Study On Simulation Platform Of The Jib Falling Accident Of Portal Crane

Crane and Conveyor is considered to be one of the equipment which cause accident easily. So the National security management department made series of standard to regularize workers' behavior and the condition of the equipment, created some managing and inspecting institutions, implemented lots of permit systems to guaranteed the quality of facilities and the security of people. However, the accident of Portal Crane still kept happening. In order to avoid this situation, control and eliminate hazards timely, furthest reduce casualties and property damage, reappearing the reality of the process of accidents is also can be one method of malfunction analysis and appraisal.Portal Crane is one of the common equipment of the port wharf. The Jib System is the main beaning parts of Portal Crane, its' performance decided the efficiency and security of the Portal Crane. Jib Falling is a typical accident of Portal Crane. It is significant to make some research on reappearing the truth.This paper takes the Portal Crane MQ4599as its study object.Based on the predecessor's research, Simulation Platform of this kind crane are deeply researched. Take advantage of software SolidWorks and3Dmax, imitating the process of Jib Falling. The main work includes the following aspects:(1) Qualitative analysis the parameters which influence the result of the jib falling accident. Design a man-machine interaction simulation platform with the use of VC++6.0, reappear the process of all kinds of accident.(2) The mechanisms structure models of selected Portal Crane are built and assembled on SolidWorks2010. The problem of interface between SolidWorks and3Dmax also need to be solved.(3) Virtual work scene of Portal Crane in the port wharf is established in3Dmax2010. Import the SolidWorks Model into3Dmax2010and add wire rope model. Make each mechanism model into group, append proper link relationship between them.(4) By analyzing the motion law in the ideal state of every stage of jib falling accident process, getting the key frames in cartoon, helping to simulate the process of jib falling and impacting the earth or not.
