Office Chair Comprehensive Testing Machine (Armrest and Seat Surface)

Product Overview

Analysis of the Product Uses of the Office Chair Comprehensive Testing Machine (Armrest and Seat Surface)

The office chair comprehensive testing machine is a core device in the field of furniture quality inspection. It is mainly used to evaluate the durability, strength and safety performance of key components of office chairs, such as armrests and seat surfaces. The following comprehensively analyzes its core uses from dimensions including testing scenarios, technical parameters, industry applications, etc., in combination with international standards and actual measurement cases.

I. Core Testing Functions and Scenarios

Armrest Strength and Durability Testing:

Simulating Daily Pressure Scenarios: Vertical or lateral forces are applied to the armrests through air cylinders or servo motors to simulate actions such as long-term leaning and side pressure of the human arm. This is used to detect the anti-deformation ability of the welding points and connectors of the armrests.

Testing Standards: According to standards such as EN 1728 and BIFMA X5.1, set the number of cycles (e.g., 100,000 times) and the load range (e.g., 0 - 200 kg), and record failure situations such as cracks and looseness of the armrests.

Seat Surface Fatigue and Static Load Testing:

Seat Surface Load-Bearing Simulation: A constant weight (e.g., 100 kg) is loaded on the seat surface. Through reciprocating impact or continuous pressure testing, the collapse of the seat cushion material, deformation of the frame, and the durability of the gas spring are evaluated.

Destructive Testing: Some devices support ultimate load testing. By gradually increasing the pressure until the seat surface structure breaks, the maximum load threshold is determined, providing data for design optimization.

Dynamic Composite Testing:

Simulate the armrest pressure and seat surface impact simultaneously to detect the overall stability of the office chair under complex force application scenarios. For example, when a heavy object is placed on the seat surface, a lateral force is applied to the armrests to verify the anti-fatigue performance of the connectors.

II. Technical Advantages and Industry Applications

Technical Parameters and Equipment Characteristics:

Precise Control: Adopt a PLC controller + touch screen operation interface, supporting the free adjustment of parameters such as force value (0 - 300 kg), stroke (0 - 300 mm), and speed (10 - 30 times per minute).

Multifunctional Adaptability: The modular design enables quick replacement of fixtures, adapting to office chairs of different sizes and structures, such as swivel chairs, conference chairs, and e-sports chairs.

Data Recording: High-precision sensors are built-in to record displacement and pressure curves in real-time, and generate test reports, supporting export in formats such as ISO and ASTM.
