STRUCTURAL DURABILITY & FATIGUE TESTING

Meeting Your Needs Through Customized Structural Lab Testing

Structural durability and fatigue testing is performed by subjecting a test sample to the load conditions it will experience during its service life. This testing is typically performed early in the product development process to identify any design deficiencies prior to releasing the product for production. It is also commonly used as a qualification test for component selection or final product validation. 

When you work with us, you gain access to an assortment of hydraulic actuators and an MTS FlexTest® controller for customized structural lab testing. With this test equipment, we have the ability to perform a broad range of test control options from simple square wave and sinusoidal inputs to full simulation of complex field data with up to four independently controlled actuators. Our FlexTest controller has he ability to independently control up to four different hydraulic actuators, allowing up to four different test loads to be applied to the test sample simultaneously.

VIBRATION TESTING

Utilizing the MAST System for Sinusoidal, Random & Field Simulation Tests

Six degrees of freedom motion to produce a number of tests including sinusoidal, random, and field simulation tests. Our MAST system is ideally suited for testing ground based vehicle or machine components to evaluate how they will respond to vibration anticipated during operation, or transit, and to verify how the product is expected to survive through its entire life. 

This testing is commonly performed on machine or vehicle components that will experience vibration loads throughout its service life. The test sample is secured to the platform of the shaker table using a test fixture or mounting system that is representative of its end-use installation.

CUSTOM TEST STAND DEVELOPMENT

Embracing Innovation Through Custom Testing Configurations

We believe in supporting innovation. We work directly with you to develop, design and build custom test stands needed to support unique configurations of custom hydraulic cylinders, power train components and other mechanical systems. It is our goal to work directly with our clients one-on-one to advance industry.

HYDRAULIC CYLINDER TEST

PAMI’s hydraulic cylinder testing capabilities include:

  • Cylinder Friction Test as per SAE J1334
  • Cycle Test Procedure as per SAE J1334 
  • Impulse Endurance Test as per SAE J1334
  • Drift Rate Test (Piston Seal Leakage) per SAE J1336
  • Proof Pressure Test (apply 200% rated pressure with piston mid-stroke) 

The hydraulic cylinder test system can be configured for testing single-acting and double-acting hydraulic cylinders. 

Hydraulic Power Unit

PAMI’s hydraulic cylinder test equipment is powered by a hydraulic power unit (HPU) capable of 20 GPM at 3000 psi, sized for testing hydraulic cylinder with rated (working) pressures of 3000 psi. The HPU has an 80 Imperial Gallon fluid reservoir that can be filled with Client specified hydraulic fluid and maintained at temperatures up to 80°C. 

Cycle Test

The hydraulic cylinder cycle test equipment is capable of testing cylinders with inner diameters up to 4.0”. The fixture can be configured for testing 1, 2, or 3 cylinders simultaneously. When testing 1 or 2 cylinders, the test equipment can accommodate cylinders up to approximately 56.0″ mid-stroke length (or roughly 41″ retracted length). The maximum cylinder length for testing 3 cylinders simultaneously is approximately 23″ mid-stroke length (or roughly 17″ retracted length). With many different cylinder designs, it is recommended that the test cylinder specs be reviewed by PAMI engineers to verify that it fits the test setup.

Impulse Endurance Test

PAMI’s impulse endurance test fixture is adjustable to accommodate a wide range of cylinder
sizes. The fixture is used to rigidly secure up to three test cylinders at their mid-stroke length, as
required for the test. It can accommodate hydraulic cylinders with mid-stroke lengths up to 60 inches.

PAMI has an array of instrumentation and data acquisition equipment that is used to monitor
and record various parameters throughout testing. Monitoring these parameters allows us to ensure accurate control and provide test records to the client.

Shortened testing cyle.

Compress lengthy testing into a shortened timeline allowing for quicker results, improved efficiencies and faster to market. Durability and fatigue testing is an economical and convenient alternative to traditional methods requiring less time than field testing which in turn gets products to market faster.

Prevent over-design and save on unnecessary material costs.

One of the primary advantages of utilizing durability testing is its ability to prevent over-design, which, in turn, helps save on unnecessary material costs. Traditional design methods often lean toward a conservative approach, leading to designs that are heavier and bulkier than required. By conducting detailed simulations, engineers can precisely determine the structural and functional requirements of a component or system, eliminating excess material usage.
