The Water-filled Dummy (Ballast Weight Dummy) is a highly practical simulation tool designed to replicate human occupant mass in vehicle testing environments. Constructed from high-strength, impact-resistant Polyethylene (PE), this dummy features a hollow-core design that allows you to adjust its total weight by filling it with water, sand, or high-density metallic grit. Its specialized form factor is optimized for secure fastening with standard automotive seatbelts, providing you with a stable and repeatable ballast solution for vehicle dynamics, suspension tuning, and safety system verification.
Applications
Water-filled 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.Seatbelt Compatibility: The anatomical curvature and structural rigidity allow you to bind the dummy securely using standard 3-point or 5-point vehicle seatbelts without slippage.
2.Adjustable Mass Management: You have the flexibility to use water for standard occupant weights or high-density solids like iron sand to simulate "overweight" scenarios or cargo loads.
3.Optimized Center of Gravity: The 240mm base height and internal volume distribution ensure the center of gravity (CoG) remains consistent with a seated human, providing realistic vehicle dynamics.
4.Industrial-Grade Durability: The high-strength PE shell is designed to resist cracking, UV exposure, and impact, ensuring long-term use in both laboratory and outdoor track environments.
5.Large Diameter Inlet: The 86mm opening allows you to fill or drain the dummy quickly, significantly reducing setup time between test cycles.
6.Highly Customizable: The system supports the integration of internal sensors or external lifting straps and rings to suit your specific laboratory workflow.
