Experimental and numerical analysis for study a stress of new type lifting platform construction for car relocation

Popis výsledku v původním jazyce

This article studies the mechanical loading of a new type of lift platforms and it is connected to study of other types of lifting platforms, which has been published previously. For a stress assessment which acts in individual parts of a platform lift for moving of cars dynamic analysis and experimental studies were performed. The analysis of loads shows that immediate loading of the platform by bending momentum causes that a construction of platform has to be suitably fixed. First experimental measurements were carried out on the real platform for obtaining of trajectory, velocity and acceleration during movement. Subsequently, the model analysis of the lifting platform using a four point Runge-Kutta method was assembled. Depending on the dynamic motion the stress distribution in the critical parts of platform was investigated. The model analyses was shown that a step loading during acceleration and deceleration of the platforms leads to a dynamic impacts that are unsafe from point of view of long term usage. The consequence of said consist in repeated overloading of pivots, bearings, rollers and other parts. Also the dynamic stress may be accompanied by the resonances. Therefore the design of lift platform has to be optimized to ensure adequate safety.
