Structural Design Method for Shock-resistant Protective Shell of Test Equipment

Abstract

The invention relates to a design method of a shock-resistance protection shell structure of test equipment, in particular to a design method of a shock-resistance protection shell structure of test equipment. The invention solves the problems that the traditional design method of the shock-resistance protection shell structure of the test equipment is not beneficial to uniforming design methods of the test equipment to cause that the design period of the test equipment is prolonged and the design cost is increased. The design method of the shock-resistance protection shell structure of the test equipment comprises the following steps of: (1) designing and determining a shape structure of the shock-resistance shell; (2) quantitatively determining the buckling speed of an inner cylindricalshell, the yield speed of an outer cylindrical shell and the rupture limit of a circuit board; (3) determining the top cover thickness of the inner cylindrical shell, the top cover thickness of the outer cylindrical shell, the thickness of a buffering material and the thickness of an encapsulating material; (4) designing a buffering structure resistant to large shock; and (5) designing an anti-slabbing structure. According to the invention, the design methods of the test equipment can be ensured to tend to uniform while facing to different test environments.

Description

technical field [0001] The invention relates to a design method for an anti-shock protection structure of testing equipment, in particular to a method for designing the structure of a testing equipment anti-shock protection shell. Background technique [0002] In recent years, with the continuous development of the aerospace industry, in order to enable researchers to obtain reliable test data in typical high-overload environments such as spacecraft launch and recovery, test equipment must take special protective measures. The device is created from this. The most notable feature of the shock resistance test equipment is that it can withstand high impact, launch and landing overloads. Due to the use of protection technology, the test equipment can still successfully obtain data in very harsh environments. At present, many scientific research institutes at home and abroad have carried out the development of anti-high impact testing equipment. However, due to the complexity ...
