Embodiment Construction

[0042] In order to simulate the real environment, my country urgently needs to develop a strong impact testing machine with large load, low cost, high acceleration and negative waves in the laboratory environment to meet the impact test requirements of civil and military equipment.

[0043] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The present invention proposes a new way of negative wave generation, that is, the test bench and the shock bench are connected together by an interlock mechanism and braked at the same time, and the connection method can also be replaced by other feasible mechanism connection methods. It can be understood that the described embodiments are part of the emb...

Abstract

The invention relates to a vertical high-speed impact testing machine capable of generating negative waves; guide pillars are oppositely arranged on a base of the testing machine, an impact table and a test bed are in clearance connection with the guide pillars, and interlocking structures are arranged on the impact table and the test bed; a lifting hydraulic cylinder is further arranged on the base, the upper end of the lifting hydraulic cylinder is connected with a release device, and the release device can be inserted into or separated from the test bed; a brake device is further arranged on the base, and the upper end of the brake device is connected with the impact table. According to the invention, a higher acceleration response peak value can be obtained, and the impact effect far exceeds that of a traditional impact testing machine; clearer impact negative waves with different pulse widths can be obtained; the generated impact vibration cannot be transmitted to a ground building; no hydraulic oil path is arranged on the test bench and the impact bench, and reliability and durability of the testing machine hydraulic system are improved.

Description

technical field [0001] The invention relates to the technical field of impact testing machines, in particular to a vertical high-speed impact testing machine capable of generating negative waves. Background technique [0002] With the rapid development of the aviation and marine parts industry, the quality requirements for parts and components are getting higher and higher. While meeting the design specifications, their mechanical properties must also meet various technical requirements. In order to verify the final performance of each component, it is necessary to use test equipment to carry out test and detection to ensure the safety of each component. As a test equipment for testing and assessing the impact resistance of various metal and non-metal materials, the impact testing machine is widely used in the performance testing of key components (steering knuckles, drive shafts, etc.) in the fields of aircraft and ships. [0003] In the impact test, in addition to the str...
