TÜV SÜD’s onsite mCREST 4-poster testing solution

With TÜV SÜD’s mobile Combined Road Environmental Simulation Testing (mCREST) unit, your engineering team can immediately access advanced, onsite BSR (Buzz, Squeak and Rattle) testing. This mobile, climate-controlled chamber and 4-poster system replicate real-world road conditions through high-performance Servo Electric Actuators (SEA), identifying and eliminating squeak, buzz, and rattle issues at every stage of your product lifecycle.

We are the only global organization that can bring our equipment and expertise to your manufacturing site. TÜV SÜD’s 30 years of testing expertise and mCREST’s adaptable design make early detection and resolution of manufacturing-related issues straightforward, helping you optimize launch efficiency and product reliability. 

Elevate your bottom line

The mCrest offers immediate, cost-saving benefits by addressing quality issues onsite. Detecting and resolving quality issues in real-time supports on-time delivery, lowers manufacturing costs, and reduces post-launch warranty claims. TÜV SÜD’s mCrest supports Immediate Containment Actions (ICAs) and Preventive Corrective Actions (PCAs), leading to a faster ROI and improved product reliability. With TÜV SÜD’s extensive mobile testing experience, the mCREST delivers the precision and insights needed for effective engineering validation and product launch success.

Environmentally controlled, customizable testing – anywhere you need it

The mCREST’s mobile capabilities go beyond traditional testing environments. Housed in two 45-foot ISO containers, it provides complete environmental control from -40°C to 60°C, suited for diverse testing scenarios. The unit enables tire-coupled and direct body excitation testing, delivering accurate NVH analysis under road-simulated conditions. Ready for use within 48 hours, mCREST requires minimal setup (35 ft x 80 ft footprint), maximizing your resources and minimizing logistics costs.

• Testing Range: SEA 4-poster actuators cover frequencies from 0–150 Hz, enabling complex road profiles 
• Temperature Control: Chamber range from -40°C to 60°C, utilizing 24 x 1000W heat lamps
• BSR (Buzz, Squeak Rattle) rated: Up to 21 kN peak dynamic force 
• Stroke: 170 mm peak-to-peak (6.75 in peak-to-peak) 
• Peak Force: 21 kN dynamic force (8.1 kN RMS) 
• Vehicle Capacity: Supports wheelbases from 94in to 179in; up to 12,600 lbs 
• EV Charging: NEMA 14-50 outlet for Level 2 charging (50A) 
• Power Requirements: 480 V, 400A, 3 Phase 
• Landing Pad Requirements: <1 in slope over a 10-ft span

The TÜV SÜD mCREST offers engineering teams a mobile reaction mass, making it deployable globally. Its capabilities include reproducing BSR road surfaces in a controlled setting and generating artificial road profiles with precise frequency controls. The unit’s design enables real-time results essential for daily manufacturing and launch needs. It’s fully operational in under 48 hours, adding agility to your quality processes. 

Why mCREST is essential for your launch strategy 

• Real-Time Issue Resolution: Resolve all quality issues immediately to maintain launch schedules and reduce rework. 
• Enhanced Quality and Compliance: Meet stringent industry standards pre-market, lowering the risk of costly recalls, warranty claims, and customer dissatisfaction.  
• Operational Efficiency: Avoid extensive logistics by bringing testing directly to your site, maximizing team productivity.
