Contract testing and consulting services

Automotive powertrain performance evaluation

We offer a wide range of testing services, from unit evaluation to complete vehicle evaluation. Our reliable measurements, utilizing our own facilities, support your automotive development.

  • Automotive Powertrain Performance Evaluation - No. 1
Automotive Powertrain Performance Evaluation_No.2

We have facilities that allow us to evaluate individual engines and drivetrains, powertrain units, and vehicles in various conditions. In addition to contract testing, we also engage in joint research and development with our customers.
At the Utsunomiya Technical & Product Center, we conduct automotive testing, primarily focusing on powertrains, using a total of eight facilities: four engine benches, two transmission benches, one full-vehicle Transient Bench, and one chassis dynamometer.

Noise and vibration countermeasures

We offer contract measurement and consulting services to address improvements and challenges related to acoustics and vibration.
From defining the problem and understanding the phenomenon to verifying the effectiveness, we can support you at any stage of the solution process, depending on your situation.

  • Noise and vibration countermeasures
Understanding phenomena

Clarifying the challenges in solving acoustic and vibration problems

Identifying the affected area and elucidating the mechanism

By breaking down the "characteristics of the time domain and frequency domain" and the "complex component configuration in which the issues are interrelated,"
Determine the target for the solution.

Proposal of reduction method

Once the areas requiring design changes are determined, the specific design changes are implemented, including how to implement acoustic and vibration design.

Effectiveness check

Check the effects before and after the countermeasures.

Sound is a particularly subjective quantity, so simply reducing it isn't the only goal.
Acoustic and vibration consulting services can provide advice and support at this stage of the process.
