Today, because of the rapid depletion of energy resources, scarcity of economic and material resources, strong technological competition and increasing environmental awareness, engineers are under immense pressure to produce optimal designs in order to survive.
On the other hand, the advent of new technology and materials, as well as the imminent introduction of many mandatory international regulations on engineering products, are making it increasingly difficult to obtain the optimal design of a device or system using traditional approaches.

Dynamic Analysis of a Truck Frame with Fuzzy Uncertain Parameters Zhikun Luo1, a, Ping He2,b, Wei Tan3,c and Guodong Jin4,d 1Center for Computer-Aided Design, Huazhong University of Science & Technology, Wuhan, China aemail:luyieer@126.com Keywords: Fuzzy Set; Uncertain Parameters; Truck Frame Abstract.
Hanss [8] used fuzzy parameters to express the Young’s moduli of the material on stress analysis using finite element method.
First we establish a finite element model of the frame, and elastic modulus and Poisson’s ratio of the material is considered as fuzzy parameters with triangular membership function.

The key techniques in the research of DPF are the filter material and filter regeneration [3-5].
The key techniques in the research of DPF are the filter material and filter regeneration, In recent years, research shows that cerium-manganese-based catalyst have excellent performance in oxygen storage and have highly catalytic activity, also can reduce ignition temperature of filter regeneration of diesel particulate filter effectively[6].
sedimentary PM is pure soot PM to ignore the influence of geometry size of filter in the process of sedimentary soot PM burning; b)microwave energy evenly distributed along the radial direction of filter; c)cerium-manga- -nese-based catalyst evenly distributed in the soot PM of diesel exhaust has no effect on filter porosity, only changes reaction activation energy; d)the airflow which flow through filter is incompressible flow, components of airflow meet the state equation of ideal gas in reaction, specific heat is constant; e) don't consider the influence of reaction caused by H2O, NOx and CO, the process of reaction includes only three first-degree reactions: C+O2→CO2,2C+O2→2CO,C+CO2→2CO; f) filter and surrounding environment without heat exchange, boundary is adiabatic and reaction is adiabatic processes; g) ignore the PM deposited in the filter hole of capture. 1.2 The mathematic model According to the physical model and assumptions, first to establish the balance of CO2 gas state material

In technologies used for machining metals, the fast deformation of materials is localized to a relatively narrow band, where, as a result of deformation work, temperature increases nearly adiabatically.
The material of the work piece is homogenous isotrope, the work piece and the tool are rigid, the material in the shear zone is plastic while it is flexible in the chip.
The plastic material hardens during cutting, but it softens as a result of temperature increase.
