Explore Test Rigs

Built to Recreate Real Conditions in a Controlled Lab Environment

Test rigs help engineering teams bring critical vehicle and component validation into a precise and repeatable environment. Instead of waiting for full road programs, teams can reproduce road loads, damper motion, structural responses, and acoustic events with better control over force, displacement, speed, and repeatability.

For ATS customers, this means shorter development loops, cleaner data, and more confidence across durability, NVH, ride, handling, acoustic analysis, and regulatory validation work.

Automotive laboratory test rig

Where These Systems Add Value

NVH

Ride and Noise Validation

Support road input replication, body excitation, and pass-by noise workflows for acoustic and comfort-focused development programs.

R&D

Faster R&D Cycles

Move testing from the road into the lab for earlier validation, tighter iteration loops, and more repeatable comparison between setups.

DAQ

Better Measurement Control

Combine rig motion, sensor channels, speed, RPM, sound, and NVH analysis into a more structured engineering test environment.

LAB

Cleaner Operation

Modern electric actuation improves efficiency, reduces maintenance overhead, and supports more sustainable test operations.

SEA four poster road simulator

SEA Four + Four Poster

Based on eMpulse servoelectric road simulator systems, SEA Four and four-poster solutions are designed to reproduce real-world road inputs with high precision. These systems support four-poster, body-coupled, and aero-loading style applications for durability, NVH, buzz, squeak and rattle, research, and accelerated life testing.

The platform is positioned as a clean alternative to hydraulic solutions, with direct-drive electric actuation, lower maintenance demand, and strong test repeatability for suspension, chassis, and full-vehicle validation programs.

Why It Fits Advanced Vehicle Validation

Broad Force Range

Reference specifications describe modular force configurations up to 108 kN, helping match the system to NVH, research, and durability requirements.

High Dynamic Response

eMpulse positions the road simulator line for high-frequency profiles, field data reproduction, sine sweep, and PSD-based road input replication.

Energy Efficient Operation

The servoelectric architecture is described as significantly more efficient than hydraulic systems, helping reduce heat, fluid handling, and maintenance overhead.

Damper Testers

For damper characterization and durability work, the eMpulse load-frame platform is aimed at precise force and displacement control for suspension component testing. The referenced damper-testing brochure describes SEA Damper Test Systems as solutions for evaluating the performance, durability, and service life of shock absorbers, dampers, struts, and related components.

These systems are presented as clean, dynamically responsive electric alternatives to conventional servo-hydraulic equipment, making them well suited for repeatable suspension development, benchmarking, and endurance testing.

Damper testing load frame

Built for Performance and Extended-Duration Validation

Performance Characterization

Measure damping behaviour across different loads, speeds, and motion profiles to refine ride comfort, control, and stability targets.

Durability Programs

The brochure highlights higher continuous load capability for longer duration testing, which is especially useful in service-life and accelerated durability work.

Model Options

The referenced damper system brochure lists standard models at 10 kN, 21 kN, and 41 kN peak dynamic force capacities for different suspension development needs.

Pass-by noise testing system

Pass-by Noise Testing System

Drawing on Race Technology's pass-by noise system, this solution is intended for complete pass-by or drive-by noise measurement for both cars and motorcycles. The system combines a compact vehicle-mounted kit with a trackside PC and sound meters, connected through a wireless data link for real-time monitoring and result capture.

Race Technology also describes quick installation, direct RPM data from a car OBD connection, CAN and sensor inputs for motorcycles, and optical trigger-based test initiation with speed, RPM, distance, and sound results displayed and recorded in Performance Monitor software.

What the System Helps You Capture

PC

Trackside Recording

All data and results are logged at the base station for review, reporting, and repeatable comparison between test runs.

RPM

Vehicle Data Inputs

Supports RPM capture from car OBD interfaces plus direct CAN and sensor inputs for motorcycle applications.

OPT

Optical Triggering

An optical trigger starts the measurement sequence and supports automatic distance, speed, RPM, and sound event handling.

WF

Wireless Feedback

Wireless communication links the vehicle-mounted kit to the trackside PC and feeds results back for instant operator visibility.

imc WAVE

Based on the imc reference page, imc WAVE is a modular workstation for acoustic and vibration engineering used in NVH testing. It is positioned as a powerful software platform for noise and vibration analysis that supports acoustic measurements in road tests, structural analyses on the test bench, and vibration studies on machines.

The page describes analyzers for noise, vibration, rotation, and structure. It also notes step-by-step workflows from device configuration to calibration, measurement, professional evaluation, and print-ready reporting. ATS can therefore position imc WAVE as the software layer that complements physical test rigs by turning raw sound and vibration measurements into actionable engineering results.

imc WAVE NVH analysis software

Why It Fits a Test Rig Workflow

Noise Analysis

The reference describes standard-compliant sound pressure and sound power analysis for vehicles, electrical machines, and mechanical machines.

Vibration and Order Tools

It includes vibration evaluation, FFT signal analysis, and order analysis for rotating machinery.

Structure Workflows

imc WAVE structure is presented as a tool for impact hammer excitation analysis, transfer functions, stiffness, compliance, and acceleration spectrum evaluation.

FAQs

1. What is a four-poster test rig used for?

A four-poster rig is used to reproduce controlled road inputs at each wheel so engineers can evaluate ride, durability, chassis response, and NVH behaviour in a lab environment.

2. Why do teams use damper testers?

Damper testers help characterize shock absorber behaviour, compare setups, and run durability programs under repeatable motion, load, and speed conditions.

3. Can electric test rigs replace hydraulic systems?

For many applications, electric systems are chosen because they can offer cleaner operation, lower maintenance, strong control fidelity, and better energy efficiency.

4. What does a pass-by noise system measure?

It combines sound level measurement with speed, RPM, and trigger-based event handling to support drive-by noise assessment for cars or motorcycles.

5. What is imc WAVE used for?

imc WAVE is used for NVH analysis covering noise, vibration, rotation, and structural dynamic measurements with guided workflows and report-ready evaluation.
