GMW 15536 ​​Suspension Joint J Roll Endurance Test

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of GMW 15536 ​​testing. The GMW 15536 ​​Suspension Joint J Roll Endurance Test is a test procedure used by General Motors (GM) to evaluate the durability of suspension joints.

Suspension knuckles, also known as steering knuckles, are components of a vehicle's suspension system that connect the wheel hub, brake assembly and steering components to the vehicle's chassis.

The J Turn Endurance Test simulates the stresses and loads that suspension knuckles are subjected to during aggressive turning maneuvers. The test involves repeatedly subjecting the suspension knuckle to a J-turn maneuver, a fast, sharp turn made by reversing the vehicle's direction of travel.

During testing, the wheel hub is constrained to move in a circular path, while the suspension joint is attached to a test fixture that allows it to rotate around the steering axis. The test rig is designed to apply a force to the suspension link simulating the lateral loads and torsional forces experienced during a J-turn maneuver.

The test is performed for a certain number of cycles or until the suspension joint fails, whichever occurs first. Failure criteria may include visible cracks or deformation, excessive wear or loosening of components, or changes in joint dimensions or alignment.

The GMW 15536 ​​Suspension Knuckle J Roll Endurance Test is an essential tool for evaluating the performance and durability of suspension knuckles, which are critical components of a vehicle's suspension system. By putting suspension joints through rigorous tests, GM can ensure its vehicles are safe and reliable, even in harsh driving conditions.
