The impact of the modelling method of the front loader on the accuracy of the FEM calculations results
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2018, Vol 63, Issue 4
Abstract
The article discusses selected issues of front loader modelling for the needs of FEM calculations. Particular attention was paid to the necessity of correct modelling clevis pin connections and hydraulic cylinders. In the case of hydraulic actuators, the effects of a different approach in modelling the actuators on the quality of the structure under operating load were demonstrated. Differences in the modelling cylinders equipped with a hydraulic lock and cylinders connected in parallel without locks were taken into account. The results of calculations obtained on the examples are discussed and the methodology of self-control of the results of FEM computations is presented. Some examples of various machines and possible errors during strength analyzes were also presented.
