Test Rig for Impulse Loading Based on a Hydraulic Impulse Drive

Problem Statement and Purpose. The lack of a methodology for studying the effect of impulse loads on ma- terials is a problem in mechanical engineering, which complicates the creation of structures with minimal safety mar- gins. The purpose of this work is to develop a drive design for an experimental test rig with an adaptive control system to study the effect of such loads on structural materials. Methodology. The methodology involves a theoretical analysis of existing test rigs and the development of a new design scheme based on a hydraulic impulse drive. A setup with a hydraulic accumulator for generating impulses is proposed, and a vibrator design with a built-in pressure impulse gen- erator and an adaptive control system has been developed. Results. Technical requirements for impulse testing instal- lations have been formulated. A schematic diagram of the drive has been developed, which can be installed on existing machines, and a design for a hydraulic impulse vibrator with an adaptive system to maintain constant load parameters has been proposed. Scientific Novelty and Practical Significance. The scientific novelty lies in the application of a hydraulic impulse drive with an adaptive system for material testing, which has not been described in the literature. The practical significance is the possibility of upgrading existing testing machines to obtain data on the behavior of materials under impulse loads, which will allow for more precise design of structures. Directions for Further Research. Further research should involve creating a prototype of the setup and conducting experiments to determine the mechanical properties of materials under impulse loads to verify the theoretical developments.
