Anti-Vibration Studies

Large numbers of air conditioning/sanitary equipment and electrical equipment are installed when constructing buildings, factories, and other such facilities. In order to prevent vibration difficulties caused by these equipment in advance, we will predict the vibrations that will occur during equipment operation from the structural specifications and the equipment's exciting forces, and select the appropriate vibration isolator.

FEM Analysis

When the eigenvalue component of a structure is a cause of vibration disturbance, it may be necessary to understand the vibration mode shape when taking measure. By performing FEM analysis, it is possible to grasp the accurate vibration shape even for complex structures.

Stage Response Prediction of Precision Equipment

Some devices used in the precision part manufacturing process are accompanied by high-speed stage movement, yet generate a large oscillating force when starting and stopping, which affects the device itself. When taking anti-vibration measures in particular, there is concern that large fluctuations may occur due to the low rigidity of the supporting springs. In such cases, we must predict the response level and vibration convergence time.

Vibration Suppression Study

For sensitive vibration disturbances (floors, horizontal building vibrations, bridges, etc.) due to the response characteristics (eigenmodes) of structures, vibration control measures using dynamic vibration absorbers (TMD, AMD) can be effective. We will select an appropriate vibration control device based on the specifications and uses of the target structure and vibration data, and then predict the effect it will have.

The necessity of introducing the vibration damping device can be determined from the vibration prediction calculation
