For Accelerated High-Throughput Fatigue Testing
Instron ElectroPuls 16-Stations Testing Systems.
A key technical innovation is the ability of the central digital controller to manage the complex, independent loading profiles of all 16 stations concurrently. Each station operates as a truly independent test machine, capable of running unique force, displacement, or strain control programs, while the system ensures minimal electronic crosstalk and maintains the high waveform fidelity characteristic of the core all-electric technology across every single test point.
The system provides a powerful solution to the laboratory space constraint by significantly maximizing the number of tests run per square foot. Furthermore, by consolidating the power and control infrastructure, the system offers substantial cost-of-test savings compared to purchasing and maintaining 16 individual dynamic testing machines, making high-volume, statistical fatigue analysis highly accessible and efficient for industrial and contract testing laboratories.
Laboratories requiring high-volume fatigue data (e.g., N=100 or more) are hindered by the massive time and space investment needed for numerous single-station machines. The 16-station system solves this by running up to 16 tests in parallel, drastically increasing the data acquisition rate per day and minimizing the required floor space.
Running multiple tests simultaneously is often compromised by electronic interference or data crosstalk between independent channels, leading to questionable results. The system's advanced digital control and shielded electronics are specifically engineered to maintain the independence and high signal-to-noise ratio of each of the 16 load channels.
The high capital expenditure and maintenance overhead associated with purchasing and servicing multiple full-sized dynamic machines makes large-scale statistical testing prohibitively expensive. This platform provides a cost-effective alternative by utilizing a single shared control, power, and HPU-free infrastructure to service all 16 test points.
Managing and organizing the large, complex data streams generated by numerous simultaneous tests can be logistically challenging and prone to manual data association errors. The unified software platform provides centralized data logging and management, automatically associating the high-speed data from each of the 16 stations with its corresponding specimen ID.
Researchers testing materials requiring rapid assessment of lot-to-lot variability or quality control are severely slowed by the sequential nature of single-station testing. The parallel design allows for the immediate statistical comparison of material batches or component designs, accelerating quality release decisions and R&D iterations.
When testing medical devices or sensitive components in non-ambient conditions (e.g., bio-bath or low temperature), the cost and complexity of providing environmental controls for numerous individual chambers are significant. The high-density design facilitates the use of shared or modular environmental chambers that cover multiple test stations, simplifying the environmental control setup.
Maintaining precise waveform synchronization and phase control across multiple stations is often necessary for accelerated fatigue protocols, but technically complex to implement. The centralized digital controller ensures precise, synchronous triggering and execution of complex waveforms across all active test channels, enabling highly controlled, accelerated protocols.
The system is designed to allow for independent control and failure detection at each station. This means that if one specimen fails, the remaining 15 continue their test sequence uninterrupted, mitigating the risk of losing all ongoing test data due to a single component failure.
