Design Idea

Powertrain mounting bracket is a vital part in the car, its strength is more important for the vehicle lifetime, and lightweight is becoming the aim of structure design. According to the optimization design idea, a common formula of size optimization was deduced. And the structure of the mounting bracket was analyzed by using Optistruct software and the bracket in real work condition was studied. In the premise of meeting the stress, the optimal design of the bracket was finished. And the result show that the optimal design is right and reasonable, the quality of optimized bracket was reduced 37.28%, and achieved good results.

CAE analysis on engine hood is conducted under five common working conditions in this paper. Considering lightweight material application status at present, three material substitution plans are determined. To make full use of material properties, draw up size optimization scheme based on volume target and displacement and frequency constraints. Determine the optimum thickness by conducting size optimization on engine hood with optimization tool-Optistruct, so as to realize lightweight design.Based on the introduction of a evaluation method for lightweight scheme selection based on overall satisfaction and taking the factors of weight, cost and performance into consideration, at last, determine the best lightweight scheme.

Based on the characteristics of steel structure of the furnace, a generic finite element model, automatic loading, analysis and post-processing was achieved by ANSYS-APDL firstly. Then taking the sizes of profile as design variables and total mass as objective function, the size optimization design on steel structure was developed by means of two-level algorithm based on discrete variable.

Ansys Workbench

The role, principle and characteristics of the rubber chain attached board used in steel wire knitting machine were analyzed in this paper. A new kind of attached board with reasonable structure was designed through comparison of several design schemes. Eventually, through finite element analysis and size optimization design based on Workbench, the structure size of attached board was optimized and the whole strain, the maximum equivalent stress and the minimum safety factor were calculated. At the same time, new design ideas are also provided for the development of steel wire knitting machine to save materials and reduce cost.

Distributed Logic

In this paper, we first employ an efficient approach to reduce the time to construct a codeword. With this codeword, a novel VLSI architecture is proposed to realize highspeed Variable Length Coding (VLC). In order to combine with other circuits using cell-based design, we adopt distributed logic rather than memory devices (ROM, PLA) for the implementation. In this architecture, the VLC coding scheme is partitioned into two parts, one is the codeword length and order index for bit control, another is the codeword bank for actual codeword generation. The advantage is that the circuit size of the proposed method can be reduced, where the transistor count of proposed method is only 1/2 and 1/4 of that of ROM- based and PLA-based in average, respectively.
