SP-02-07XX Four Poster Rig

Four Poster Test Rig is designed to test durability of most cars. A fully self-contained test rig combined with multi channel control system and user friendly application software simulates real time effects and performs durability, performance or vibration testing in a controlled laboratory environment.

Applications: 

• Assembly line squeak & rattle testing
• R&D testing for handling and ride comfort 
• Remote parameter control
• Road simulation based on deterministic road obstacles, PSD of road profiles of different grades
• Sub-structuring

Standard features:

• Fully self-contained rig
• Track and wheel base adjustments
• Multi channel data acquisition for measuring road-load data of various parameters like displacement,strain, velocity,acceleration,load etc. at desired locations on the test object
• Multi channel controller for control of four actuators at 4+ kHz loop update
• Advanced data analysis software to capture significant part of the measured time histories of the road-load data and infer the quality, performance and durability of the test specimen from the measured responses in the laboratory
• No cooling required applications
