The diploma program is dedicated to the design and development of digital inclinometers. This device is used to adjust the inclination of construction structures, bridges, buildings, objects, etc. Digital inclinometers are versatile tools for a variety of tasks, from geotechnical surveys to building model airplanes. These devices measure tilt or tilt angles relative to a reference point and can be used to measure vertical or horizontal angles using sensors that respond to changes in light or darkness. The latest digital inclinometers use MEMS technology, which stands for micro-electromechanical sensors, while accelerometers use tilt sensors.
Thesis for a master’s degree contains an introduction, three main parts and conclusions. It also has 97 pages, including 40 pictures and list of references. The purpose of the qualification work is to develop a measuring system manipulator. To achieve this goal, the following tasks were performed: the main types of CMM (cantilever, portal, bridge and portable) are considered and compared; the method of operation of different scanning types and measurement of linear inductosines were analyzed; the principles of portable CMM of the "hand" type functioning was considered and the peculiarities of their structure were determined. The shoulders of the structure were designed. A calculation scheme was created to determine the load on them.
Actuality of theme. The modern level of development of instrument engineering, mechanical engineering and other fields of science and technology require high accuracy of angular measurements. Traditional means of angle measurement do not always meet the needs. One of the main reasons for this situation is the insufficiently high accuracy of angle measurements and angle converters that set the angle scale in measuring instruments. Therefore, today the question arises of improving the accuracy of measurements with a minimal increase in costs. The object of research is an interference null indicator. The subject of the study is the process of measuring the scale coefficient of the gyroscope. The purpose of the work: the study of the relative error of measuring the scale coefficient of the gyroscope with the specified accuracy of the zero indicator measurement. Also, this work assumes that after completing the theoretical studies, an experiment will be conducted, based on the results of which appropriate conclusions can be drawn regarding the use of the null indicator for measurements. A feature of the use of this interference zero indicator for the scale factor measurement stand is the use of a photoelectric multiplier in it, which significantly increases the accuracy of the measurement. Research methods: The work uses methods and criteria for evaluating different constructions of the interference null indicator for the scale factor measurement stand. The scientific novelty of the work is as follows: The use of a photoelectron multiplier in an interference null indicator for a scale factor measurement stand. The practical value of the results obtained in the work is that the proposed option significantly increases the accuracy of the measurement. Structure and scope of work. The master's thesis consists of an introduction, four chapters and conclusions. In the introduction, a general description of the work is presented, an assessment of the current state of the problem is made, and the relevance of the research direction is substantiated. In the first chapter, the only domestic enterprise working in this direction was described, as well as the structure, types and principle of operation of the laser gyroscope were considered. In the second section, the quality of the product was evaluated and the structure and principle of operation of the null indicator were described. The structure and principle of operation of the BDIV were also described. In the third section, the general requirements for the zero indication of angular measurement were formed, and an autocollimation zero indicator was developed. In the fourth chapter, the startup project was developed and the opportunities and strategies for its implementation were analyzed.
