Seminars/Webinars

This presentation will explain the process of vibration countermeasures targeted at vibration generated in factories, and the items to be considered for each process. In addition, several examples of actual countermeasures will be introduced.

This webinar will cover the Occupant Performance Evaluation Criteria for Floor Vibration (Vertical Vibration) and will include the following key points What is the Occupant Performance Evaluation Standard? How is it evaluated and what has changed with the revision?

The features of horizontal TMDs, which are ideal for wind sway control, will be introduced along with actual examples.

The causes and effects of wind shaking, as well as countermeasures and their examples, are explained in an easy-to-understand manner.

We will introduce the structure and features of each lineup of Yacmo's Vibration Damping Devices (TMD) for Vertical and Vertical applications, as well as case studies of these devices.

The lecture will explain the basics of knowing walking vibration, design concepts to avoid complaints, and how to deal with complaints in case they do occur, using actual examples.

We will introduce our new compact-sized horizontal AMDs that can be used as post-construction measures for new products to address wind, traffic, and other vibration problems related to habitability that have occurred after the completion of construction of mid- and high-rise buildings.

The need for upper and lower seismic isolation floors to protect critical equipment such as servers and supercomputers for infrastructure from the vertical vibration of an earthquake directly below will be briefly explained, and actual examples of long-term maintenance will be presented.

There are various types of vibration control measures, such as earthquake resistance, seismic isolation, vibration control, vibration damping, and vibration isolation. The differences between them are explained from the beginning.

We will explain countermeasure points on the theme of machine vibration countermeasures for production equipment and other machinery, along with examples of improvements.

Floor vibration countermeasures caused by road traffic vibration will be explained in an easy-to-understand manner using actual data.

Once the data has been quantified, it is time to evaluate it. There are various methods for vibration evaluation, depending on the purpose and type of vibration. The following is a brief explanation of the various methods for vibration evaluation.

This section discusses solid propagation noise originating from equipment and devices, and explains the concept of solid propagation noise and its countermeasure policy in an easy-to-understand manner with case examples.

Among the vibration control devices widely known as wind and microvibration countermeasures for habitability of building structures, this section explains how to determine simple specifications for passive-type TMDs and active-type AMDs.

What is vibration? What is frequency? and then explains the magnitude of vibration in dB and vibration level, and how to read vibration data in terms of time-series waveform and frequency response expressed in graphs in an easy-to-understand manner.

Using earthquake damage to industrial machinery and equipment as an example, the importance of BCP and various earthquake countermeasures and seismic isolation technologies are explained.

The causes of floor sway and the basics of effective vibration control as a countermeasure are explained, and several examples of improvements made by AMD are presented.

The book explains the basics of road traffic vibration, as well as practical details such as measurement and simple response prediction methods for environmental vibration design.
