Mechanical Design Problem

A new three degree-of-freedom (3DOF) torque feedback wrist is being developed to be added to an existing 3DOF force feedback haptic device. It is difficult to find a satisfactory solution to the mechanical design problem, mainly because of the required large rotational workspace and severe weight constraints. This work proposes an alternative design strategy based on user perception, which allows simplification of the mechanics. The proposed approach consists of substituting the last rotational DOF of the wrist with a pseudohaptic DOF. Thanks to specially designed visuotactile cues, the pseudohaptic DOF is integrated with the active DOF into the same device, being able to generate free motion and collision detection perception to the user. This approach provides for simpler kinematics, lightweight designs, lower inertias, and less friction, which are key advantages for the inclusion of torque feedback into force feedback devices.

Mechanical Design Problem

Abstract This paper studies planar motion approximation problems from a computational geometric perspective and develop a computational geometric structure that can be used for mechanical motion synthesis. This allows for development of computational algorithms and software systems to support the mechanical design activity. The approach uses an orientable kinematic mapping to transform the mechanical design problem into a curve design problem in the space of the mapping. The curve design problem for synthesis of an analytic motion is carried out by Hermite interpolation. In case of a mechanical linkage, however, the Hermite interpolation is combined with a first-order curve fitting procedure for synthesizing the motion.

Mechanical Design Problem

A novel application to mechanical optimal design is presented in this paper. Here, an evolutionary algorithm, called mixed-integer differential evolution (MIHDE), is used to solve general mixed-integer optimization problems. However, most of real-world mixed-integer optimization problems frequently consist of equality and/or inequality constraints. In order to effectively handle constraints, an evolutionary Lagrange method based on MIHDE is implemented to solve the mixed-integer constrained optimization problems. Finally, the evolutionary Lagrange method is applied to a mechanical design problem. The satisfactory results are achieved, and demonstrate that the evolutionary Lagrange method can effectively solve the optimal mechanical design problem.

Household electric blankets are widely used in China, but the problem of quality and safety is also more prominent, which is a serious threat to the health and safety of consumers. The structure characteristics and working principle of household electric blanket are analyzed. The hazards in the each stage of full life cycle are identified, including the stages of designing, manufacturing, packaging, transporting, utilizing and recycling. Hazard identification of each stage is made with methods of scenario analysis, safety check list, fault hypothesis analysis, hazard and operability analysis, failure mode and effect analysis and fault tree analysis, respectively.

Perhaps no area of yachting has reached harder for technology, and grasped less, than sail shape design. The combination of the obsession with secrecy, the background and training of those in the business, the economic characteristics of the marketplace, and the intractability of the problems is formidable and has made scientific sail engineering a grail. This paper will not solve those problems; rather it reports on an attempt to begin an attack on the fundamental problems and to report the outcome. Thus, the paper will: - describe the fundamentals of the sail shape design problem so that practical sailors can, with some study, grasp the nature and difficulty of the problem to the extent that claims can be evalu­ated thoughtfully; and - report on a research program intended to put the art onto a solid engineering basis by formulating the problem and beginning work on solutions.

A software quality evaluation method for control system based on the extension engineering analysis method is proposed. The evaluating index system of software quality evaluation for control system was constructed. The matter elements models were constructed, and the goodness of mechanical design scheme was computed by using goodness evaluation method based on correlation function calculation. Then the pros or cons of system to be evaluated were determined by comparing the goodness value of each evaluation grade. Finally, the practical application showed that the evaluation method was scientific, clear, and effective and had good practicality.
