ABSTRACT

Purpose. Develop a methodology for modeling the elastic element of a screen using the SolidWorks Motion environment.

The methods. The methodology for modeling the elastic element of the screen was developed on the basis of the Dassault Systèmes SolidWorks software product. The mathematical expression that describes the behavior of the spring built into SolidWorks Motion is derived. Also, in the same software product, graphs are built that reflect the behavior of the system in which the spring model is used.

Findings. Based on the study of the computational experiment data, a mathematical model of the spring was developed for use in the SolidWorks Motion software product. An analytical expression for the critical vertical force corresponding to the transition of the spring from the upper position (compression spring) to the lower position (tensile spring) is obtained. The spatial vibrations of a plate supported by four springs along its perimeter are investigated. It was found that the plate exhibits behavior similar to a system with three degrees of freedom. In order to reduce the deviations, the use of horizontal springs was proposed. The methodology used was applied to the dynamic analysis of the screen.

The originality. The mathematical model of the spring, which is embedded in the SolidWorks Motion software product, is determined. An expression is given that determines the value of the critical load, which will lead to a change in the position of the spring.

Practical implementation. The equation that describes the state of a spring can be used when calculating elastic elements of machinery using SolidWorks Motion methods. This is especially relevant when designing mechanisms and systems where it is necessary to accurately predict the behavior of elastic elements during their operation. The use of simulation software allows engineers to optimize designs and test various load scenarios without creating prototypes.

Keywords: SolidWorks Motion, spring, mathematical model.
