Dynamic Stiffness Testing: Quantifying Component Performance for NVH and Durability
For engineers designing components for vibration isolation and performance under dynamic load, static stiffness is not enough. Dynamic stiffness testing is the critical analysis used to determine the viscoelastic stiffness properties of a product, component, or elastomer specimen when subjected to continuous movement.At Smithers, our testing is specifically designed to stretch, compress, or cycle the material under various loads, precisely measuring load and displacement across a range of frequencies. This data is essential for accurate NVH (Noise, Vibration, and Harshness) engineering and modeling. We provide the precise, dynamic data needed to validate performance to specific standards and ensure product reliability throughout its service life.
Advanced Dynamic Stiffness Testing Capabilities
We provide high-precision, flexible testing programs capable of handling both small specimens and large, complex assemblies, utilizing a wide variety of actuators and load cells to match your exact application requirements.| Capability Metric | Maximum Range | Engineering Value |
| Linear Load | Up to 10,000 lbs | Testing heavy-duty components like bridge joints and engine mounts. |
| Displacement (pk-pk) | Up to 6 inches | Simulating large, real-world deflections and travel. |
| Frequency Range | 0 – 200 Hz | Covering critical operational frequencies for engine vibration and vehicle dynamics. |
Common Applications & Components Tested
Our dynamic stiffness testing is vital for any component that functions as a spring, isolator, or damper, especially where material properties are frequency-dependent. These include:- Engine mounts
- Metal and air springs
- Shocks
- Bridge expansion joints
- Damping mounts
- Rubber components
Custom Test Programs for Real-World Confidence
Our experts have years of experience developing custom testing programs that accurately recreate the specific stresses and duty cycles that occur during the life of a product or component. This consultative approach gives your team maximum confidence in final test results and accelerates your product development timeline.
