Abstract

The invention provides a spring energy storage type horizontal impact test stand which comprises a base, a waveform generator, a guide rail, an impact table for fixing an experimental article and a catapulting mechanism. The catapulting mechanism comprises a push plate, a spring pull rod, an installing plate, an energy storage spring, a compression air cylinder, a locking mechanism I and an air cylinder pull rod. The guide rail axially parallel to the test stand is arranged between the waveform generator and the installing plate of the catapulting mechanism. The push plate is installed on the guide rail. The impact table is installed at the portion of the guide rail located between the push plate and the waveform generator. One end of the spring pull rod is fixedly installed on the push plate and penetrates the installing plate. The energy storage spring sleeves the spring pull rod. The compression air cylinder is installed on the base, and a piston rod of the compression air cylinder is connected with the air cylinder pull rod. The locking mechanism I is arranged in the middle of the air cylinder pull rod. The invention further provides a spring energy storage type horizontal impact test method. The spring energy storage type horizontal impact test stand and method is simple in structure, good in adaptability and reliable in rest data.

Description

technical field [0001] The invention relates to the field of horizontal impact tests, in particular to a spring energy storage type horizontal impact test bench and a method. Background technique [0002] In engineering practice, impact problems are often encountered. Generally speaking, when an object with a certain speed (impact object) collides with a stationary object (impacted object), the movement of the impacted object will be blocked and stop in an instant, and the impacted object will be impacted at this time. . In this process, the impacting object gets a great reverse acceleration, which will exert a large inertial force on the impacted object. Shock is an unavoidable problem, which has a great impact on the use of mechanical equipment, transportation of products, and guarantee of performance and reliability of aerospace vehicles in many aspects, especially the impact on aerospace vehicles. [0003] At present, most of the impact tests of aerospace products and...
