Material friction stick slip testing machine
The Stick-Slip Tribological Test Stand is a laboratory testing system used to evaluate friction-induced stick-slip behavior and squeak noise risk between material pairs under controlled load and motion conditions.You can use this equipment to measure static friction force, dynamic friction force, coefficient of friction, maximum friction acceleration, and vibration frequency, providing quantitative data for tribological and NVH evaluation.
