In order to solve the technical problem that the vibration isolation technology of on-board environmental equipment is difficult to quantify,a set of design and calculation methods for vibration isolation of on-board equipment was proposed.In this method,the vibration isolation requirements are first put forward according to the characteristics of the on-board equipment,then the vibration isolation platform of the on-board equipment is preliminarily designed by solving the corresponding frequency by combining the second-order linear non-secondary equations,the stress conditions that must be met by the on-board equipment are determined again,and finally the displacement,acceleration and steady-state stress level of the on-board equipment are calculated by using the finite element method.In this paper,taking the vehicle-mounted vacuum device as an example,the vibration isolation platform is designed according to the above theory,and the feasibility is verified by finite element method,and finally it is shown that the designed vibration isolation platform meets the requirements of vibration characteristics,and the method can be applied to the development of vibration isolation platform for vehicle-mounted equipment.
