Project Overview
In this Abaqus tutorial, the period of a mass-spring system is calculated using both the analytical solution and the Abaqus software.
The main objective of this tutorial is to first calculate the period of the mass-spring system using the analytical solution, then obtain the period using Abaqus, and finally compare the results obtained from both approaches.
Mass-Spring System
In this problem, the stiffness of the spring (k) is 400 N/m, and the concentrated mass is 2 kg.
These parameters are used to determine the period of the mass-spring system using the analytical solution and Abaqus.
Calculation of the Period
The period is the time required for the system to complete one full oscillation, or in other words, the time required for the system to return to its initial state.
First, the period of the mass-spring system is calculated using the analytical solution. Following that, the same system is modeled in Abaqus and its period is obtained from the numerical simulation.
Comparison of Analytical and Abaqus Results
The period of the mass-spring system obtained from the analytical solution is 0.444 seconds.
The period obtained from the Abaqus software is 0.44 seconds.
As observed from the results, the period obtained from Abaqus is in very good agreement with the result obtained from the analytical solution.
