Vertical-type plate rack vibration isolation base

Abstract

The invention relates to a vertical-type plate rack vibration isolation base. The vertical-type plate rack vibration isolation base comprises a rib plate. Connecting plates are installed on the top of the rib plate at intervals, vertical-type installment bases are located among the connecting plates, and vibration isolation devices are connected to the vertical-type installment bases. A first web and a second web are installed at the two ends of the rib plate respectively, and a supporting plate is further installed on the second web. The vertical-type plate rack vibration isolation base is low in mass, and small in size and occupied area, effectively improves equipment using environment, can be applied to passive vibration reduction of ship mechanical equipment so as to improve vibration and noise reduction levels of the mechanical equipment and reduce weight of the base, and can be applied to vibration and noise reduction of other similar mechanical equipment.

Description

technical field [0001] The invention relates to the technical field of vibration reduction control, in particular to a vibration isolation base for a vertical plate frame of ship equipment. Background technique [0002] Most of the vibration generated by ship power machinery and equipment during operation is directly transmitted by the base to the hull structure and becomes structure noise. The installation of marine machinery and equipment on the hull structure generally relies on an intermediate installation component—vibration isolation base. The base structure of a ship is an important part of the sound transmission from mechanical equipment to the hull. Its impedance characteristics and matching relationship with the vibration isolation system directly affect the vibration isolation performance of the entire system. Improving the input impedance of the base structure can bring Come to the good vibration isolation effect of the base. [0003] According to the tradition...

Problems solved by technology

[0005] At present, the impact of the rigid base on the vibration and noise of the vibration-absorbing mass, the hinge support of the plate or rod, the joints of the structure (linear connection, angular connection, T-shaped connection, cross-shaped connection, etc.) A lot of research, this move brings high weight and large size at the same time, which directly increases the difficulty of the overall design of the ship

[0006] At present, the base and equipment generally adopt the connection method of "base panel, vibration isolator", that is, the installation method is to install the vibration isolator directly on the base panel. When it is applied to a vertical plate frame, it cannot be installed
