Identification of the nonlinearity in mass-spring system via experimental method

Algebraic Identification Method for Mass-Spring-Damper System

In this paper we describe a procedure for parameters identification using an algebraic identification method for a continuous time constant linear system. We make a specific application in the determination of the parameters mass-spring-damper system. The method is suitable for simultaneously identifying, both, the spring constant and the damping coefficient. It is found that the proposed metho...

Identification of Nonlinear Modal Interactions in a Beam-Mass-Spring-Damper System based on Mono-Frequency Vibration Response

In this paper, nonlinear modal interactions caused by one-to-three internal resonance in a beam-mass-spring-damper system are investigated based on nonlinear system identification. For this purpose, the equations governing the transverse vibrations of the beam and mass are analyzed via the multiple scale method and the vibration response of the system under primary resonance is extracted. Then,...

Modeling the feeding process in gill-box using non-linear mass-spring system

Notes on the Virtual Spring Mass System

A force feedback system, such as the haptic wheel used in the EECS 461 lab, is capable of exhibiting a wide range of interesting phenomena. It is useful to remember that the system consists of a mechanical device (the wheel in our case), with two feedback loops wrapped around it. As shown in Figure 1, one feedback loop consists of (i) a sensor such as an encoder, tachometer, or strain gauge, (i...

Mesh Topology Identification for Mass-Spring Models

In surgical simulations, the two most popular approaches to model soft tissues are Finite Element Method (FEM) and Mass-Spring System (MSS). Main advantages of FEM are accuracy and realism. Furthermore, the model allows the direct integration of experimentally obtained biomechanical tissue parameters. However, computation times remain high, limiting real-time application of the method. In contr...
