Laser vibrometry has established a firm place in the automotive sector over the past few years. This non-contact process is used at Porsche Engineering to investigate and improve the dynamic behavior of valvetrains during engine development. By using laser vibrometry at an early stage of development, Porsche Engineering is examining the valvetrain for kinematic properties, dynamics, and stress in the desired RPM range.The necessary valvetrain development modifications were targeted and evaluated on several projects through the use of laser vibrometry, and thus avoided costly and time-intensive development loops.
