Shock test bench XUD series

performancecomputer-controlledshock absorber

Overview
XUD is an ultra-high dynamic electric test bench dedicated to shock absorbers and suspensions. Designed for short-duration performance tests, the XUD series delivers accelerations up to 100 G and peak forces up to 31.2 kN.

Key specifications (summary)

• Max. peak force: up to 31.20 kN (XUD030)
• Max. dynamic force: up to 8.10 kN (XUD030)
• Max. acceleration: up to 100 G
• Max. test speed: 6.00 m/s

Type of test
Performance tests, high-dynamic characterization

Applications

• Shock absorbers
• Vehicle suspension components

Detailed features

• Closed-loop control of force and displacement via the Test Center control system
• Reproduction of sinusoidal, triangular and custom profiles
• High-resolution data acquisition (24 bit)
• Variable installation positions and remote controller placement
• Flexible graphical programming of test sequences
• Wide range of grips, testing tools and load cells
• Integration with extensometers and climatic chambers
• No mechanical transmission — low maintenance and high dynamic response
• High-efficiency electric motor for low power consumption
• Synchronized operation of up to 10 actuators (e.g., 4-poster systems)
• Configurable geometry — available as linear actuator without upper crossbeam
• Programmable speed up to 6,000 mm/s and stroke > 200 mm
• Simple installation: single electrical socket and compressed air required
