Multi-Specimen Fatigue 16

16-Specimen Capacity

Multiple test specimen sites with up to 100 mm height and 38 mm spacing between specimens are driven by a lower spider connected to the upper linear motor. This design effectively transmits the upper motor’s motion to each specimen. Testing can be run using the standard sine waveform or users can define their own motion profiles up to 100 Hz.

High Performance Linear Motor

With the highest dynamic capabilities and proven reliability, the ElectroForce linear motor delivers precise and controlled motion to all 16 specimens. Its reliability from frictionless moving magnet design is perfectly suited for the millions to billions of test cycles of demanding accelerated fatigue test programs. This reliability is backed up by the industry’s only 10-year motor warranty.

Independent Force Measurements

Force sensors are individually connected above each of the 16 specimens. These are monitored by the WinTest test control and acquisition software which records the cycle count of each specimen failure.

Precision Specimen Preload Adjustments

Each specimen station includes a thumbscrew for adjusting the mean position of the upper specimen attachment point. With 20 mm of travel, precise guidance, and fine threads, users can accurately position each specimen to apply specific mean preloads prior to dynamic testing.

Tool-free Specimen Preload Clamps

This novel clamping mechanism allows users to securely clamp each specimen at an adjusted preload. It eliminates the need for external tools and minimizes both vertical and lateral motion during locking.

Mechanical Overtravel Stop

This mechanism physically prevents motion beyond desired levels within the full 25 mm range of travel, eliminating unintentional specimen overload and giving the user peace of mind.

Temperature Controlled Fluid Bath

The temperature-controlled fluid bath enables dynamic testing within fluid environments up to 45 °C. Positioned below the multi-specimen assembly, the bath allows users to lower mounted specimen into fluid prior to test initiation.

Auto-Fill Bath

Designed to avoid the inconvenience and temperature variations caused by the user periodically manually refilling the bath during long-term fatigue tests. Upon fluid loss, a float valve releases fluid into the rear auxiliary bath and slowly gravity fed into the main bath preventing temperature fluctuations which may adversely affect temperature-sensitive specimens.

Accessible and Viewable Samples

Each of the 16 specimens are positioned to avoid obstruction by the columns of the test frame. This makes both test setup and optical monitoring easy and free from this obstruction.

Convenient Specimen Fixture Mounting

Each site includes an upper and lower threaded connection for user-designed fixturing. Detailed drawings, including these attachment points, are provided to the user upon purchase.

3300 Series III Load Frame

The MSF16 configuration is built upon the industry leading 3300 Series III instrument and load frame. MSF16 users enjoy multiple user conveniences such as electric lifts, tool-free locks and system status indicator lights. When desired, the MSF 16 accessory can be removed to leverage the single-specimen test capabilities of the stand alone 3,000 N and 25 mm ElectroForce 3330 instrument.

3330 MSF16 with 40 N Force Sensors

3,000 N Electrodynamic Motor with 25 mm travel and 40 N Force Sensors.

The 40 N force sensors offer lower levels of force measurement but tolerate less fixture mass than the 100 N configuration.  Recommended for specimen fixture masses less than 20 grams.

3330 MSF16 with 100 N Force Sensors

3,000 N Electrodynamic Motor with 25 mm travel and 100 N Force Sensors.

The 100 N force sensors accommodate more force and more specimen fixture mass than the 40 N sensor configuration with slight trade-off of minimum force measurement. Recommended for specimen fixture masses less than 75 grams.
