Features
Simulates real-world vertical vibration loads with sinusoidal motion.
Evaluates fatigue life of seat frame, cushion foam, and fabric upholstery.
Upper jounce assembly includes body form and adjustable weights for realistic load simulation.
Height and lateral adjustment ensure proper alignment and horizontal parallelism.
Overhead crane for easy installation and removal of test samples.
Servo-hydraulic lower jounce table with PC-based closed-loop control.
Programmable vibration frequency, amplitude, and acceleration with four control modes: table displacement, table acceleration, upper assembly displacement, and upper assembly acceleration.
Optional slave stations allow simultaneous testing of multiple samples.
Designed to prevent excessive inertia loads, ensuring realistic and reliable test results.
