Experimental Study On Vibration Reduction Of Large-scale Industry Workshop

Power equipment universal existence in industry workshop, along with has used the long time or had not considered the influence of dynamic load during design, the equipment's vibrate will cause the workshop structure vibrating, The vibration can cause the structure to Produce the cracks and evenly destroy the structure, this is a very important question for the industry workshop. But, The workshoP structure which has power equipments often can't completely avoid vibration, the key is must control it in the scope which allowed.This article in view of some crushing plant main workshop structure vibration's concrete project example, through actual obtained the workshop structure dynamic performance on the spot, including crosswise and longitudinal vibrational frequency, mode of vibration, damping ratio, as well as the equipment revolves when the workshop structure's vibration linear displacement, to transform the equipment to provide the essential data. Carries on the mechanical analysis using finite element software ANSYS to the workshop structure, before obtaining the workshop structure dynamic performance and the equipment foundation transformation, the workshop structure vibration linear displacement and with the measured data contrast, examines the finite element model the establishment and the computation accuracy, after transforming the workshop structure's vibration linear displacement carries on the predict that provides the technical basis for the equipment foundation's transformation. After the transformation, carries on the scene dynamic performance test to the structure, examined the power equipment foundation transformation antivibration effect.Finite element analysis and experimental results show that modification of the equipment based on a good damping effect, achieved the expected goal, this research provides the industry workshop structural design and vibration plant transformation for a useful experience.
