Abstract
The invention discloses a system and a method for vibration testing of an elastic template. The elastic template is a shell-shaped piece with a circular-arc-shaped section, and a larger end of the shell-shaped piece is an open end. The system for the testing comprises a vibration generating device and a fixing mechanism used for fixing the periphery part of the open end of the elastic template on the vibration generating device in an enclosing mode and connecting the periphery part of the open end of the elastic template to the vibration generating device in a rigid mode. The method for the testing comprises: fixing the periphery part of the open end of the elastic template on the vibration generating device in the enclosing mode, and connecting the periphery part of the open end of the elastic template to the vibration generating device in the rigid mode; and starting the vibration generating device to carry out the vibration testing. The system for the vibration testing of the elastic template is simple in structure, easy to operate, capable of carrying out the vibration testing under the conditions of an actual working state of a high-fidelity simulation elastic template, accurate in testing results and not capable of damaging the structure of a tested piece.
