As a new type of high-precision gear transmission mechanism, the transmission accuracy of the 2K-V reducer will be greatly affected by vibration. With the RV110E reducer as the research object, a three-dimensional model of the needle wheel is established. Using the finite element analysis software, the natural frequency and mode shape of the needle wheel are calculated, when it’s under the output condition, then compared with the calculated gear meshing frequency. It is found when the needle wheel is used as an output, the vibration frequency is within the gear meshing frequency range, which is easy to cause resonance, thereby affects the transmission precision of the whole machine. The part of the outer shell of the needle wheel and the oil seal of the skeleton is the weakest and prone to deformation. By adding 6 reinforcing ribs between the needle wheel flange and the outer casing, increasing the flange outer diameter at the same time, the natural frequency can be increased, the deformation concentrated region can be transferred to the outer casing and the reinforcing rib. The connected parts avoid resonance and increase the service life of the needle wheel.

This paper indicates a kind of research on the optimization of clamping scheme for the joint thin-walled parts in milling process .The three-dimensional model of four-flute end mill and the part are made by UG. The effect of different clamping scheme on the deformation of joint structure is simulated by the finite element analysis software ABAQUS. With the purpose of getting the minimum of the average deformation, MATLAB genetic algorithm optimizes the clamping scheme and acquires the best clamping scheme. The simulation and optimization provide an effective method for controlling the deformation due to different clamping scheme of aeronautic joint-shaped workpiece.

The basic structure of the piston hydraulic cylinder was introduced. A three-dimensional model was carried out for the hydraulic cylinder by using Pro/E soft,the finite element analysis to the largest hydraulic condition while hydraulic cylinder working by using ANSYS soft,and the distribution of the stress and strain of hydraulic cylinder was derived from it. It optimized the structure of hydraulic cylinder effectively and the cost was saved.

Using the mechanical design of the software Solid works to established the 280 t LF the ladle furnace transportation car frame three dimensional model, and by using the finite element analysis of software Cosmos/works to static analysis for the frames, revealing that the frame of structure stress and strain distribution map of the frame, and also reveals that dangerous points and dangerous sections. Using resistance strain gauge to measure 280 t ladle transportation car frame, it is concluded that the frame of stress and strain distributions. Through the electrical measurement test the results were compared with finite element analysis results, further proof that the finite element analysis of the accuracy of the results provides theory basis for the optimization design of the frames.

Hood is an important part of the automobile, which directly affects the vehicle performance. This paper takes the hood as an example, first of all the three-dimensional model in CATIA was imported into Hypermesh, then it was simplified and meshed, the constrained mode and the stiffness of several conditions were calculated by Optistruct. By using the Size Optimization based on sensitivity analysis, the minimum hood mass is defined as the objective function; each component’s thickness was optimized under the prerequisite of ensuing stiffness and the first modal of hood. The results show that: the optimized hood meets stiffness requirements, the whole vehicle performance can be improved, therefore, the lightweight design in this paper is effective.

The heavy triangular rubber track conversion for the construction machinery has existed the disadvantage for weight oversized. The effective reduced triangular rubber track conversion's weight is essential in the engineering design. This article established one kind of triangular rubber track conversion driving gear wheel axle's three-dimensional model, integrated dynamics analysis has carried on the finite element analysis to it, based on this and carried on the size using Ansys Workbench to optimize for its most superior structure size, finally to optimized the result to carry on the finite element analysis once more. The result contrast indicated that at maintains under the wheel axle stress level basic invariable premise, after the optimized wheel axle weight reduces greatly, enhanced track wheel's performance effectively.

A new type of U-shaped steel-concrete composite floor is analyzed in detail. The experimental test and finite element analysis of the floor are conducted to study the natural frequency and serviceability characteristics of the new composite floor structure. The natural frequency of the floor is measured under the environmental random vibration stimulating method, and the peak acceleration of the floor is measured under pedestrian-induced load. The experimental test results show that the U-shaped steel-concrete composite floor has better antiseismic behaviors and meet the specified serviceability requirements. The finite element analysis results indicate the constraints have a great impact on the calculation results. The experimental tests and FEM results of the floor are compared based on the modal assurance criterion, and the results are in good agreement. The experimental test acceleration curves demonstrate that the peak values meet the requirements of Chinese specification.
