| Summary: | Background. The object of the study is the conditions of assembly of long parts
connected with tension, widely used in various industries. The subject of the research is
assembly technology, restrictions imposed on the assembly process in its various types. The
purpose of the work is to develop well-founded recommendations for the selection of connection
parameters and assembly technology, eliminating the loss of stability, with the possible
use of more advanced technological processes and connections. Materials and methods.
An assessment is proposed that allows predicting the loss of stability during assembly
of long parts of tension joints. The study of assembly processes is carried out taking into
account the critical force according to the known Euler relation, taking into account the
method of installation and fastening of parts during pressing. The equations of the elastic
line of sections are determined using differential equations for individual sections of the
shaft and hole. The curved axis of the conditional rod is described by a system of differential
equations. Results. An assessment is proposed that allows predicting the loss of stability
during assembly of long parts of connections with tension, and recommendations for eliminating
the loss of stability of connection parts. An example of using the proposed assessment
is given. Conclusions. The proposed assessment allows selecting the parameters of the
connection and the technology of its assembly, eliminating the loss of stability. Technical
solutions are proposed that allow implementing more advanced technological processes of
assembly of connections. |
