Automotive Powertrain Performance Evaluation

We offer a wide range of tests from unit evaluation to complete vehicle evaluation. With reliable measurements using our in-house equipment, we support automobile development.

  • Automobile Powertrain Performance Evaluation_No.1
Automobile Powertrain Performance Evaluation_No.2

Equipped with facilities capable of evaluating engine and drive system units, powertrain units, and various vehicle conditions, we are engaged not only in contracted testing as requested but also in joint research and development with our customers.
At the Utsunomiya Technical & Product Center, we operate a total of 8 facilities, including Engine Bench X 4, Transmission Bench X 2, Real Vehicle Transient Bench X 1, and Chassis Dynamometer X 1, focusing on automotive testing centered around the powertrain.

Noise and Vibration Control

We offer contract measurements and consulting for improvements and challenges related to acoustics and vibrations.
From problem setting, understanding phenomena, to effect confirmation, we can support you from any point in the resolution process according to your situation.

(SoundPLAN is a case of contracted measurement in the Japanese commercial flow.)

  • Noise and Vibration Control
Grasping a phenomenon

Clarification of challenges in solving sound and vibration issues.

Localization of the site and elucidation of the mechanism.

"Characteristics in the time domain and frequency domain," "the complex component structure where challenges are interrelated" break these down,
and determine the targets for solutions.

Proposal for reduction method

Once the target for design change is determined, the next step is to implement specific design changes regarding how to address acoustic and vibration design.

effect confirmation

Confirm the effects before and after the measures.

Sound is particularly a sensory quantity, so merely reducing it is not the goal.
In acoustic and vibration consulting, it is possible to provide consultation and support even at this stage of the process.
