Free-form and bionic spatial shells are popular in the area of spatial structures. Scallop-shaped surface is the product of evolution and a kind of spatial shells that can satisfy the mechanical requirements. Based on the scallop-shaped lattice shells, this paper focused on the optimization of geometric parameters. The principle of minimum strain energy was applied to conclude the influence law of the geometric parameters on mechanical properties. Finally the optimal values of geometric parameters were obtained. The results show that the optimization of geometric parameters presents the integrated significance to improve scallop-shaped lattice shells.

Explaining how to set up configuration model from the Angle of product family, for the composition of product configuration model of product family structure was analyzed, put forward the definition of product family configuration unit, and used it as the basic elements of product family configuration model. Using various granularity of product family configuration units set to do the unified expression for function, the principle and structure of all products contained in the product family. And did further analyze for the characteristic, types, and associated constraints of product family configuration units. Finally, described the modeling process of product family configuration model. Do verification by the dumper.

In order to realize the integration of electronic circuits and avoid the electromagnetic interference between mutual inductance components and periphery circuit, the paper put forward a new kind of coupling element-mutual capacitance components, which were dual with mutual inductance components, according to the duality principle and the gyrator application theory. First of all, the paper used the basic electrical components-operational amplifier, resistance and capacitor to set up the circuit implementation model of mutual capacitance component, and then selected device parameters to execute theory calculation. On the basis of the previous step, a simulation software-PSpice, was used to simulate the model. Finally, comparison of two different groups of simulation data showed the correctness of the circuit model and the feasibility of the mutual capacitance component.

Large antenna is susceptible to external influence in the actual work load; it causes the azimuth change and affects the radar work. In order to solve this problem, Adams and Simulink co-simulation method and the antenna board PID control are used. Simulation results show that angular variation of the callback can be achieved, and the response time can be greatly reduced less than 2 seconds. Keywords: Panel Antenna, Co-simulation, Azimuth control

Considering the problem that current configuration design method is mainly faced for professionals, based-on the analysis of different customers’ respective understanding of products and configuration methods, a function-structure configuration method of mass customization product is proposed according to the general design process from function to structure. Meanwhile, in the configuration real-time related analyses and advices are provided customers, which would guide customers to complete configuration design of personal product rapidly. Finally, a wheel lock configuration case is given to illustrate the proposed method.
