The solution of the inverse problem of kinematics is described and the necessity of solving the direct problem of kinematics by numerical methods is substantiated. During the research, it was revealed that the main source of positioning errors of the hexapod without the main feedback is its linear drives, which have systematic errors in the mechanical part of the linear transmission, gearbox, in the location of the motor windings; temperature errors due to changes in the dimensions of parts due to heating or cooling; errors caused by elastic deformations under load. To improve the static accuracy of the hexapod, a number of both design and software solutions are proposed: mechanical transmission preload, individual calibration of each drive, compensation for thermal expansion, etc. To improve the dynamic accuracy, it is proposed to use the method of controlling linear drives in the servo mode along with ensuring the trajectory of the platform with the limitation of the speed of its movement and derivatives of the speed. The use of these methods makes it possible to significantly improve the accuracy of the operation of the mechanisms of a parallel structure and, thereby, to approach the achievement of the limiting qualitative properties of onboard optical-electronic and information systems of spacecraft and stations.","PeriodicalId":119001,"journal":{"name":"Spacecrafts & Technologies","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134297779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Priority areas of application of methods of vibration treatment of critical welded structures are highlighted: post-welding and related. The advantages and difficulties in the implementation of these methods are shown: the ability to control the efficiency of postwelding processing by changing the amplitude-frequency characteristics, increasing strength and plasticity and optimizing the geometric parameters of the weld, combining the processing time together with the welding production cycle with accompanying processing. Brief results of experimental work on the criteria of residual stresses and residual deformations for different types of welded joints, such as butt, T-bar and lap joints, and several groups of materials, such as aluminum alloys, carbon steels and stainless steels, are presented. The conclusion is made about the prospects of using post-welding vibration treatment for dimensional rigid, forming a closed contour, composed of their many parts and subassemblies of welded structures in assembly-welding special conductors or universal assembly devices, as well as about the initial reduction of residual deformations during concomitant vibration treatment of welded joints.","PeriodicalId":119001,"journal":{"name":"Spacecrafts & Technologies","volume":"438 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129073510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the side effects of the electric pump unit of the thermal control system, the urgent task is to reduce vibration activity when developing a new model for advanced spacecraft. An integrated approach to solving the problem is indicated with the consideration of electric pump unit as a system and the selection of several directions to achieve the root-mean square value of vibration acceleration of 0,01g and below. Possible methods for reducing vibration activity in each of the directions and implemented solutions in the developed sample are described in detail. On several versions of electric pump unit for experimental determination of the level of root-mean square value vibration acceleration at a frequency of 5–1000 Hz.

The main feature of the implementation was the mathematical and computational optimization of calculations, which made it possible to carry them out on a conventional computer without involving additional computational power. In the course of the work, corrections to the Everhart method were proposed to improve the trajectory integration step. Parallel implementation also helped to significantly speed up the calculations.

Some results of these works are presented, in particular, the preliminary design of a small space tug with an innovative two-component gas rocket engine powered by oxygen and hydrogen, operated in conjunction with an ultralight class launch vehicle. Small space tug solves the problems of interorbital transportation of the small spacecrafts. It has no analogues in the russian rocket and space technology. Variants of ballistically coupled groups of small spacecrafts are presented that can ensure the formation of a stable quasi-stationary distributed aperture in orbits in order to increase the efficiency of space communication systems and remote sensing of the Earth. The development of an innovative actuator – a two-axis rotary platform based on piezoelectric drives is presented. This device significantly exceeds traditional electromechanical devices based on electric drives in terms of weight, dimensions, dynamic characteristics and other parameters. The variants of the application of this rotary platform as part of the service and target systems of the small spacecrafts are considered. It is shown how this can provide a significant increase in the tactical and technical characteristics of the small spacecrafts.","PeriodicalId":119001,"journal":{"name":"Spacecrafts & Technologies","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131839199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors present the main problems of SpaceFibre, as well as ways to solve them. The first problem is related to the use of multi-channel data transmission in prospective Russian projects, as well as the need to increase throughput using existing equipment and physical cables. It is necessary to develop new transmission methods and algorithms and create a completely Russian version of the multilane level for the described standard. The second problem relates to the organization of data transmission in SpaceFibre networks with a large number of nodes and a complex scheme of data transfer flows, it is a consequence of an insufficiently developed network level of the standard. The authors give possible ways to solve the identified inconsistences of the standard using the concept of software-reconfigurable networks.
