Botou Office Chair Rotation Tester

The Botou office chair rotation tester generally refers to professional equipment used to evaluate the rotational performance and durability of the base of an office chair. Its core function is to simulate the rotational movements of the human body on the chair seat during daily use and to test the mechanical strength, wear resistance, and long-term stability of the base's rotating mechanism by setting parameters.

Equipment Functions and Test Types

1. Edge Pressure Test: By applying vertical or lateral pressure, it evaluates the load-bearing capacity, structural deformation, and material fatigue of the base's edges. For example, it tests the base's resistance to deformation when subjected to shifts in body weight, ensuring that it will not break or undergo permanent deformation due to localized stress during long-term use.
2. Rotation Accuracy Test: It records angular deviations, axial runout, and changes in resistance during rotation. For example, it detects whether the chair seat experiences stuttering, misalignment, or uneven resistance during rotation to assess the machining accuracy and assembly quality of transmission components (such as bearings and gears).
3. Rotation Count Test: By continuously rotating to a set number of cycles (e.g., 100,000 times), it evaluates the product's service life. For example, it simulates the rotation frequency of an office chair over a 5-year usage period to verify the wear resistance of the base materials (such as plastics and metals) and the durability of the lubrication system.
4. Rotation Stability Test: It monitors wear, noise changes, and structural deformation of the base during long-term rotation. For example, it detects whether increased noise is caused by bearing wear or whether the connection points of the support frame become loose due to vibration.

Equipment Composition and Working Principle

The equipment mainly consists of a mechanical loading system, a drive system, a sensing and detection system, and a control unit:

• Mechanical Loading System: It applies vertical or lateral pressure through cylinders or motors to simulate body weight and movement force.
• Drive System: It controls the rotation of the chair seat at a set speed (e.g., 5-15 revolutions per minute), with some models supporting alternating forward and reverse rotation tests.
• Sensing and Detection System: It integrates pressure sensors, angle encoders, and vibration sensors to collect real-time data on pressure, rotation angle, and noise.
• Control Unit: It sets test parameters (such as rotation speed, load, and cycle count) and automatically records data to generate test reports.

Application Value

Through standardized testing procedures, this equipment provides office chair manufacturers with quantitative data for optimizing product design (such as improving base structure and selecting more wear-resistant materials), enhancing product quality, and meeting international standards (such as BIFMA and EN 1335) for rotational durability.
