This paper presents the design and application of a lever coupling mechanism to improve the shock resistance of a dual-mass silicon micro-gyroscope with drive mode coupled along the driving direction without sacrificing the mechanical sensitivity. Firstly, the mechanical sensitivity and the shock response of the micro-gyroscope are theoretically analyzed. In the mechanical design, a novel lever...

This paper presents the development steps of a fast manipulator, up to the building of the experimental device, in a context of mechatronic design which implies the integration of several engineering disciplines. High performance of the manipulator has been achieved by means of the suitable integration of the mechanical part and the drive part. For the mechanical part we choose a 3-dof parallel...

Mechanical stress can drive chemical reactions and is unique in that the reaction product can depend on both the magnitude and the direction of the applied force. Indeed, this directionality can drive chemical reactions impossible through conventional means. However, unlike heat- or pressure-driven reactions, mechanical stress is rarely applied isometrically, obscuring how mechanical inputs rel...

In the past decade the applicability of belt-drives has been extended significantly due to their increased reliability. With automotive engines it is now common to join a large number of belt-drives into a single, long belt-drive with several tensioner pulleys. However, these belt-drives can exhibit complex dynamic behaviors; therefore it is very important to predict the dynamics response of su...

CIRCUIT CELLAR www.circuitcellar.com The mechanical components that make up robots aren’t getting much cheaper. That’s the bad news. The good news, of course, is that electronics and processors continue their steady march toward higher performance and lower cost. As an engineer, you have to figure out how to use the extra resources and capabilities most effectively. In some cases, extra process...

Atomically precise manufacturing systems, such as those described in Nanosystems [1], will utilize molecular motors and actuators that drive components to perform useful work. The conversion of electrical and chemical energy into mechanical motion is facilitated by the use of gears, bearings, drive shafts, springs, and so forth, to direct the motion of components and minimize energy losses. Thu...

In the field of mechanics, it is a long standing goal to measure quantum behavior in ever larger and more massive objects. It may seem like an obvious conclusion now, but up until recently it was not clear whether a macroscopic mechanical resonator – built up from nearly 10 atoms – could be fully described as an ideal quantum harmonic oscillator. With recent advances in the fields of optoand el...
