Dynamic Modeling of a Front-Loading Type Washing Machine and Model Reliability Investigation
Abstract
:1. Introduction
2. Modeling an FL-Type Washing Machine
2.1. System Configuration
2.2. Derivation of Equations of Motion
- The cabinet is fixed to the ground.
- Axial rotational motion of the tub is ignored.
- Torsional deformation of the shaft relative to the tub is ignored.
- Translational motion of the drum relative to the tub in the axial direction is ignored.
- An unbalance mass is fixed to the drum.
- The rotational motion of the drum is prescribed as a function of time.
2.3. Linearization of the Equations of Motion
3. Numerical Results and Discussion
3.1. Validation of the Nonlinear Analytical Model
3.2. Modal Analysis with the Linear Model
3.3. Comparison of the Nonlinear and Linear Analytical Models
4. Conclusions
