Modeling of performance in estimation of design parameters transport-technological machines

Purpose. Reduction of costs and increase of productivity of use of transport-technological machines. Methods. Analytical. Results. The above dependencies for the calculation of productivity can be used at different stages of development and design of transport technology machines (TTM) make it possible to reduce costs. Conclusions. The above dependencies for the calculation of performance can be used at various stages of the development and design of TTM. In particular, it is advisable to use dependencies to evaluate the implementation of the design parameters of the TTM, since cycle performance is most sensitive to the parameters. In addition, the value Wц is the maximum achievable performance for some fixed values of the design parameters (ВР, Vк), characteristics (Vp, Qs, Rn) and conditions ( г, Q3, l4.1). It is advisable to use operational productivity for comparison of different variants of execution of TTM, since its value is influenced not only by design parameters and characteristics, but also by technological and technical reliability, operational manufacturability, organizational and technical factors.
