Method of modeling the strength and stability during turning of the set «device-blank» using the program SOLIDWORKS Simulation
The relevance of the work lies in the fact that when machining the hulls of navigation instruments of aviation equipment, surface and underwater vehicles, special devices are required. In order to exclude preliminary testing of devices and fine-tuning, it is necessary to simulate the strength and deformation values of their structural elements. The article presents the results of research of the set «Special Mandrel-blank of the part «Housing» according to the specified parameters using the program SOLIDWORKS Simulation.
Keywords: mandrel for turning; screw clamping force; set stability modeling; set strength modeling; non-rigid bushing turning; screw connection simulation; set tension study.

Optimization of technological parameters of manufacturing details (castings) from thermoplasts with the use of the Moldflow Insight program
The aim of the work is to conduct research with the aim of improving the quality of manufacturing parts (castings) from thermoplastics in cold-channel molds. The study is conducted using the program "Moldflow Insight 2016". As a result of the study of the technological process of manufacturing the “Plata” part, the following shortcomings were revealed: underfilling, warping after casting extraction. After changing the mold cooling system, the reanalysis showed the elimination of the warping defect, and by increasing the injection pressure, underfilling is eliminated. In addition, the casting cycle is reduced by reducing the cooling time. The research results presented in this paper are useful to technical personnel involved in the design of foundry equipment.
Keywords: optimization of the cooling system; injection molding; temperature control of molds; conformal cooling.

Simulation of on-board electronic equipment frameworks using SOLIDWORKS Simulation software complex
A package of engineering analysis of SOLIDWORKS with the CAE Simulation module application software is used in the article for computer analysis of vibration strength of the part body of the on-board electronic equipment with electromagnetic relays installed. The analytic model based on the existing 3D model made it possible to find its self-resonant frequencies of the part, which confirmed the hypothesis of relay failures under vibration effects. On the basis of the experiment, it is proposed to increase the first natural frequency of the part body in three times, which reduce the vibration load of electromagnetic relays
Keywords: frameworks; electronic equipment body; self-resonant frequencies; simulation of vibration effects; electromagnetic relays.

Methodology of quality management in production preparation based on functional systematics methods.
Part 1. Modification structures of formula functional computer system of precision parts of gyroscopic devices
For the digital economy, in the context of growing production of high-tech products, controlling the accuracy of manufactured parts based on the laws of technological inheritance becomes of particular importance. The current task is to develop information support for quality management, which allows you to quickly carry out work to prevent defects in the machining of parts. The basis of such support can be the methods of functional systematics, allowing to create a single system of description of material objects for various branches of technology. The proposed approach allows improving both the process of diagnosing complex technical systems and preventing part failures.
Keywords: information flows; technological changes; quality indicators; structural shape; action classifier; functional assignment; «Gyroscopic Frame» part.
