Overview

Durability test systems are required for insuring the reliability of steering systems throughout the product life cycle. Tests such as impact and strength testing require dynamic actuation and control. LINK has a wide range of capabilities for durability and dynamic test systems including:

• Single and Multi-Axis (2 to 6 DoF) Servo-Hydraulic Dynamic Durability Test Systems
• Dynamic Impact Test System
• Steering Input, Sector Shaft Loading, Tie Rod Loading, Jounce/Rebound, and Rack Mount Vibration Actuators
• Servo Control with Real-Time 4 kHz Control Loop Closure
• Block Cycle, Parking Cycle, and Dynamic Testing
• Road Load Simulation
• Time History Playback
• Specialized Control Modes and Mode Switching Functions
• Environmental chambers and mud/slurry systems

Key Features

• Highly dynamic rack end impact actuator
• Protective hydraulic cushions at the ends of the actuator travel
• High flow servo valves
• 3500 Control System for high fidelity control and data acquisition
• Velocity gain control
