| Abstract: |
| Kiln are the key equipment in the production of metallurgy, cement and material of fire-fast. It is the statically indeterminate system with over load, large torque and multi-support. Because of the complexity of load and stiffness distribution of the rotary kiln, the deflection of supporting center, the supporting load distribution will become seriously non-uniform. To the characters of load and stiffness distribution of the rotary kiln, the mechanical model and equation group are established, which are used to solve the variable-stiffness beam upon complex load for kiln. The relation between the supporting load distribution and deflection is derived. Accordingly, the liner formulas for calculating the support force of the support wheels fixing on the rotate kiln are obtained from the practical calculation of rotary kilns, and some useful analysis conclusions are obtained. This will provide helpful guide to condition analysis and optimization control of rotary kiln. |
