant program of the Moravian-Silesian region and by the project POSTDOCI II – New creative teams in priorities of scientific research CZ.1.07/2.3.00/30.0055.

Lifting platforms are machinery which must be designed on the basis of the computational procedures and good engineering practice. For safe and reliable operation of the lifting platforms conditions defined by the mechanical strength and deformation, the buckling stress and the stability of the platform due to its turn-over in all operational and load conditions are prescribed. The design of these platforms must be effective so that the end user has received a product with high added value.

The main objective of the project is research work leading to the development of the software applications using computational modelling. By means of programming system MATLAB GUI the software applications were created that allow a comprehensive assessment of the limit states lifting platforms with scissor mechanism. Utilization of the software by anyone else than its owner LIFTCOMP Inc. is dependent on acquiring a license. Screenshots of the produced software are shown in figures below.
