title: Efficient unloading system of turn back car dumper
abstract: An efficient unloading system of a turn back car dumper comprises the car dumper arranged on a heavy loaded car rail, wherein a heavy loaded open car to be loaded area is arranged in front of the car dumper; a traveling platform is arranged behind the car dumper; a car puller is arranged on another rail parallel to the heavy loaded car rail; an empty car rail is arranged near the rail on which the car puller is arranged; a car pusher is arranged near the empty car rail. The efficient unloading system has the characteristic that the length of the traveling platform is longer than twice of that of an open car which can be turned and unloaded by the car dumper in one time. As the traveling platform is lengthened, the efficient unloading system adopting the technical scheme becomes an unloading system with feed through layout in a period, and the working efficiency of the unloading system is improved. As the traveling platform is simple in structure, low in construction cost and high in reliability, the working efficiency of the unloading system can be improved greatly on the basis that the one time car turning and unloading amount of the car dumper is not increased greatly.

title: Research on Synchronization Control of Dual Motor Driving for Large Rotary Car Dumper
abstract: Car dumper is an important material transport equipment which has characteristics such as large structure, heavy duty, low frequency operation, stop and go and recurrent excursion of machine barycenter. This paper researched implementation of synchronization control. A fuzzy controller is added between two channels of dual drive subsystem. Based on coordinated control principle and achieving the goal of difference minimum of corresponding state of two subsystem, a fuzzy correction control program using in phase error non uniform common feedback is adopted to make the output of two synchronous subsystem consistent basically, which increase response speed of system to synchronous error, reduce synchronous error of dual drive subsystems effectively, ensure the consistency of car dumper dual drive, solve the recurrent mechanical failure caused by inconsistency of dual drive and enhance the steady reliable operation of car dumpers. The synchronization control strategy presented by this paper provides favorable guarantee for synchronization precision of multi subsystem in large rotary equipments and at the same time explores new ideas for other synchronization control systems.

title: F RBFNN Used for Tuning Parameters of Adaptive PID Control for the Drive Motor of Car Dumper
abstract: In the current environment of energy saving, dumper run energy efficiently that has great practical significance. The drive motor speed determines the roll over machine efficiency, with the result that motor speed optimal control using adaptive PID control system. Contrary to the volume of PID control, using neural network online tuning; On hand of network selection, RBFNN and F RBFNN are selected. Compared with the classical PID control, the PID control based on F RBFNN and RBFNN achieve the amount of online tuning the parameters of PID control. Especially, compared with RBFNN, F RBFNN which combines a fuzzy logic technology and RBFNN is more suitable for real time nonlinear control of the roll drive motor speed. Because parameters tuning more rapidly and static and dynamic performance and anti interference ability more powerfully.
