In this study AZ31 sheet with a thickness of 1.2mm and diameter of 52mm was simulated to press into a dish by a finite element method(FEM) software, which to obtain better processing of plastics forming of magnesium alloy by varying die parameters. In order to find the way of development on drawing property and to formulate the rational stamping processing, simulations have been applied on the maximum principal stress various with round radius of dent die and round radius of punch and die gap. Simulation results show that: to obtain a dish of 29mm diameter, a sheet of AZ31 magnesium with a thickness of 1.2mm and diameter of 52mm has been drawn, the fracture occurring at the corner of dish wall bottom. the ability of drawing varies with the round radius of dent die, which better radius is 3.8 mm. In the same way better round radius of punch is 3.0 mm, while better half gap is 1.8mm. Experiments also show that high diameter ratio has been increased with the various of die parameters and forming ability of material has been developed. It is reliable of simulation of finite element method.

Element Method

The node position of amplitude transformer was determined by the finite element method, and the flange was designed at the nod position for conveniently installation. By the finite element software, the amplitude transformer with flange was optimized and dressed, and its structural parameters were determined. During the actual manufacturing process, it was used impedance analyzer to test its vibration performance, the testing results show that this system vibration performance is good, its resonant frequency is 34.771kHz, anti-resonant frequency is 35.008kHz. The above-mentioned results are very much coincided with the system natural frequency of 34.893kHz which is drew by finite element method. Compared to the traditional dressing this method has many advantages such as convenience, green, environmental protection, low cost and others.

The temperature fields during semi-solid magnesium alloy produced by casting-rolling technology has been simulated by finite element method on the basis of ANSYS. The temperature fields for different conditions were obtained, which is consistent with the experimental results. Results show that there is a high temperature field in the casting and rolling zone. The temperature fluctuates from the center to edge of the strip near the entry of the casting and rolling zone. but The temperature decreases gradually from the center to edge of the strip near the exit of the casting and rolling zone. There are some remarkable effects of the temperature of the casting and rolling, the velocity of the casting and rolling, the gap of two roll, the cooling of the roll and the diameter of the roll on the temperature field, which are in agreement with the experimental results.

In order to understand the vibration characteristics of the steering system and provide suggestions for improvement, a model of the steering system was created based on finite element method (FEM). Also, the modal analysis of the steering system was presented, and the first twenty step modes were calculated and analyzed. The steering system was also evaluated from the resonance point of view. The result shows that the frequency of the first step mode is 31.578 Hz which is higher than the exciting frequency of the engine; also, the road roughness excitation frequency has a minor influence on steering wheel vibration.
