Simplifying the complex vibration reduction design process makes sense and helps engineering to improve efficiency. The passive vibration reduction system of electronic equipment is simplified and equivalent to a single degree of freedom damped forced vibration system, and based on reasonable simplification, equivalence and approximation, a complete theoretical analysis model and mathematical calculation model of vibration damping of electronic equipment are established by replacing the complex nonlinear vibration theory with simple linear vibration theory. The vibration reduction characteristics of vibration damping and the factors affecting the vibration reduction effect are studied and analyzed, the influence of damping on resonant frequency and resonant vibration transmission rate is given, and the mathematical model for evaluating the vibration reduction effect of random vibration excitation is established. Combined with engineering experience and empirical formula, the general process and key design process of vibration reduction design suitable for engineering application are given. Taking the vibration reduction design of an electronic equipment as an example, the complete process of vibration damping system design is demonstrated, which provides an example reference for engineering design.
