Placement study of composite vibration isolation system for machinery equipment

In traditional vibration isolation and placement studies, vibration participation of foundation is often ignored, and optimizations are focused on the improvements of isolated object and isolation system. In this paper, clamped thin plate was considered as the foundation, and machinery equipment vibration isolator foundation was proposed as a composite vibration isolation system. Based on the theory of mechanical four-pole connection, transmitted force from equipment to plate was derived, and the intermediate variable was the displacement admittance of contact points (isolators) on the plate. To peruse the optimal placement, a novel procedure has been programmed, and two cases of arrangement direction have been involved. This study could give a lot of inspiration for vibration isolation and placement strategies of engineering equipment so that extended researches based on this could be performed.
