Key Features
Breathable Fabric & Advanced Simulation:
The manikin’s skin is made from breathable fabric that mimics the thermal conductivity and radiation properties of human skin.
Modular Structure:
The manikin is designed with a modular structure, allowing for easy disassembly and reassembly, making it suitable for testing in constrained spaces.
High-Precision Temperature Control:
11 independent heating sections ensure uniform heat distribution and simulate temperature differences between body parts (up to 3°C).
Walking Motion Simulation:
The arms and legs are motorized, simulating walking movement to study the effect of motion on clothing thermal insulation and moisture resistance.
Automatic Water Supply & Control System:
Equipped with an automatic water supply system, it maintains real-time perspiration, adjusts skin temperature, and regulates sweat rate.
PID + Fuzzy Algorithm Control:
The system uses a combination of PID and fuzzy algorithms, ensuring precise control of temperature, humidity, and fluid distribution.
Thermal Comfort Evaluation:
The built-in thermal comfort evaluation model (EQT model) quantifies comfort in non-uniform thermal environments and provides reliable feedback on clothing comfort.
Safety Protection:
Includes anti-leakage protection, overrun alarms, and automatic power-off functions to ensure safe and reliable operation.
Customization
The Walter Sweating Fabric Manikin is suitable for a wide range of applications, especially in the testing of clothing and outdoor gear for thermal comfort, insulation, and moisture resistance. The standard 26-zone model meets most testing needs, but the system can be customized to include:
Faster transient response
Wider environmental testing ranges
Additional research capabilities
This flexibility allows the Walter Sweating Fabric Manikin to be tailored to various research and testing scenarios.
