| Double-track underslung conveyor is a new crane and tansport machine, the use of double track layout and 4 point hanging with a running smoothly and high carrying capacity, will have good market efficiency and practical value. This double-track underslung conveyor is not designed in our country. With the development of automobile and machinery manufacturing, particularly in the workshop production line, performance needs better transportation equipment. Therefore, the design for the new double-track underslung conveyor has great significance.Double-track underslung conveyor requires steady and reliable dynamic performance. We could only design and manufacture single-track underslung conveyor at present. The theory results are validated only through a lot of physical tests, which leads to increase investigative cost and defer the course of industrialization. The modeling and simulation of dynamics provide a quick and reliable technique for the design and amelioration of the double-track underslung conveyor system. The manufacturing cost of the equipment has greatly decreased.Use bus body as the design and analysis of cargo, has 12000×2500×3300 (mm) dimensions. Double-track conveyor main parameters of the selection decision directly to the stability of the system performance, We should first determine the conveyor performance larger technical parameters of the design value. According to transportation equipment truck, beats and production space, the requirements of the work, combining traditional design experience, Operation of the design agencies, including wheel-track pressure, running resistance, traction motor power and conveyor minimum bend radius of orbit. Established the main technical parameters of double-track underslung conveyor.Based on the conveyor simplified, Based on a conveyor framework of the Conveyor System Dynamics mathematical model. In the virtual prototype simulation environment for the conduct of tests, the main consideration through the conveyor track radius bend wheel drive, running round and suspension center and other key contacts and walking device stability. Driving wheel and track these contacts to the law and running round the smooth torque curve, Suspension center of speed and acceleration is smooth passage system can bend radius of the main track yardstick.Flexible body deformation of the system has a great impact, drives the entire conveyor one of the key installations. In finite element analysis software ANSYS establish flexible body with a rolling model neutral file, Introduction ADAMS and simulation analysis. Consider the deformation driving wheel to be more accurate in the conveyor track of the dynamic properties. |
