Durability and life cycle testing

Exova has been providing structural and mechanical cyclic testing for over 20 years. The structural and mechanical testing facilities have supported the automotive, commercial truck & bus, off-highway and military industries.

Exova’s structural testing provides the facilities and equipment to test individual components, sub-systems and fully operational systems. Operational service environments subject components and systems to complex loading conditions in a laboratory environment.

Full vehicle simulations and Proving Ground Testing require longer duration test times. Current design times and limited funding minimizes the number of full systems available for testing. Laboratory testing allows for multiple components or sub-systems to be evaluated at compressed time to meet the development schedule.

Load and displacement parameters from Road Load Data Acquisition (RLDA) or computer model predictions can be used to develop single or multi-axial inputs block cycle or constant amplitude structural durability tests.

Exova can also integrate environmental conditioning & other auxiliary thermal, pressure and electrical inputs if required during the structural durability testing. Exova’s structural & mechanical test facilities utilise hydraulic, pneumatic, robotics and electrical equipment to support these test activities.
