Fuzzy Finite Element Optimization of High-speed Vertical Machining Center Spindle Box Jujiang Cao 1, a, Leihua Wang 2, b, and Jun Lu3, c 1 College of Mechanical and Electrical Engineering, Shaanxi University of Science and Technology, Xi’an 710021, china 2 College of Mechanical and Electrical Engineering, Shaanxi University of Science and Technology, Xi’an 710021, china 3 College of Mechanical and Electrical Engineering, Shaanxi University of Science and Technology, Xi’an 710021, china a jjcao@sust.edu.cn, b wanglh323344@126.com, c lujun1436@163.com Keywords: Fuzzy optimization, Membership functions, Spindle box Abstract: The key component of the spindle box for using the fuzzy optimization method for high-speed vertical machining center was optimized.
The parameters determine: the material is carbon steel cabinet, Young's modulus, Poisson's ratio, carbon steel ultimate stress for the 300MPa, take the safety factor n = 1.5, allowable stress.
As part itself consists of a material form, so its quality optimization can be transformed into the optimization of the volume, so the objective function will set the volume of parts.

The analysis and design of smart structures involves a highly multi-disciplinary effort which includes structures, materials, dynamics, control and design.
The characteristics of smart structures can be described as intermediate between those of smart materials and smart systems.
Aerospace technology was the original motivation that spurred the growth of composite materials where high strength and stiffness at low weight is of prime importance.

Besides being of interest from the point of view of fundamental science, borophosphates have also attracted attention for a variety of technological applications in catalysis and ceramic engineering [4, 5], as well as for fast ion-conducting materials [6-8].
Furthermore, alkaline-earth borophosphates are interesting solid-state materials which have an isoelectronic relationship with silicates.
These materials are biocompatible with the living body, so they are called bioceramics.
The infrared studies of these materials have not been reported before.
Besides that, it also provides good information at exploring new functional materials, especially for the nonlinear optical materials.
