This paper aims at the problems of traditional compound pendulum jaw crusher including unreasonable structure design, heavy weight, low utilization of material and high cost, chooses moving jaw which is the key part of motion mechanism as the optimal design subject, uses finite element method, through statics analysis, obtains stress and displacement distribution of moving jaw that is under the action of maximum fracture force, realizes weak link and surplus part of primary structure. Based on the above-mentioned study, this article uses minimum weight of moving jaw as objective function, combines with structure characteristic of crusher, uses the ANSYS Parametric Design Language (APDL) to establish parameterization model, and combines with the optimal design module OPT, works out the minimum weight of moving jaw under the conditions of meeting intensity and stiffness. The result indicates that moving jaw is less than the original one by 27%, which saves material, reduces cost and weakens additional dynamic load that caused by inertial force of work mechanism, improves dynamics of mechanism to a cert extent, reduces the vibration of mechanism and the wear of part, and extends product service life. © (2013) Trans Tech Publications, Switzerland.

Aiming at the low responding capability for customer requirements in single modular or parametric platform design, a multiobjective planning method for flexible product platform based on conjoint analysis and quantitative indices was proposed. By analyzing on platform's leveraging characteristics and optimization trends, a design process model for flexible product platform was constructed. Through introduction of conjoint analysis, the importance degree of product attributes and utilities of attribute levels for customer satisfaction were achieved. Quality function deployment was applied to acquire the association matrix between product attributes and internal components. The quantitative platform generality index and product diversity index were proposed to construct a two-objective optimization model for flexible platform, which was solved by multi-objective evolutionary algorithms. The quantitative analysis modeling and multiobjective optimization for the flexible platform design were realized. Effectiveness of the proposed method was illustrated by the leveraging planning for large-scale hydraulic support platform.

The stability of high-speed spindle system affects the surface finish and tool life directly, which is an important factor to evaluate its performance. Meanwhile, the spindle dynamics and cutting stability are affected by the structure and dynamics of spindle-holder-tool joints significantly. The joints are simplified as the distribution-spring, and the FEM modeling process of spindle system is proposed based on the thought of parallel rotor system. Taking a vertical machining center as example, the effectiveness of the modeling method is verified. Starting from the stability evaluation criteria and different ways of getting FRF, the influence factors of unconditional and conditional stability regions are analyzed. Based on the proposed model, the influence laws of cutting stability on cutting force amplitude and speed are characterized by the three-dimensional lobes, limit cutting depths and lobe intersections, which provide the theoretical basis for optimizing the processing and improving the cutting stability. © JVE INTERNATIONAL LTD.

The melting process for ZG30MnSi with the medium frequency induction furnace was presented. Through measures such as the quality control of raw materials, the selection of chemical composition, and the content control of deoxidation aluminum and residual aluminum in molten steel in the final deoxidation stage, high-quality molten steel was obtained. The casting defects such as porosity, inclusions etc. were effectively reduced, and the internal structure of the casting was refined. The casting has excellent mechanical properties, which are better than those of national standards.

To solve the product data consistency problem which is caused by the portable system that cannot conduct real-time update of product data in mobile environment under the mass customization production mode, a new product data optimistic replication method based on log is presented. This paper focuses on the design thinking provider, probing into a manufacturing resource design thinking cloud platform based on manufacturing resource-locating technologies, and also discuss several application scenarios of cloud locating technologies in the manufacturing environment. The actual demand of manufacturing creates a new mode which is service-oriented and has high efficiency and low consumption. Finally, they are different from the crowd-sourcing application model of Local-Motors. The sharing platform operator is responsible for a master plan for the platform, proposing a open interface standard and establishing a service operation mode. © 2013 Zhe Wei et al.
