Mechanical - Component Testing, Dynamic Load and Fasteners
Component Testing
Testing components takes many forms depending on the application and the conditions present in service. TCR routinely tests components under fatigue, vibration, shock, pressure, high and low temperature, humidity, solar, corrosion, impact, hydro-static pressure and altitude conditions. Test capacity vary from small (several inches in size) to large (vehicle size). Test fixtures can be made in-house from 3D drawings or FE models.

Frequently tested components include, automotive parts and assemblies (i.e. Axles, engine cradles, transmission shafts, shock absorbers, doors, locking enclosures, connecting rods as engine mounts and crankshafts) electronic displays, communication devices, packaged products, pressure vessels, pipes, and building products such as fascia and structural products. Aerospace components in particular electronic devices and landing gear assemblies are also tested.

Dynamic Loading

Dynamic loading takes on many forms: impact, vibration, shock, fatigue, high strain rate to name a few. TCR is capable of performing many forms of dynamic tests on specimens, prototypes and assemblies.

Fasteners - Wedge, Axial, Proof Load and Torque

Fasteners of all sizes used in every application are critical to the integrity of structures and finished components. In addition to dimensional, chemical composition, and metallurgical properties, Mechanical Testing is of paramount importance in determining compliance with specifications and fitness for purposes.

The wedge tensile strength of a hex or square-head fastener, socket-head cap screw, or stud is the tensile load that the product is capable of sustaining when stressed with a wedge under the head. The purpose of this test is to obtain the tensile strength and to demonstrate the head quality and ductility of the product.

Axial tension of fasteners are tested in a holder with a load axially applied between the head and a nut or in a suitable fixture.

Proof Load
Proof Load testing of a nut is assembled on a hardened threaded mandrel or a test bolt using the tension or compression method. A specified proof load is applied for the nut against the nut. The nut should resist this load without stripping or rupture and should be removable form the test bolt or mandrel by hand after the load is released.

The most common way to estimate clamping force is to observe the amount of torque applied to the fastener. This procedure assumes that the relationship between torque and tension is known. The most common measurement tools are hand held torque wrenches.
