The Design And Analysis Of The Target Chamber Interior Maintenance Equipment

The targeting Interior Ministry maintenance equipment comes from the “SG-III”, which is the State’s major research project. The development of the subject is used for maintaining the inner wall of the target chamber in the host laser device projects. Routine maintenance requirements of large-scale demolition laser experimental device is very high. The equipment should contain all functionalities of ordinary aerial devices and adapt to the special shooting range complex e nvironment such as clean and narrow. Therefore, it’s necessary to get a dedicated maintenance equipment assist to complete job tasks. The equipment the paper developed not only has multiple degrees of freedom, large working range and small shrinkage volume, but also meets to high load. At the same time, the working principle of this equipment can be used to meet the job with similar special requirements.Firstly, according to the complex environment and practical needs for tasks, compared with similar lifting equipment technical parameters, the paper provided two general schemes. Then, established 3D model of the equipment on Pro/E, analyzed the equipment works, structure form and responsibilities in detail, and strictly compared pros and cons of program, developed overall program of the target chamber interior maintenance of equipment and the program of the various components. Secondly, designed the telescopic table, vertical telescopic boom and chassis systems in detail, including structure, size, driver arrangement and intensity analysis. Then, according to the practical conditions, checked stability of vertical telescopic boom, and anti-overturning stability of overall equipment. So far, the paper got the structure of working device of each module.The dynamic and static properties of Targeting Interior Ministry maintenance equipment are the key factors affecting equipment performance. Based on ANSYS, the paper finished targeting Interior Ministry maintained equipment’s finite element analysis. With modal analysis in extreme working conditions, the paper got the 6 extended natural frequency and main vibration mode, which provided the basis to effectively avoid resonance frequencies and for rigid-flexible coupling dynamic analysis.Then, completing static anal ysis in extreme working conditions after loads, the whole equipment and important parts of finite element static calculation result shows that the equipment of equivalent stress is less than the permissible stress of the material, meet the strength requirements and also meet machine most distal of the maximum deformation rigidity in the design specification requirements.Dynamic loading due to inertial effects can’t be ignored while large lifting equipment is working, so it’s important for dynamic analysis of multibody system. Based on D-H coordinates align times transform, the paper completed kinematics analysis for Target Chamber maintenance equipment, derived table end displacement explicit expression type, gained equipment’s reachable workspace.And it provided basis for dynamics analysis. Secondly, based on equivalent elements integrated method, the paper established dynamics equation of this whole equipment. Then, the paper finished dynamic simulation with flexible coupling for the equipment in ADAMS. Simulation result showed the corresponding stress curves of the hydraulic cylinder, provided the basis for the design of the hydraulic system. At the same time, Simulation result showed corresponding displacement, velocity and acceleration curves, checked the accessibility of equipment work space and stability. Finally, in order to reduce telescopic boom minimum quality, the paper optimized the telescopic structure, which benefit for operation lightly.
