Abstract: The phase noise of an oscillator is generated by serious deterioration in a vibration environment, and concerned due to the physical properties of multi-disciplinary integration and application value in electronic systems. Along with the development of scientific concept on mechanotronics, it becomes possible to study the noise in a signal tuning mode and to explore its unique physical properties in a vibration environment. Thusly, the tuning principle of phase noise deterioration under vibration conditions is analyzed according to the working principle of crystal in this paper. A new method of physical characterization of crystal oscillator phase noise and vibration deterioration characteristics are put forward. In addition, the measurement system of oscillator-phase noise is built. The influence of various input conditions on the electrical properties of the crystal is studied based on quantitative experimental data, and the corresponding algorithm is compiled to solve the mathematical problem. The nonlinear mathematics relationship of the problem is obtained. Finally, the mechanotronics analysis ideas and physical characterization methods are verified by experimental data, and the robust vector of crystal oscillator module in a vibration environment is calculated.
