Abstract

The invention discloses equipment for evaluating the static displacement and deformation of a vibration insulating foundation of a steam-turbine generator, and belongs to the technical field of design of a spring vibration insulating foundation of the steam-turbine generator. The equipment comprises a finite element analysis module, a parameter calculation module, a result evaluation module and an output module, which are sequentially connected and perform processing by utilizing a computer system. The invention also discloses a method for evaluating the static displacement and deformation of the vibration insulating foundation of the steam-turbine generator. According to the equipment, model data obtained by a foundation designer is delicately post-processed, key displacement and deformation indexes with great influence on the running of a machine set are extracted after calculation, and whether the static displacement and deformation of the vibration insulating foundation are qualified or not is evaluated. Moreover, the method can be easily implemented in mathematical calculation software such as Excel or Matlab, and is low in calculation requirement and high in operability.

Description

technical field [0001] The present invention relates to the design of a spring vibration isolation foundation of a turbogenerator, in particular to a device and method for evaluating the static displacement and deformation of the vibration isolation foundation of a turbogenerator. Background technique [0002] The vibration isolation foundation of the turbogenerator serves the turbogenerator, and the turbogenerator manufacturers usually require the vibration isolation foundation to have three aspects of performance: 1. The dynamic response of the vibration isolation foundation is within the allowable range; 2. The vibration isolation foundation should have sufficient strength to cope with special situations such as earthquakes and short circuits; 3. The vibration isolation foundation should have sufficient rigidity to avoid excessive displacement and deformation. The reason why there is a requirement for the stiffness of the foundation is that the deformation of the foundati...
