Abstract

The invention relates to a high speed hasten device, which is a hasten device to accelerate the object to the high speed status in the high speed impact experimentation. It uses the electric energy of the common use electromotor to replace rocket or high pressure gas in the traditional method; in the meantime bobbin with special design keeping the object invariable acceleration in the accelerate process, consequently, keeping cord and bracket equipment endure the equal stress, eliminating the impact function; the harmony work of the whole device can guarantee the equal accelerate experimental effect with the traditional method. Compared with the existing technology, its advantages are that it is simple in structure and easy to implement, low cost, safety and reliability, while the low price of experiment, can save a lot of energy consumption, and can be more controllable and stable acceleration, reduces the restrictions of the corresponding performance requirements, making more extensive equipment selection. In short, this device has high controllable, fully meet the requirements of impact test, and save a lot of manpower, material and financial resources.

Description

technical field [0001] The invention relates to an acceleration device for accelerating an object to a high-speed state in a high-speed impact test, and belongs to the field of aeronautical engineering and related technologies. Background technique [0002] In many application fields, it is necessary to study the motion and impact characteristics of objects under high-speed motion. For example, in the aviation industry, the study of high-speed impact is of great significance. It is not uncommon for aircraft and birds to collide in the air and cause aircraft damage or crashes. According to the analysis of statistical data, the impact speed of birds is generally about 150m / s, and the duration is only a few milliseconds. Therefore, the study of high-speed impact is of great significance to the performance of aircraft windshields and the strength analysis and design of engine blades. In recent years, the role of the flight recorder (FDR, commonly known as "black box") has beco...
