Measuring Engine Developments In Real Time

摘要

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. AICON 3D Systemsrnhas developed the optical measuring system EngineWatch to measure engine movements precisely by using its high-speed TraceCam F camera.rnThe camera uses a CMOS sensor, flash, and an image analysis processor. TraceCam Frnfeatures shutter speeds of just a few microseconds that are necessary for long-duration tests and ensures the system is robust and stable over time. Mounted on a fixture, the Trace-Cam F camera focuses on the engine block and detects relative movements of two solid reference targets placed on the engine blockrnand on the car body. The position of the camera to the engine block does not need to be stable as EngineWatch recalculates its position continuously using the reference targets, and so camera movements cannot influence the measuring results.
