[Abstract]:Abstract: the telescopic crane mobile crane is a widely used in various fields of national economic construction, and the torque limiter is a core part of crane safety monitoring system, directly affects the operating safety of the crane, with the requirement of safety and reliability of telescopic crane is more and more high, the precision of the torque limiter more and more is also high. This paper researches and Realization of telescopic crane torque limiter algorithm.
Reviews the current development and research status at home and abroad telescopic crane torque limiter, based on analyzing the working principle of telescopic crane torque limiter, completed the crane to establish heavy performance regression model, and the torque limiter for core moment algorithm are analyzed.
Stress analysis of telescopic crane arm frame combination, established the calculation model of crane luffing cylinder pressure based on torque, presents a new self calibration algorithm for the main arm, focuses on the research of deformation compensation algorithm of telescopic arm, and use matlab to simulate the algorithm, verify the feasibility of the algorithm.
The neural network is applied to the telescopic crane torque calculation was studied, compared with simple BP neural network, genetic algorithm and particle swarm optimization BP neural network training efficiency and prediction error. The results show that the BP neural network particle swarm optimization algorithm model of torque limiter has good fitting ability the prediction error through the trained neural network control in less than 3%.
The hardware platform of torque limiter based on DSP is built. Taking the CodeWarrior integrated development environment as software platform, the corresponding DSP program of the host controller is developed, and the development of the man-machine interface of the torque limiter displays is completed.
LabviEW has developed a data acquisition system based on the experimental research on SWTC50 telescopic crane as the experimental platform, the result shows that the precision detection algorithm of luffing cylinder pressure to meet the national standard GB12602-2009 crane overload protection device based on the requirements for the engineering application, the next step to lay the foundation.
