In recent years, social demands for product performance have been increasing, as seen in efforts to further reduce vibration and noise in various devices and machines, the hybridization of automobiles, energy saving, and environmental measures. Under these circumstances, manufacturing sites are being required to conduct even more accurate experiments in product development. The Technology Development Center responds to these needs and enables high-precision, high-quality experiments.
The Technology Development Center is a hub that aims to develop technologies that truly contribute to manufacturing by having experimental analysis experts and CAE analysis experts share information and refine their skills together at the same site, in order to further enhance the value of experiment-driven CAE.
Features of the Technology Development Center
The 1st floor of the Technology Development Center is a vibration and noise testing area, and the 2nd floor is equipped with analysis servers and office functions for experimental data analysis and CAE simulation analysis. By having experimental analysis experts and CAE analysis experts work together at the same site while sharing information and know-how to tackle technical challenges, we advance sophisticated proprietary CAE technology development and contribute to our customer's design and development work.
In addition, to promote experiment-driven CAE, we develop engineers who have both experimental analysis and CAE analysis capabilities.
Large Surface Plate and Flexible Testing Space
On the 1st floor of the Technology Development Center, we established a new vibration and noise testing area divided into five sections. In every section, we installed a large embedded surface plate with an isolated, separated foundation that enables high-precision vibration measurement, and also adopted a simple anechoic-room structure using sound-absorbing materials.
Among these, the three central sections are connected without partition walls, creating a flexible testing space.
In addition, one of the two end sections is a hydraulic excitation room described below, while the other is designed as a high-load floor structure. In anticipation of increasing vibration and noise tests for EV powertrains, it is equipped with a large surface plate that can accommodate a dedicated motor bench in the future.
- Large Surface Plate
- Large T-slot embedded floor surface plate (4.5m ÁE3m)
By separating it from the general floor with an isolated foundation consisting of a concrete block more than 1m thick, we created a high-precision vibration testing environment that blocks background vibration. - Laboratories
- Width 6m ÁEDepth 12m ÁEHeight 5m
Two rooms are completely independent spaces
Supports testing of highly confidential specimens and long-stay customer testing work
Three rooms form one continuous large space, enabling highly flexible test layouts (Width 18m ÁEDepth 12m ÁEHeight 5m)
In addition to these facilities at the Technology Development Center, by combining them with the testing instruments we have long owned as listed below, we provide our proprietary experimental technologies to our customers.

Hydraulic Excitation System
Hydraulic excitation equipment has been introduced to enable tests such as small deformation testing of vehicle bodies in the ride comfort and handling stability domain through high-input excitation experiments that are difficult to achieve with electrodynamic shakers.
Features of the Hydraulic Excitation System
-
A compact, highly versatile excitation head enables experiments with a freely configurable layout
-
Supports random excitation, swept-sine excitation, combined excitation, and operational PSD excitation
Main Applications
-
Dynamic stiffness measurement of rubber components such as bushings; vehicle body hysteresis measurement
-
Tests for road-noise analysis by exciting the tire contact patch of a vehicle
-
Component fatigue testing
-
Seismic testing of electronic equipment
