The Mechanical Simulation Of Buggy Ladle Based On Virtual Prototyping Technology

The buggy ladle is one of the most important equipment in carrying ladle and liquid steel and a necessary means of transport in refining outside the furnace, and the transportation of liquid steel is an indispensable important link in steelmaking process. From steel-making converter and secondary refining to the final continuous casting, the transportation of liquid steel on the ground relies on the buggy ladle to complete among various kinds of technological processes. There are some problems in structure design such as complexity, bulkiness and unreasonable and causing the concentration of stress and unreasonable stressing by the traditional experience design method. Complex bulky structure will result in excessive use of materials, the driving force demand increases, improper driving and operating conditions can also cause poor health and security risks.In order to improve the health of the whole ladle car, the ladle car increase the safety and reliability of the car's steel frame statics analysis, and the whole dynamics simulation analysis on this basis, the impact on the ladle car stable several factors of design verification, including the size of the track rail joint gap, drive ladle car, the ladle car's acceleration and deceleration time and speed steel chartered. The simulation results of the analysis carried out research on the one hand to provide amendments to this article ladle car, on the other hand provide a reference for subsequent ladle car designs.In view of the above-mentioned facts about buggy ladle, making the following research:(1) Establishing a finite element model according to the practical engineering blueprint, executing static analysis and obtaining the static characteristic of buggy ladle frame structure in the typical conditions. On the basis of statics analysis, putting forward the optimization scheme and verify its validity by static analysis.(2) Based on the modeling method of dynamic virtual prototype, we use the rigid body modeling. Establishing the three-dimensional entity model of buggy ladle frame, wheels, track and ladle and assemble them in Pro/E according to the optimized frame data. After that, importing it into ADAMS and building an integrated buggy ladle virtual prototype.(3) Simulating the tail joint clearance exist in full-load operation. Tail joint clearance is the mail research object. Finally, getting the impact load coefficient where the buggy ladle through the rail joint, and comparing with calculated value and specification requirements.(4) Making a whole process dynamics simulation for buggy ladle's full-load operation condition. The displacement-time process of complete machine and the acting force between various components factually reflect the dynamic characteristics. Varying different start acceleration, braking acceleration and running speed and confirming the influence of acceleration and speed on buggy ladle's vibration in the operation and judging that whether the optimum acceleration and the maximum speed are meet the requirements.
