  1.Introduction

Mechanical Environment Testing refers to all kinds of tests against products based on dynamic mechanics and static mechanics in all kinds of mechanical environments. Acceleration, speed, displacement, kinetic energy are all the most basic physical elements.

Mechanical Environments include:
 Natural condition: natural wind(vibration and shock), surface vibration(seismic resistance of buildings),etc;

Storage condition: fall during transportation(vertical shock), stacking(vertical pressure), clamping during

transportation(horizontal pressure), etc.;

Transportation condition: vibration in water transportation, road transportation, railway transportation and air                                                                       transportation(sine and random), shock, collision, etc.

Inherit properties: frequency response characteristics of components(natural frequency and fatigue property)

Through all kinds of mechanical environments, mechanical environment test can evaluate products’ adaptability of mechanical environment and structure wholeness under specific mechanical environment, which is a necessary method to solve the problem of quality reliability of products and packages.
