A method for monitoring a shock strut may comprise measuring a first shock strut pressure, measuring an ambient temperature, measuring a shock strut stroke, measuring a second shock strut pressure, and determining a servicing condition of the shock strut based upon the first shock strut pressure, the ambient temperature, the shock strut stroke, and the second shock strut pressure, wherein the servicing condition indicates whether it is desirable for the shock strut to be serviced with at least one of a liquid and a gas. The first shock strut pressure and the shock strut stroke may be measured before the takeoff event with a weight of an aircraft supported by the shock strut.

The disclosure provides a vehicle excitation advice. The vehicle excitation device that excites a vehicle having a plurality of wheels includes a plurality of excitation machine bodies on which the wheels are placed, respectively. The excitation machine body includes a front shaft and a rear shaft on which the wheels are placed at intervals in the in the front-rear direction of the vehicle, and an actuator (hydraulic actuator) that excites vibration to the wheels by moving at least one of the front shaft and the rear shaft in the front-rear direction. The front shaft is inclined such that the inner end portion of the front shaft in the left-right direction of the vehicle is located closer to the front of the vehicle than the outer end portion of the front shaft in the left-right direction of the vehicle.

In one or more embodiments, a double damper is disclosed that may be used in an automotive suspension system. In one embodiment, a double damper includes a first damper having a first piston rod, a first gas chamber, a first compression chamber, and a first rebound chamber. The double damper further includes a second damper having a second piston rod, a second gas chamber, a second compression chamber, and a second rebound chamber. The first damper and the second damper are connected via a sleeve from which the first piston rod and the second piston rod extend at opposite ends.

A system and methods for stabilizer mat testing comprising a compressible material element and platen elements. Two stabilizer mats are positioned on opposing surfaces of the compressible material element and located between the platen elements. A force is supplied to the test system, i.e., a fluid supplied by a fluid supply component to the compressible material element, a load supplied by a load supply component to the compressible material element, or both. Displacement measurements from the stabilizer mat are obtained and evaluated. Stabilizer mat testing may be a standardized method used to validate design and manufacture, to test a simulated use that may occur in the field, to monitor life cycle, or to certify performance.

Disclosed herein are system, method, and computer program product embodiments for detecting potentially unsafe wear levels in vehicle suspension systems. An embodiment operates by receiving acoustic signals of a vehicle suspension system, processing, the acoustic signals to generate training data, training a predictive learning algorithm to generate a predictive wear model and classifying the processed acoustic signals to indicate wear levels of one or more components of the vehicle suspension system. The trained predictive wear model subsequently predicts wear levels of the vehicle suspension system for notification to a cloud-based repository. Fleets of driverless vehicles may continuously monitor wear levels for timely maintenance before failure occurs.
