Шляхи адаптації та модернізації випробувального обладнання для відтворення ударних навантажень виходячи з вимог стандарту MIL-STD-810

Abstract

The subject matter of the article is the process of testing the objects of general use, aviation and space industry, railway transport, electric power industry, and nuclear industry on the impact of shock loads. The goal is to implement modern international standards, in particular MIL-STD-810, in the practice of testing laboratories. The tasks to be solved are: to study the possibility of using vibration stands in impact testing and to modernize the existing test equipment by developing a new software for control systems based on existing and proven algorithms. To achieve this goal, the analysis of current regulatory documents was carried out and the existing experience in the conformity assessment was adapted. The following results were obtained: a research test stand was created using the technical capabilities of the Test & Certification Center of RPI “HARTRON-ARKOS” LTD. The software was developed using standard library elements from the SCADA system. The capacity of using a vibrating stand during impact testing was taken into account, and an iterative impact control mode was implemented. The operability of the modernized test equipment was confirmed by full-scale verification of all parameters with a positive result, and approbation was passed during real tests in various modes for complex test objects. This paper formulates proposals for expanding the capabilities of the existing laboratory and testing base when implementing MIL-STD-810. The proposed approach to software development allows the replication of the code in any other software environment. A comparative assessment of financial and time costs for the purchase of new and modernization of existing equipment confirms the economic feasibility of the described approach. The perceptiveness of the adoption of the MIL-STD-810 standard as a state standard of Ukraine was defined. It is proposed to use this standard in the practice of testing laboratories to conform the requirements of developers and manufacturers in various industries, as well as a basis for industry standards, which ensures the replacement of outdated and canceled standards.
