Vibrations On Machine Foundations

Product Description

Vibrations On Machine FoundationsTechnical description ofVibrations On Machine FoundationsAn indispensible element of machine design is targeted reduction of vibrations. An elastic, vibration insulating installation of the machine avoids the transmission of harmful vibrations to the surroundings. Thecan be used to investigate the problems of foundations and vibration isolation using a practical example. To do this, vibrations are generated and measured on a foundation. Springs are then used to try out different tunings and vibration absorbers are used to investigate absorption effects. This is installed on a foundation using springs and dampers. The foundation represents the surroundings and can be used to measure the effectiveness of the vibration isolation. Additional helical springs connect the foundation to the actual frame of the trainer. This double vibration isolation, combined with the high fixed weight of the frame, guarantees vibration-free laboratory operation, even under unfavourable experimental conditions.Specification ofVibrations On Machine Foundations Representing and investigating vibrations on machine foundations Vibration generator generates vibrations by imbalance Vibration-free operation due to additional vibration isolation of foundation 2 brushless high power servo motors as the machine drive Eccentricity, rotation frequency, direction of rotation, phasing and frequency ratio adjustable Variable arrangement of vibration absorbers for absorption of vibrations Vibration measurement using acceleration sensors Inductive position sensor records the eccentricity of the imbalance masses Software with control functions and data acquisition via usb under windows vista or windows 7 Piston compressor for use as alternative real vibration generator Technical dataVibrations On Machine FoundationsDrive motors Max.
