The key role and advantages of vibration testing in evaluating the durability performance of automotive components
The vibration test bench can simulate the dynamic response of vehicles under road excitation, and conduct a series of controllable vibration simulations in the laboratory to test whether automotive components can withstand the impact of vibration environment during transportation, assembly, and use during their lifecycle. This can help detect electrical short circuits, loose fasteners, seal failures, and cracks as soon as possible.
