DYM R&D
Design Analysis
We conduct research to optimize the structure and design of bearings through computer simulations and experiments. This allows us to design efficient bearings that minimize load distribution and friction.
During this research process, we consider various load conditions and operating environments to derive optimal design variables and explore structural features that can enhance bearing lifespan and performance.
Pressure Distribution
Pressure distribution refers to the distribution of pressure applied to the surface of a bearing.
Since bearings are used to support loads, the pressure generated at specific points is very important. For stable and accurate operation, it is ideal for the pressure to be evenly distributed.
Temperature Distribution
The temperature distribution represents how heat is spread within the bearing and its surrounding areas.
If the temperature becomes too high, components of the bearing may become damaged or deformed, which can ultimately lead to bearing failure.
Data Report
DYM supports engineering solutions by modeling and analyzing the physical characteristics of fluid dynamic bearings, such as fluid flow, pressure, temperature, and dynamic coefficients. This allows customers or engineers to understand results through visualized simulation analysis and make optimal decisions.
