Preform Optimization of Functional Bevel Gear for Warm Forging Processes

This study applies the finite element method (FEM) to predict maximum forging load and effective strain in bevel gear forging. Maximum forging load and effective strain are determined for different process parameters, such as modules, number of teeth, and die temperature of the bevel gear forging, using the FEM. Finally, the prediction of the power requirement for the bevel gear warm forging is determined.

This study applies the finite element method (FEM) to predict maximum forging load, billet volume and effective strain in near net-shaped helical-bevel gear forging. Finite element analysis is also applied when designing the near net-shape of a helical-bevel gear, a reverse forming approach to acquire the initial dimensions of the billet based on the forward forging of the helical-bevel gear. Maximum forging load, billet volume and effective strain are determined for different process parameters, such as modules, number of teeth, helix angle and workpiece temperature of the helical bevel gear forging, using the FEM. Finally, the prediction of the power requirement and billet dimensions for the helical-bevel gear warm forging are determined.

Stress Damage

According to the shape character of half axle bevel gear forging a process based on closed-die forging scheme was proposed. Based on a series of simulation the influence of initial forging temperature on forming force, the influence of web thickness and web position on stress, damage factor and forming force were analyzed. According to numerical analysis the web dimensions and forging temperature which ensure a minimum stress, a minimum damage factor and a proper forming load were achieved. The forming result was simulated and evaluated, and the forming load was controlled under 760ton. At last the research project got good test verifying.

Damping Model

The vector form intrinsic finite element (VFIFE) method is springing up as a new numerical method in strong non-linear structural analysis for its good convergence, but has been constricted in static or transient analysis. To overwhelm its disadvantages, a new damping model was proposed: the value of damping force is proportional to relative velocity instead of absolute velocity, which could avoid inaccuracy in high-speed dynamic analysis. The accuracy and efficiency of the proposed method proved under low speed; dynamic characteristics and vibration rules have been verified under high speed. Simulation results showed that the modified VFIFE method could obtain numerical solutions with good efficiency and accuracy. Based on this modified method, high-speed vibration rules of spiral bevel gear pair under different loads have been concluded. The proposed method also provides a new way to solve high-speed rotor system dynamic problems.
