ISO 7176-11 Wheelchairs Test Dummies | Anthropomorphic Test Dummies for Wheelchair Stability and Durability Testing

The ISO 7176-11 Wheelchairs Test Dummies | Anthropomorphic Test Dummies for Wheelchair Stability and Durability Testing are professional test devices manufactured by KingPo. They are designed to simulate the mass and mass distribution of human occupants for stability, performance and durability testing of manual and powered wheelchairs, in full accordance with ISO 7176-11.

Each test dummy is constructed with three rigid segments (torso, thigh and lower leg) connected by high-precision pivots at the hip and knee joints. The hip pivot is located at (78 ± 25) mm in both X and Y directions, and the knee pivot follows the same tolerance, ensuring accurate kinematic simulation of human posture. All segmental masses and centres of mass are manufactured to the exact values and formulae given in ISO 7176-11 Tables B.1 and C.1–C.3, with linear dimensions rounded to the nearest millimetre and masses to 0.1 kg.

The torso, thigh and lower leg segments are equipped with rigid loading plates covered by high-density foam cushions that accurately transfer load to the wheelchair seat and backrest while preventing unrepresentative damage. The overall centre of mass is fully adjustable on-site to match the required Xdummy and Ydummy coordinates, allowing laboratories to configure the dummy for any mass within the 25–300 kg range with laboratory-grade repeatability. The entire assembly is robust, stable and engineered for thousands of test cycles in both static and dynamic conditions.

Testing Principle

The test dummies replicate the mass and mass distribution of a seated or standing human occupant. When placed in the wheelchair under test, they enable precise evaluation of static and dynamic stability, brake performance, obstacle-climbing ability, durability and other parameters as defined in the ISO 7176 series.

Common Error Mitigation

To achieve maximum repeatability, always confirm the overall centre of mass position and segmental mass distribution using the balance or scale method (Annex A) before testing. Ensure correct dummy positioning on the seat and backrest reference planes and verify pivot freedom of movement. Periodic inspection and replacement of foam cushions prevent compression set that could alter load distribution.

Primary Use Cases & Business Value

The ISO 7176-11 Wheelchairs Test Dummies are the internationally standardized anthropomorphic devices used to simulate human occupants with precise mass and centre-of-mass distribution. They enable wheelchair manufacturers and independent certification laboratories to conduct repeatable, traceable evaluations of static and dynamic stability, brake effectiveness, obstacle-climbing performance, structural durability and overall safety under realistic loading conditions, ensuring products fully comply with international safety and performance requirements.
