Optimal Design Method

According to the structure features of gear system in co-rotating twin screw extruder, the model of the gear system is built, and multi-objective optimization genetic approach based on the Pareto-rank is proposed to optimize the parameters of the gear system. The advanced optimal design method for the gear unit in co-rotating twin screw extruder is studied. A typical gear system in co-rotating twin screw extruder is designed, and the results show that the gear system meets the requirements in all aspects. This design method of the gear system is synthetic optimization for the gear system in co-rotating twin screw extruder.

Optimal Design Method

For the difficulty of calculating the size of the Pre-Manufactured hole of flanging, the formula was derived by using the theory of equal line length and the theory of equal area. And the formula was verified by finite element simulation. Due to theoretical formula has certain error, the optimal design method based on interpolation was put forward and optimization design the size of the Pre-Manufactured hole of flanging. Engineering example shows that this optimization design method is accuracy and convergence speed, and it can quickly calculate the the size of the Pre-Manufactured hole of flanging.

Vibration screener is an important mechanism which is widely applied to metallurgy, building materials, chemical industry, grain, mine, etc. On the basis of deeply studying work principle and support structure of vibration screener, the paper conducts ZKB Linear vibration screener as study object. According to mass of vibration, vertical stiffness, horizontal stiffness, vertical amplitude, horizontal amplitude, and free high of vibration screener support spring, the paper conducts the lightest weight of support spring and the biggest fatigue safety factor as the objective function of multi-objective optimization design to establish a series of constraints. Then using of the penalty function method of optimization theory , the paper gets the optimal design results of support spring and gives the optimal design dimensions, which provides a reliable design method of support spring for the future design of vibration screener and reduce the blindness of the design .
