1、 Core functions andScope of Application
1. Objective of the test
Evaluate the structural stability, connector strength, and durability of table furniture under simulated drop impact, ensuring its ability to resist accidental drops in practical use, and guaranteeing safety and functionality.
2. Scope of Application
Fixed, foldable, or movable desk furniture suitable for home, office, and public use, including different materials and structural types.
3. Test equipment
Drop testing machine:
Adjustable range of drop height:300mm~1500mmSet according to product weight classification (such as ≤10kgset300mm,10~20kgset500mm,>20kgset800mm).
Material of falling surface: concrete or steel rigid plane, surface flatness ≤2mm/m², Ensure uniformity of impact.
Release mechanism: Electromagnetic control or pneumatic release, allowing the sample to fall freely without rotation, avoiding human interference.
Data acquisition system: accelerometer (range ≥)50gAccuracy ±5%)High speed camera (frame rate ≥)1000fps)Record the impact dynamics and structural response.
Auxiliary tool: Level (accuracy ±)0.5°), steel tape measure (accuracy ±)1mm)Torque wrench (accuracy ±)3%).
4. Sample preparation
Quantity: At least for each type of product3One sample to ensure representativeness.
State adjustment: Sample at temperature(23±2)℃, relative humidity(50±5)%Preprocessing in the environment24Eliminate the influence of environmental factors within hours.
Load simulation: Apply static loads according to standard requirements (such as desk loading)50kgTable loading30kg)Placing drawers or cabinet doors5kgSimulate the usage status of the counterweight.

Falling height |
According to product weight classification: |
Falling direction |
Corner, edge, and surface drop in three directions, repeating in each direction3The second (total)9Next time). |
Impact velocity |
By calculating the height, the formula is:v = \\sqrt {2gh}v =2gh(g=9.8m/s²g=9.8m/s2). |
Impact energy |
Calculation formula:E=mghE=mgh(mmFor the quality of the sample,hhFor the height of the fall. |
3、 TestingstepAnd explanation
Positioning the specimen: Place the loaded specimen at the center of the drop surface, ensuring that the levelness is ≤1°.
Select drop point:
Corner drop: Intersection point of the diagonal of the specimen.
Edge drop: the midpoint of the long edge.
Face Drop: Geometric Center of Desktop.
Release the sample: achieve free fall through electromagnetic or pneumatic mechanisms, and record the data of the moment of impact.
Inspection and recording:
Visually inspect for structural deformation, loose connections, coating detachment, etc.
Functional testing: Check if drawer slides, folding mechanisms, etc. are functioning properly.
Repeat experiment: Complete in order of direction9Repeated drops and cumulative damage.
Qualification assessment
Structural integrity: No fracture, permanent deformation, or detachment of connectors.
Function retention: drawers, doors, and other components can be opened and closed normally, and the folding mechanism is not stuck.
Safety: No sharp edges or fragments generated.
Data recording and reporting
Required fields: Drop height, direction, frequency, specimen status, damage mode.
Optional: Impact acceleration curve, high-speed video screenshot, torque change data.
Precautions
Before the experiment, the equipment needs to be calibrated to ensure that the drop height error is ≤±5mm.
When conducting multiple sample tests, intervals are required10Minutes to avoid equipment overheating.
Special structures (such as glass tabletops) require additional protective measures to prevent debris from splashing.
