AlB ¨ Al, A2B3,, A3B3, A3 to further narrow the search area, before the program in principle to determine the best. should be more comprehensive technical and economic evaluation and decision-making of the initial evaluation of the 6 possible access to the power source library Table 4 hydraulic and pneumatic grab performance comparison program. that in order to achieve efficient handling, hydraulic or power source in the form selection pressure. for further screening, take priority, there may wish to make a comparison of hydraulic and pneumatic (see Table 4) Table 4 shows: compared with pneumatic drive hydraulic transmission has obvious advantages are: power density, compact, light weight,[link widoczny dla zalogowanych], adjusting the speed performance, smooth operation,[link widoczny dla zalogowanych], reliable, self-lubrication. easy to implement complex control. pneumatic transmission clear advantage is : simple structure, easy maintenance, low cost. working life, the working medium (air) transmission simple and easy to obtain,[link widoczny dla zalogowanych], A concept into a hydraulic double-jaw or jaw grab, take two or more hydraulic cylinder. B3 conceived as a long pole loom hydraulic dual or multi-jaw grab jaw plates,[link widoczny dla zalogowanych], just the idea of a hydraulic cylinder into the hydraulic shear A3B grab, two hydraulic cylinders. Through the above analysis. After evaluation, screening identified Grab the three principles of the program, these three programs, Figure 6A1, A}, A garland Kids in the program can control the design plan for further qualitative analysis (see Table 5). derived from Table 5: AjB3 can better to meet the design requirements, the structure is slightly less complex; A2B3 not prevent leakage of the bulk critical performance requirements; A3B3 hydraulic cylinder journey, which is technically difficult to achieve. it is the best principle to finalize AIB3 I Shu meter Taiyuan Heavy Machinery Institute, the program 58 of more than 5 Conclusion 1996 is the use of design methodology and the creation of Development and Design Principles for grabs in the new design principle of the program were studied plane. in the design process should also pay attention to following points: (1 ) the evaluation process should make full use of the collective wisdom to improve the evaluation accuracy. In the qualitative analysis methods can not draw conclusions, the weighted method can be used for quantitative analysis. (2) compare time and time again, filter, is actually a step by step to find the weak links is an optimization process. (3) After determining the best design principles of the program, it also should make full use of design methodology and the creation of the basic principles of design innovation. For example, the structural design of the grab, to fully designer's creative play to determine the structural design of the variable element, the variable elements of change, innovation optimum design.
