Abstract:

Orthoplanar springs are single-component compliant mechanisms that can be fabricated from sheet material and undergo deflection orthogonal to the plane of the mechanism. They are useful in applications where spatial constraints are significant. An Euler spiral is a curve whose curvature is linearly proportional to the arc length allowing for the curve to assume a flat position under a load. In this work, orthoplanar spring and Euler-spiral concepts are synthesized to create a single-component spring mechanism that lies flat under a load. Where traditional planar springs under a load will take

Abstract:

The energy storage technology is playing an important role in improving power grid stability. Aiming to the randomness and intermittent characteristics of wind power generation, the paper proposed a scheme of mechanical elastic storage energy and power generation system based on flat spiral spring. The flat spiral spring, which is the core component in the system, is selected as the research object, and the mechanical model and the finite element model is created. The geometric parameters of spring are determined. The maximum deformation and the stress distribution of spring are obtained. More

Curved pipe systems are widely used in mechanical engineering, the nuclear industry, offshore oil production, and aerospace engineering. The purpose of the work is to study small vibrations of a viscoelastic helical spring. Small vibrations of a thin curved rod, the elastic line of which is a flat curve and one of the main directions of the cross-section of which lies in the plane of the curve, break down into two types: vibrations with displacements in the plane of the curve and with displacements perpendicular to the plane of the curve.

Abstract:

The paper deals with the analytical modelling of a shape memory alloy Negator spring. Negator springs are spiral springs made of strip metal wound on the flat with an inherent curvature such that, in repose, each coil wraps tightly on its inner neighbour. This configuration allows a constant force mechanical response and very long strokes, limited mainly from the total length of the spring. The authors investigate the behaviour of the spring made of a shape memory alloy (SMA). The intrinsic characteristic of SMA is to have two different elastic moduli at different temperatures. This difference

Abstract:

A-hoe blades consisting of a share and a frog are used as working organs of cultivators. Main characteristics of share are the expansion angle of blades and the crumbling angle. For falling away of cut weed, the expansion angle should not exceed 70 degrees. The higher crumbling angle provides more intensive effect on the soil. There are also negative effects in working process: soil displacement aside, formation of grooves, removal of moist soil to the daylight surface. As far as copying elements of cultivator are separated by a distance from working organs, the variability of operating depth

Abstract:

Insects exhibit excellent maneuvers such as running and flying despite their small bodies; therefore, their locomotion mechanism is expected to provide a design guideline for micromachines. Numerical simulations have been performed to elucidate this mechanism, whereby it is important to develop a model that is physically identical to the target insect’s parts to reproduce kinematic dynamics. In particular, in flight, the shape and mass of wings, which flap at high frequencies, are significant parameters. However, small insects such as fruit flies have small, thin, and light wings; thus, their

Abstract:

The central, spheroidal component of spiral galaxies is frequently found to be “box- or peanut” (b/p) shaped. More than 30% of edge-on galaxies may show this phenomenon (Dettmar 1995). To explain this large frequency a very common process for the origin of this specific shape is required. N-body simulations have shown that this can be attributed to instabilities and resonances caused by bars in spiral disks (e. g., Combes et al. 1990, Raha et al. 1991).Previous statistics (Jarvis 1986, Shaw 1987, de Souza & dos Anjos 1987) are hampered by the low dynamic range of the photographic material
