When the rotary speed is equal to 300 r/min,the dynamic load coefficient reaches 1.3.When the strength of the rod string is calculated,it is necessary to consider the influence of the dynamic load coefficient.
In this paper a approximate algorithm to dynamic factor and combined tooth form factor is proposed by means of BP neural network mapping,so as to decrease calculation scale of them and improve calculation efficiency of gear calculating stress.
Simplified formulas for calculating dynamic factor and operation factorunder typical operational conditions, which is appropriate for special characteristics of such cranes, is alsogiven for reference.
Meanwhile,the dynamic optimization model is given with the minimum of the gear dynamic load factor of the lower speed,The stiffness and damping of the suspension bearing are designed with dynamic optimization.
AbstractThe research indicated that the dynamic load action on face support comes form two aspects,i. e. sudden destability of the main roof and the impact of folling block from the immediate roof in gob, and the coefficient of dynamic load is about up to 10￣3.The normal acting on face support is from two aspects aswell,i.
This paper established and solved on microcomputers the single degree of freedom non linear model of mechanics and the kinetics equation for wide faced involute helical gears and worked out computer program for calculating the dynamic load of gears and coefficient of dynamic load.
