Structural durability and fatigue testing is highly significant for a vehicle’s life expectancy. This involves assessing the integrity of critical components such as the body construction, chassis, damping systems, axles, powertrain mounts, and other assemblies. A key focus is understanding how various environmental conditions — like temperature, humidity, and and sunlight — affect the vehicle’s structural integrity.
During testing, a vehicle has to withstand typical mechanical loads encountered in operation over a specified simulated lifetime. Failure in the form of fatigue, incipient cracks or degradation is not acceptable.
Before running real-world field tests in dedicated proving grounds, the validation of a vehicle’s structural integrity is conducted as a full simulation on a PC and as tests in automated test facilities in durability labs. Here, road load data is reproduced by actuators.
Get the complete toolset in place – from lifetime fatigue analysis based on FE models to measurement and data acquisition perfectly suiting mobile in-field, lab and bench testing, to powerful software for desktop and server for analyzing your data from real-world physics and correlating with simulation. All with the goal that your whole team gets a rapid workflow from design towards sign off.
Orchestrate and accelerate your validation workflow – simulation and physical testing (measurement in field, lab and bench). Focus on your validation data flow, simplify steps and de-risk your project.

Integrate the best fit hardware combinations from different vendors in your overall testing solution with technologies such as EtherCAT, PROFINET, ASAM XCP-on-Ethernet or a simple API:
A Structural Durability Lab Testing Assessment is one of the last stages before a vehicle prototype can be released onto the market. To create structural test programs covering true market requirements, hydraulic, pneumatic and electric actuators, vibration tables and climatic chambers are used.
An operation profile defines the conditions to be monitored but also the target damages of the accelerated testing. In the lab, mainly strain and force-based measurements are used to characterise loads under replayed real-world operating conditions and calculate resulting accumulated fatigue damage.
To authentically imitate the road in numerous types of dynamic and static tests, different loads applied to the system under test are reproduced:
In Road Load Data Acquisition (RLDA), the vehicle is equipped with additional sensors: Strain gauges (SG), acceleration sensors, string potentiometers, special measuring wheels on one or two axes for force and torque measurement, GNSS/GPS/IMU sensors for position and kinematics, as well as video cameras for recording the driving situation.
