Vehicle Dynamics Testing

С��APP is a leading provider of specialized vehicle dynamics testing services to the global automotive, defense, rail, aerospace, and transportation sectors. We provide our customers with a wide range of engineering and testing services covering everything from subsystem and component testing to full vehicle durability testing, road load data acquisition and data analysis related testing services.

Dynamics testing is a vital part of the vehicle development process, allowing the enhancement of vehicle performance, durability and reliability.

From studying the responses of a vehicle in various dynamic situations to assessing how a component or subsystem influences the overall vehicle ride, handling, and performance, our Engaged Experts implement dynamics testing programs specifically designed for your products.

С��APP’s vehicle dynamics testing capabilities

С��APP has extensive vehicle dynamics testing capabilities that cover all of the sectors in the transportation industry, including passenger cars and trucks, medium and heavy trucks, transport trailers, off-highway equipment (agricultural and construction), military vehicles, school buses, commuter coaches, transit buses, rail, and more.

Our team of dynamics experts can develop comprehensive test plans tailored to fit your specific needs, from specialized engineering services to Noise, Vibration, Harshness (NVH) and Buzz, Squeak and Rattle (BSR) testing to identify noise sources, minimize noise and vibration as well as squeak and rattle.

Our engineering services include duty cycle development, proving ground and customer in-service life correlation, road load data acquisition (RLDA) and instrumentation, computational data analysis, computer model validation, test plan and procedure development, custom transducer design, build and calibration.

The С��APP advantage

All of our vehicle dynamics testing services are performed in highly secure environments to ensure customer confidentiality at all times.

Vibration Testing & Analysis Services

A critical part of vehicle development, vibration testing and analysis help validate your design to see if it will withstand its intended environment.

Vibration testing simulates a variety of transportation scenarios, operating environments, and the effect of external vibration within a test environment. С��APP’s vibration testing facilities are comprised of electro-dynamic and servo-hydraulic systems that can replicate low and high-frequency conditions, offering state-of-the-art solutions to your most challenging requirements.

The vibration testing methods we perform include:

Sinusoidal Vibration Testing

Sine on Sine
Sine on Random
Resonance Search and Dwell Testing
Phase Track and Dwell
Acceleration, Velocity & Displacement Control

Random Vibration Testing

Narrow Band Random on Random
Sine on Random
Fatigue Damage Spectrum
Random Import

Drop & Shock Testing

Used to measure the impact of sudden acceleration caused by explosion, drop, or collision, shock testing is a valuable tool to prepare products for harsh industrial, transportation, and military environments.

Drop and shock testing involves subjecting components to acceleration up to 50,000 g at target time durations allowing further analytical analysis. We then evaluate the product for damage and stress, and ensure that it can meet the demands of its work environment.

Our drop and shock testing capabilities include:

Operational shock and crash safety
Gunfire simulation
Classical shock
Decaying sine wave testing
Bump testing
Impulse testing
Drop testing
Impact testing
Pendulum Impact
Transportation Shock and Vibration

Noise Testing

Noise testing allows determining fit and wear of vehicle components as they are perceived acoustically.

С��APP combines years of noise testing experience with state-of-the-art laboratory testing and simulation facilities to study the noise characteristics of vehicles and vehicle components, and to give you results closer to the real vehicle behavior in its application.

The vibration testing methods we perform include:

NVH/Squeak and rattle problem solving
Buzz, Squeak, and Rattle (BSR) specification testing
Experimental modal analysis, point mobility, acoustic sensitivity
Static bending and torsion
Sound quality/intensity analysis
Drive by noise evaluation
Transfer path analysis
Signature analysis / acoustic sensitivity
