Abstract:
In case of general home appliance product, resin parts are widely used due to economic efficiency and structural design freedom. However, Resin parts have shape and dimensional variations depending on the injection and cooling conditions when they are injected. When various parts are assembled, the accumulated tolerances may cause degradation of product performance or NVH problem. Particularly, the tolerance of the system in which its operating conditions are varied during operation becomes greater. In this study, Monte Carlo simulation is used to obtain the tolerance variation of the humidifier parts considering the changing operating conditions. And multibody dynamics analysis is also used to secure the operability of the driving part and low noise level. Experiments were also carried out to verify the noise and vibration level. This study is expected to be useful in the early stage of research before prototyping.
