Abstract The staggered herringbone chaotic micromixer has been designed based on the use of modular method and orthogonal experiment. With the modular method, the geometry of the micromixer was divided into straight channels and mixing units alternately. The mixing units were designed with orthogonal experiment. The aspect ratio of the herringbone to the microchannel (r1), the ratio of the width of herringbone to the spacing of between adjacent two herringbones (r2) and the width of the herringbone (r3) were investigated. The optimal outputs were r1 = 1:3, r2 = 1:1, and r3 = 50 µm. The micromixer was fabricated with two steps lithography method based on the presented optimal parameters, and the material of the micromixer was polydimethylsiloxane (PDMS). The optimized design method is proven to be an effective way for rapid design of the staggered herringbone chaotic micromixer.

In this article, the author examines the modular methodology for designing a suit as a way to transform the shape and structure of a suit with minimal expenditure of time and financial resources, which determines the great potential of the modular methodology in the field of suit design. The main task of the study is to provide analytical substantiation of the existing modular design of a suit from lace fabrics and the development of modular design of a suit from lace, lace fabrics and lace-like structures. The adaptation of a modular methodology in designing a suit using lace, lace fabrics and lace-like structures was carried out for the subsequent development and improvement in the design of costumes from lace, which was chosen as the basis of the empirical design method. This allows the research results to be included in the designer’s scientific base for developing a suit from modules using additive technologies. In the article, the author discloses the principles of designing a suit from lacy modular elements by changing the configuration of modules (flat module, volumetric module), which, in turn, are divided into subcategories. The systems for connecting modules into a canvas (in accordance with the geometry of the ornamental mesh, based on the theory of A.V. Shubnikov; according to the principle of unsystematicity and the principle of linear arrangement of modules) and the types of connecting modules in a suit made of lace and lace-like structures (“butt”, “overlay”, “оn the edge”, “figure”). As a result of the study, an algorithm for the method of modular design of costumes from lace, lace fabrics and lace-like structures is proposed, on the basis of which the author's sketches are presented using a modular method of designing costumes from lace fabrics.

Study Results

The values of Many parameters which involve in the design of fluid film journal bearings mainly depend on the bearing applied load when using the conventional design method to design the journal bearings, in this study, as well as applied bearing load, the dynamic response and critical speed have been used to calculate the dimensions of journal bearings. In the field of rotating machine, especially a heavy-duty rotating machines, the critical speed and response are the main parameters that specify bearing dimensions. The bearing aspect ratio (bearing length to bore diameter) and bearing clearance have been determined based on rotor maximum critical speed and minimum response displacement. The analytical solution of rotor Eq. of motion was verified by numerical solution via using ANSYS Mechanical APDL 18.0 and by comparing the numerical solution with the preceding study. The final study results clearly showed that the bearing aspect ratio has little effect on the critical speed, but it has a high effect on the dynamic response also the bearing clearance has little effect on the critical speed and considerable effect on the dynamic response. The study showed that the more accurate values of bearing aspect ratio to make the response of rotor as low as possible are about 0.65 - 1 and bearing percent clearance is about 0.15 - 0.2 for different rotor dimensions.

Modular design, Axiomatic design (AD) and Theory of inventive problem solving (TRIZ) have been increasingly popularized in concept design of modern mechanical product. Each method has their own advantages and drawbacks. The benefit of modular design is reducing the product design period, and AD has the capability of problem analysis, while TRIZ’s expertise is innovative idea generation. According to the complementarity of these three approaches, an innovative and systematic methodology is proposed to design big complex mechanical system. Firstly, the module partition is executed based on scenario decomposition. Then, the behavior attributes of modules are listed to find the design contradiction, including motion form, spatial constraints, and performance requirements. TRIZ tools are employed to deal with the contradictions between behavior attributes. The decomposition and mapping of functional requirements and design parameters are carried out to construct the structural hierarchy of each module. Then, modules are integrated considering the connections between each other. Finally, the operation steps in application scenario are designed in temporal and spatial dimensions. Design of cutter changing robot for shield tunneling machine is taken as an example to validate the feasibility and effectiveness of the proposed method.
