Computer-aided design procedures have been developed for the optimum mass distribution of the links of high-speed spherical four-bar linkages. The analysis, which includes a quadratic-programming technique, allows an optimum trade-off between shaking forces, shaking moments, bearing reactions, and input-torque fluctuation. The results are illustrated in the case of a Hooke joint and a wobble-plate linkage.

Abstract Recently, there is an increasing interest in design of circular weft jacquard because of the pursuit of fashion and comfort. Aiming at the complexity of the computer-aided design method of the existing circular weft-knitted jacquard fabrics, which is not conducive to the rapid design and intelligible for designers, a design method was proposed to transform pattern notation into knitting diagram efficiently, which was based on knitting rules and its creation as a set of jacquard modules. Knitting characteristics of jacquard fabrics were studied as a precondition. On this basis, the design procedures of jacquard modules were analyzed and illustrated by taking tricolor bird's eye backing jacquard as an example. Jacquard modules with various jacquard effects were designed and stored in a jacquard module database. To mathematically describe pattern notation, knitting diagram, and jacquard module, two-dimensional matrixes were established by the method of mathematical modeling, and a corresponding algorithm for the transformation of the pattern to knitting information according to the knitting rules of jacquard modules, which can be applied to ordinary jacquard fabrics was summarized. The project of tricolor circular weft-knitted jacquard with bird's eye in the reverse and four-color air-layer jacquard were taken for instance to verify the models and algorithm. The results obtained show that the approach can efficiently and conveniently realize the designation and machine-knitting of weft-knitted jacquard fabric, which provide a theoretical basis and notation of modeling for the computer-aided design of circular weft-knitted jacquard fabrics.

Recently, studies concerning motorcycle have been an overwhelming area of research interest. As an alternative to the real world assessment, researchers have utilized motorcycle simulator as a workstation to conduct studies in the motorcycle niche area. This paper deal with the development of a new motorcycle simulator named Semi-Interface Motorcycle Simulator (SiMS). Combination of Computer Aided Design (CAD) and Finite Element Analysis (FEA) software made it possible to design and simulates the motorcycle simulator’s conceptual design before being fabricated. The SiMS setup not only provides a near-to-real and immerse motorcycle riding experience on a super sport motorcycle model, but it also allows safer high speed motorcycle simulations to be conducted in a controlled environment that is portable and ergonomically easier to transport to various venues.
