Generalized mathematical model of fastening technology of cargo with pads jointly with flexible and thrust elements under the action of spatial force system

The article gives an account of the results of the constructed generalized mathematical model of fixation of cargo with pads jointly with flexible and thrust fas-tening elements. Developed for the first time the generalized mathematical model of collat-eral fixation of cargo with padding by flexible and thrust elements made it possible to iden-tify the conditions providing workability of thrust bars together with pre twisted fastening wires and cargo pads. It should be emphases that it is only when these conditions are not fulfilled that elastic forces of flexible fastening elements are engaged in work on retaining cargo from shifting. The distinguishing characteristics of generalized model under the action of spatial force system as compared to specific models is manifested in its ability to provide workability of flexible fastening elements together with thrust bars and cargo pads according to the criterion of normative value of longitudinal (or lateral) load on a fastening component and allowable pressing tension of the most loaded of the used pads. The investigation results concerning cargo transported by and unprovided for in Specification [3] are now available for researchers and can be looked upon as a new stage in the development of this problem.
