A vibration measurement sensor (3) adapted to measure the vibrations formed on a test object (O) with moving mechanical systems, at least one noise measurement sensor (4) adapted to measure sound intensity and/or particle velocity and/or sound pressure in at least one direction, i.e. on one axis, and a vibration and noise mapping system (1) that is adapted to control the vibration measurement sensor (3) and the noise measurement sensor (4), to provide the vibration and acoustic performance data of the test object (O) according to the data obtained from these units (3, 4) and to identify the areas on the test object (O) that are problematic or need to be studied further in order to improve vibration and acoustic performances thereof, and to control the operation of test objects (O) such as moving mechanical systems under different conditions.

A testing device for testing a drive train or components within a marine propulsion system is provided and includes a first disk with a plurality of first disk depressions that faces a second disk with a plurality of second disk depressions. The first disk and the second disk are secured relative to each other so that they define a space, and a seal at outer edges of the disks is in fluid communication with the space. One of the first disk and the second disk is secured to a driven shaft. Upon rotation of the driven shaft, a load is produced due to shearing of fluid between the disks, yet no thrust is produced.

A diagnostics and maintenance tool can be used for performing diagnostics and maintenance of automotive, farming, construction, trucking, recreational and aviation vehicles & equipment. The diagnostics and maintenance tool can be used to measure distance traveled and pressure applied to brake, clutch and acceleration pedals, for example. The tool can reduce labor costs by reducing the time it takes perform certain diagnostic and maintenance activities. The tool can increase customer satisfaction by increasing accuracy and providing quantifiable data versus just going off of “human hunches.” The tool can reduce misdiagnoses by a technician who does not have to rely on “guesswork” or “process of elimination” for certain tasks. The tool may attach between a support and a component where distance traveled and applied pressure is to be measured. The tool may be pre-programmed to apply a known pressure or distance or may be remotely operated.

Methods and systems for testing an aircraft in-flight are described herein. The method can include receiving a test deck including one or more test cards, with an individual test card including an ordered list of points. For an individual test card, points of the ordered list of points can be performed, a status for the performed points of the ordered list of points can be assigned, a current fuel value for the aircraft can be received, and the current fuel value can be compared to an expected amount of fuel required to perform the remaining test cards. In response to the comparison indicating that the current fuel value is not sufficient for the remaining test cards, the method can include modifying the test deck at least until the current fuel value is sufficient for executing a subset of remaining test cards.

A vehicle is received in a stationary controlled area of a controlled testing environment. Simulation inputs corresponding to a simulated scene are generated and transmitted to the vehicle. The vehicle applies torque in response. A vehicle control mechanism of the controlled testing environment, such as a chassis dynamometer, a motorized treadmill, or a lift, keeps the vehicle within the stationary controlled area during the test despite the torque applied by the vehicle. A path of the vehicle within the simulated scene is determined based on the applied torque, based upon which the vehicle's navigation system is calibrated.

A simulation system, device, and method for testing a train management system on a road-rail vehicle is provided. The simulation system includes: a brake pressure simulation device adapted to be connected to a first input of the train management computer, the brake pressure simulation device including at least one circuit configured to output signals representative of at least one brake pipe pressure; and a speed simulation device adapted to be connected to a second input of the train management computer, the speed simulation device configured to detect a speed of the road-rail vehicle and output signals representative of the speed. Also disclosed is a simulation system wherein the at least one circuit of the brake pressure simulation device is configured to have variable resistances.
