Advanced Dynamic Material Characterisation Under Real-World Loading Conditions
The Pulsed Mechanical Analyzer (PMA) is an innovative testing system designed to characterise the dynamic mechanical behaviour of elastomers and polymer materials under realistic pulsed loading conditions. By measuring the complex Young's modulus (E*), modulus magnitude (|E|), complex compliance (D*), and loss factor (tan δ) at frequencies from 100 Hz to 1 kHz, the PMA provides highly accurate material data for product development, research, and quality control.
Unlike conventional testing methods, the PMA evaluates material behaviour under rapid, high-deformation loading conditions, delivering practical insights into damping performance, stiffness, and glass transition temperature as experienced in real-world applications.
Standards
- DIN 53512
- ASTM D7121
Applications
The Pulsed Mechanical Analyzer is ideal for evaluating the dynamic mechanical properties of elastomers and polymer materials subjected to short-duration, pulsed deformation. It is particularly suited for assessing:
- Dynamic stiffness and elasticity
- Energy loss and damping behaviour
- Glass transition temperature under dynamic loading
- Material performance during impact and vibration
- Components exposed to repeated mechanical stress
- Product development and material optimisation
- Production quality control
Typical industries include automotive, aerospace, defence, industrial manufacturing, medical devices, research laboratories, and materials engineering.
Product Overview
The Pulsed Mechanical Analyzer (PMA) enables precise measurement of dynamic material properties under realistic operating conditions. The system determines the complex Young's modulus (E*), modulus magnitude (|E|), complex compliance (D*), and loss factor (tan δ) within the millisecond range using frequencies between 100 Hz and 1 kHz. Temperature-dependent testing is also available as an option.
One of the PMA's key advantages is its ability to determine the glass transition temperature while the material is under pulsed mechanical loading. This provides a far more realistic assessment of low-temperature material behaviour than conventional static testing methods, making it especially valuable for dynamically loaded rubber and elastomer components.
Fast, automated and highly reproducible testing delivers practical material data for engineering design while making the PMA equally suitable for routine quality assurance in manufacturing environments.
Key Features
Innovative Pulsed Mechanical Analysis
The PMA introduces a unique measurement technology that expands the capabilities of traditional rebound resilience testing. By accurately determining the storage modulus and loss factor under dynamic loading, it delivers material characteristics that were previously difficult to quantify.
This advanced approach enables engineers to better understand material performance under actual service conditions, improving product design and reliability.
Fully Automated Testing
Testing is initiated with the press of a button.
The automated measurement sequence positions the specimen, performs the complete analysis, and calculates all required parameters without manual intervention. This reduces operator influence, minimises errors, and ensures exceptional repeatability.
Large material deformations of 20–80% are achieved within milliseconds, while complete temperature-dependent testing can be performed in as little as 20 minutes.
Temperature-Dependent Material Analysis
The integrated temperature sensor continuously records specimen temperature throughout the test sequence.
Measurements can be performed across a wide temperature range, including testing down to –50°C using pre-conditioned specimens stored in a standard laboratory freezer, eliminating the need for expensive environmental conditioning equipment.
The result is reliable, repeatable measurement of material properties across operating temperatures.
