Non-contact high speed monitoring of wheel motion in vehicle dynamics testing                   WheelWatch Test System       on a moving vehicle or in a test station       measuring of wheel clearance       accurate measurement of all wheel parameters including track, camber inclination, spring travel, and steering angle       simultaneous monitoring of several wheels or axles Advantagesvehicle dynamics testing without mechanical connection between sensor and wheelself-referencing to vehicle coordinate system in real timevery short setup timeextendable for other static and dynamic and measuring tasksCase studiesFrom test bench to test track - Vehicle dynamics testing at ika Aachen Functional principleWheelWatch is built around a high speed digital camera consisting of a high resolution CMOS sensor, an integrated high performance flash and an image analysis processor.The digital camera features extremely short shutter speeds of just a few micro-seconds that are necessary for vehicle dynamics testing. It also ensures the system is robust and stable over time.WheelWatch provides data at a frequency of 490 Hz, ideal for studying and optimizing static and dynamic chassis parameters.     System components:MoveInspect basic systemper axle 2 MoveInspect HF cameras and 2 CFK wheel adaptersmounting frameaccessory set including targets, syncbox for 1-4 cameras, and controlling computer with WheelWatch softwareSystem parameters:Position accuracy: X, Y, Z± 0.1 mmAngular accuracy± 0,015°Measurement volume1,000 mm x 1,000 mm x 500 mm (40“ x 40“ x 20“)Distance camera /wheel adapterapprox. 0.5 m (20“)Measurement range (track/camber)± 45°Spin angle rangeunlimitedMax. acquisition frequency500 HzWheel adapter:Materialcarbon fiberDiameter400 mm (16”)WeightTargetsANCO on retro reflective film High Gain 7610Camera:Type of cameraHigh speed CMOS camera (MoveInspect HF)Resolution1280 x 1024 pixelsMax. afrequency500 HzExposure time10 µs - 100 µsLensHigh performance lens, f=10 mm, minimal distortionFlashHigh performance LED ring light, 10-100 μsData transmissionTCP/IPSynchronizationDigital time stamp / Master/slave mode, Clock / Enable IN/OUT (TTL o. 20 mA Loop)Power supplyTest drive: 12 Volt vehicle power system; test station: 90 - 240 VoltSoftware:camera calibrationaxle calibrationdetermination of reference pointstransformation in vehicle coordinate systemdata transfer via data file, analog or digital (TCP/IP)calculation of axle and wheel parametersControlling computer:Test driveNotebook (Microsoft ® Windows ® 7 (64 Bit))Test stationDesktop computer (Microsoft ®Windows ® 7 (64 Bit))
6D measurement of engine motion in vehicle testing                    EngineWatch Test System      6-DOF measurements of movements in real time     high measuring frequency of up to 490Hz at unlimited measuring time     measuring results are shown as absolute values in vehicle coordinate system     used for test drive and test station In vehicle development, exact information about engine-to-body clearance is necessary to ensure an optimal design of the available space. For example, the engine must not collide with other parts in the engine bay when the driver changes gears or deals with difficult driving maneuvers. Advantagesshort setup timehigh accuraciesno mechanical connection between sensor and engine blockcamera mount does not need high stabilityhigh speed camera also applicable for motion analysis of any other object, i.e. not only for vehicle testing applicationsextendable for other static and dynamic measuring tasksFunctional principle      AICON's measuring system EngineWatch is specially designed for Vehicle Testing. EngineWatch is built around a       high speed camera which consists of a high resolution CMOS sensor, an integrated high performance flash, and an image analysis processor. The camera features extremely short shutter speeds of just a few micro-seconds that are necessary for long-duration tests. It also ensures the system is robust and stable over time.HardwareSystem components:MoveInspect basic system with high speed cameramounting frameaccessory setsyncbox for 1-4 cameras (cascadable)controlling computer with EngineWatch softwareone set of coded targets (ANCO-code)thereof 50 on magnetic mountcalibration panel with transportation caseTechnical specifications:Operating systemMicrosoft ® Windows ® 7 (64 Bit)Power supplytest drive: 12 Volt vehicle power system test station: 90-240 VoltMax. acquisition frequency500 HzSynchronizationDigital time stamp / Master/slave mode, Clock / Enable IN/OUT (TTL o. 20 mA Loop)EngineWatch data setX, Y, Z, alpha, beta, gamma, number of picture, time stamp (ASCII-format)Measuring volume (X, Y, Z)1,000 mm x 1,000 mm x 500 mmAccuracy XYZ / angular accuracy±0.1 mm / ±0.015° Technical data subject to change without notic
MoveInspect HF Test SystemMoveInspect HF captures dynamic processes three dimensionally and analyses them regarding geometric changes. The high-end version is able to conduct tests without a time limit.
