Testing Services

Investmech carries out several conformance tests in the laboratory. The tests are carried out according to user specified or international requirements.

Accelerated durability testing is a new technology in the market where time domain response reconstruction of field measured responses is carried out, and, with the aid of mission profiles and fatigue analysis an accelerated test performed. This enables Investmech to carry out a 100,000km durability test on a motor vehicle in approximately 22 days. This result in cost benefits and significant reduction of the safety risks of carrying out such a test. The technology used in the accelerated durability test is the reconstruction of field recorded strain and acceleration signals that on a dynamic test rig, consisting of servo-hydraulic actuators.

Investmech applies internationally accepted algorithms to characterise suspension units and polymers in terms of their damping and stiffness properties.

Due to Investmech’s experience in the field of metal fatigue and fracture mechanics, Investmech carries out tests to quantify the fracture toughness and S-N properties of materials.

Investmech carries out simple and complex measurements of which the following are typical examples:

1. Acceleration and strain measurements for time domain reconstruction of inputs on vehicles, load boxes, trucks, ships, large super structures, etc.
2. Noise, vibration and harshness (NVH) measurements and control on automotive vehicles, plants, structures, etc.
3. Acceleration measurements on man cages in mines to quantify whole body response, railway vehicles, etc.
4. Strain, acceleration and temperature measurements on high temperature pressure vessels, ladles, refractory, furnaces, steam pipes, etc.
5. Strain and acceleration measurements and control on pipes
6. Acceleration measurements on offshore oil rigs, aeroplanes, railway vehicles, etc.
7. Modal analysis and operational mode extraction (Synthol reactors, ships, pressure vessels, automotive vehicles, cellular masts, trucks, electric motors, crushers, electrode control systems, furnaces, steam and other piping, etc)

1. Four to six poster durability tests on vehicles, trailers, trucks.
2. Durability tests on components.
3. ROPS and FOPS testing.
4. Shaft steelwork accelerated durability testing.
5. Low temperature brittleness tests.
6. Thermal testing of exhaust pipes.
7. Durability testing of exhaust pipes.
8. Durability testing (roller fatigue, towing devices, six-axis response reconstruction tests).
