Structural Optimization Design And Experimental Analysis Of The Dead Pigs Vehicle

It is a pivotal year in the transition for the transformation of the hog industry in 2017.With the gradually deepen of environmental investigations,small and medium-sized retail investor with high pollution and low efficiency will be retired,while aquaculture leader with the large-scale and standardized will rapidly expand,and large-scale farms will account for leading position.When these large-scale farms invest in environmental protection,they need to consider a series of problems in the processing of sick and dead pigs.In this paper,we study the equipment used to transport dead and sick pigs during the process of treating dead pigs,unlike small logistics robots,the quality of sick pigs which will need to be transported are generally larger.It is impossible to use crawler robots to put the dead pigs on vehicles.There will consume more time and laborious if people move the dead pigs on vehicles.In order to prevent death of pigs from infecting other healthy pigs and achieving healthy breeding,a higher automation degree of dead pigs vehicle is designed.The structural optimization design of the dead pig vehicle pigs was completed.By performing the mechanical performance analysis,statics verification,statics stability and dynamics stability analysis and dynamics simulation and later,by improving the prototype and testing analysis to verify the reliability of structural optimization design.The specific content are as follows:(1)First,analyze the existing transfer robots with different types,determine the structure type of the vehicle,optimize the overall and key components of the vehicle,and use SolidWorks software to build a three-dimensional model of a dead pig vehicle.It was carried out to calculate and select the driving motor of the dead pig vehicle,and calculated the maximum force applied to the traction rope.Using finite element analysis software of SolidWorks Simulation to complete the static check of the key components of the dead pig vehicle,and ensure that its structure has sufficient mechanical strength,and then to provide theoretical guidance for the structural stability of the vehicle.(2)By performing the static stability analysis and the motion stability analysis during straight-line running when added to the dying pig vehicle load and the center of gravity of the turntable and the gantry structure is moved back by 60 mm.And established a corresponding analysis model to optimize the structure of the haul vehicle.This provides modification for the structural optimization design.(3)Using SolidWorks which is a 3D Solid Modeling Software and Adams which is a mechanical system dynamics simulation software to build a simulation model of the rotating frame,and using ADAMS software to simulate the dynamics of the rotating frame when the forces are undered to the pulley and the front support bar in the ADAMS environment.And then add the necessary drive for the system,simulate the movement of the rotating gantry,and obtain a series of simulation data on the kinematics and dynamics of the rotating gantry.And then obtain the relationship between the rotation of the rotating gantry and the force of the component.This provides an optimized design solution for the production of physical prototypes.(4)An improved prototype of a dead pig vehicle was constructed based on the optimized structural design,and using this improved prototype for experimental analysis.Finally,the vehicle is suitable for large-scale farm transportation operations and can be easily and independently operated by one worker after the structurally optimized.And a series of actions can be quickly completed,such as dragging,hauling,and unloading.It can be realized to transport the dead pigs from the narrow pig house to the designated processing site of dead pigs.
