Skew bevel gears are fundamental element of transmission system. Processing quality of skew bevel gears has impact on the performance of system. An accurate processing method of tooth surface of skew bevel gears with spherical involute is proposed. According to the space meshing theory, the meshing equation of skew bevel gears is built by the theory of coordinate transform. And the generating principle of generation line of tooth surface about skew bevel gears is studied. In terms of the formation theory of tooth surface, moving process model of milling processing is established. And the generation line is as chord of face circular cutters to cut the tooth surface. Machining of the profile of skew bevel gears is performed using three axes linkage by the method. Finally, the transmission experiment proves that this method can improve dynamics and strength characteristics. © (2013) Trans Tech Publications, Switzerland.

According to the model devised by the design team of PACE Future Bus and the layout size of pure electric coaches in the market, we used CATIA to make a 3D model and made Topology optimization design by using HyperWorks. After that, we imposed loading according to specific conditions and made structural topology optimization and sized optimization design. Then we checked the coach skeleton beam element model and the strength of shell element model. Finally, the future bus frame was built completely. © (2014) Trans Tech Publications, Switzerland.

The surface quality of components produced through milling of particle reinforced aluminum matrix composites (PRAMCs) is one of the most important factors influencing their practical performance. Therefore, the increasing applications of PRAMCs necessitate an in-depth understanding of the variation law of surface integrity. This paper presents a systematic experimental research of high speed milling of Al/SiC/65p (65% volume fraction) by polycrystalline diamond tools (PCD). The influences of cutting parameters on surface roughness (Ra), surface residual stress (RS) and morphology of PRAMCs were investigated. In addition, the experiments on corresponding unreinforced matrix alloy Al 6063 were also carried out to analyze the influence of the present reinforcements on surface integrity. The results of full factorial experiment revealed that the most significant milling parameter for surface roughness was milling speed, followed by the interaction between feed rate and milling speed, then the feed rate. In terms of residual stress on the machined surface, axial depth of cut had the highest influences on surface residual stress, followed by milling speed and feed rate. The results of single-factor experiment demonstrated that surface roughness improved slightly with the decrease in the feed rate, while the effect of milling speed was negligible. Residual stress measured in feed direction by X-ray diffraction (XRD) indicated that the conditions of machined Al6063 surface were all tensile, while the conditions of Al/SiC/65p were compressive.

Based on the deeply study on VERICUT, the generating process of spiral bevel gear surface is simulated in this paper. A certain surface generation process of spiral bevel gear is analyzed as an example. First the 3D solid models of gear cutting machine, cutter and gear blank are built. Then the NC program is compiled based on the generating principle of tooth surface. Finally the surface generating movement of spiral bevel gear is realized through selecting control system and importing the NC program. It can be indicated that the simulation analysis of surface generation can optimize the cutting movement and provide theoretical basis for the movement analysis of gear cutting. © (2013) Trans Tech Publications, Switzerland.

Based on the the principle of generating line of spiral bevel gears, a new modeling method about spiral bevel gears is proposed. Mathematical pattern of spiral bevel gears with spherical involute is developed about two parameters. A kind of simulation modeling software of spiral bevel gears with spherical involute is developed in matlab-guide environment. The data of tooth-surface are collected and calculated in the simulation system according to the machining parameters of a pair of gears which are established. It is convenient to establish accurate solid models of spiral bevel gear by obtained data points. Thus it can provide a feasible and effective way for CAD/CAE modeling and is modeled perfectly in computer so as to simulate the platform of virtual manufacture and meshing analysis. © (2013) Trans Tech Publications, Switzerland.

The reason of making propeller error in grinding square aspheric optical elements is analyzed. Each rigidity index of two fixing methods of abrasion wheel axis is calculated, and then the influence of abrasion wheel axis fixing position on the processing accuracy. The experiment at each position is done. Different abrasion wheels and different processing parameters are used to do the grinding experiment. Finally, the abrasion wheels axis fixing position and the grinding processing parameters which can satisfy the processing accuracy of square aspheric optical element are obtained.
