Solid Split-Type Weighted Dummy

The Solid Split-Type Weighted Dummyis a premium, high-stability ballast system engineered for precise mass simulation in extreme testing environments. Unlike traditional water-filled units, this dummy features a solid core constructed from advanced silicone and high-density polymers, eliminating fluid sloshing and noise during high-dynamic maneuvers. Its innovative three-section modular design allows you to handle and transport heavy weights with ease while maintaining a fixed center of gravity (CoG). Originally developed from German automotive R&D principles, this dummy provides the durability and thermal resistance required for rigorous electric vehicle (EV) battery vibration tests, crash simulations, and theme park ride safety verification.

Applications

Solid Split-Type Weighted Dummies are widely used by automotive manufacturers both domestically and internationally.

Standards

Toyota, Honda, Nissan; Mercedes-Benz, BMW, Volkswagen; General Motors, Ford; Hyundai, Kia; as well as automakers from India, Pakistan, Europe, South Africa, the Middle East, and domestic Chinese manufacturers including SAIC, FAW, BAIC, Volkswagen, King Long, Yutong, JAC, Geely, BYD, Haima, and others.

Features

1. The dummy is divided into three sections: upper, middle, and lower. Each section has an average mass of 25kg. They can be stacked to form a single unit, secured with two 316 stainless steel anti-rust pins. Hand-tightened knobs screw into limit stops to lock the assembly, preventing disassembly.

2. Easy to transport: Remove the pins, disassemble the three sections, and move them individually with ease.

3. Designed for electric vehicle battery vibration and impact safety testing. Prevents liquid sloshing during vibration, eliminating changes in dummy center of gravity (C.G.) and noise generation.

4. Developed by a renowned German automotive manufacturer. Silicone material combines hardness with flexibility and resilience, withstanding intense vibrations, wear, and temperatures from -55°C to 250°C (actual testing range: -40°C to 90°C). Material remains stable, crack-free, and distortion-free throughout extreme temperature cycles.

5. Total mass tolerance controlled within ±0.04kg.

Parameters

75kg Class Weight Dummy / Water Dummy – 3-Piece Solid Type

Accessories

Compatible with sandbags in the following weights: 1. 2. 3. 4. 5. 6. 7. 8. 10. 15. 20. 25. 30. 35. 40. 50. 100kg

Test Procedures

1.Transport: Move the three 25kg segments individually to the vehicle or test rig to avoid heavy lifting strain.

2.Assembly: Stack the bottom (legs), middle (torso), and top (chest/head) sections. Align the connection holes.

3.Locking: Insert the 316 stainless steel pins through the segments and tighten the manual knobs until the limit is reached. Ensure the unit is rigid and does not wobble.

4.Placement: Position the 75kg dummy in the seat. For automotive tests, ensure the base is flush with the seat back to maintain the 240mm CoG height.

5.Execution: Run your vibration, collision, or thermal cycle test. The solid core ensures no internal movement during the procedure.

6.Disassembly: Loosen the knobs, pull the pins, and separate the segments for easy removal once the test is complete.

FAQ

1. Why should I choose a solid dummy over a water-filled one for EV battery tests?

In battery vibration testing, water sloshing creates unpredictable dynamic forces and shifts the center of gravity. A solid dummy provides a constant, "dead" mass, which is essential for obtaining clean, accurate data regarding the battery's mechanical durability.

2. Is the silicone material soft enough to avoid damaging high-end leather seats?

Yes. The bionic silicone is designed with a specific durometer that provides "softness with toughness." It mimics the pressure distribution of a human body, preventing the sharp pressure points often caused by metal or plastic weights.

3. How accurate is the 75kg weight rating?

We maintain an extremely tight tolerance. The total mass error is controlled within $\pm0.04$ kg, ensuring your test results comply with the most precision-sensitive international standards.

4. Can this dummy be used in a salt spray or high-humidity chamber?

Absolutely. By using 316 stainless steel for all pins and knobs and high-grade silicone for the body, the dummy is virtually immune to rust and corrosion, making it perfect for aging and environmental stress tests.

5. Do I need tools to assemble or disassemble the dummy?

No tools are required. The system uses manual hand-tighten knobs and quick-release pins, allowing a single technician to assemble or disassemble the unit in under two minutes.
