Droplet resonance - internal flow

- In the resonant frequency, they have an infinite energy theoretically in spite of very low input energy

- Droplet dynamic behavior generates mode shape and internal flow

- Resonance effect can repin the contact triple line.

Thin film condition analysis

- we have many kind of thin circular films (AL, PP, PTFE, Cu, PDMS..)

- Computation of fundamental frequency and analyzing characteristics of films

Tilted & Micro patterned surface

- Surface patterned surface has different roughness

- Roughness factor is related with surface wettability

- Analysis of hydrophobic & tilted surface

The effect of vibration and viscous solution on surface treatment is shown.

- The functional surface is widely using in the industries fields. Surface treatment using vibration is one of the produce method.

- The experiment shows the effect of various vibration factors (frequency, voltage, etc..) and solution factors (viscosity, thickness, etc..).

- Compare simulation and experimental results with theory.

Vibration analysis using ANSYS in various fields.

- Vibration analysis for development of semiconductor wafer backgrinding system

- Vibration analysis of Electro-Optical Targeting System(EOTS)

- Vibration analysis of Close-In Weapon System(CIWS)

- Gun Firing Shock and Vibration Analysis

Study of Multi-axis horizontal Dynamic Antiresonance Vibration Isolator(DAVI) mount 

- DAVI induces anti-resonance in the system using control masses and level mechanisms.

By arranging DAVI biaxial direction, it is possible to respond to multi-axis vibrations in the horizontal plane.
