The development process of the knowledge-based engineering (KBE) system for structural size optimization external fixation device is presented in this paper. based on algorithms generative modeling, finite element model (FEM) analysis, and optimization. All these are integrated into CAD/CAM/CAE CATIA. initial CAD/FEM verified using experimental verification real design. Experimental testing don...

The absolute calibration of a piezoelectric transducer refers to the determination of the relationship between the electrical and acoustical quantities for a transducer coupled to a solid. It is shown how a well-characterized ultrasonic system, consisting of source,structure and receiver can be used to make such measurements for transducers operating as sources or receivers. Results are given, ...

An acoustic mixer for glass channel microfluidic systems is presented. An acoustic standing wave, perpendicular to the fluid flow, is generated by the excitation of a miniaturized piezoelectric transducer operated around 10 MHz. The transducer is fabricated into a planar printed circuit board structure, constituting the bottom channel wall, which makes the mixer simple to integrate with a wide ...

A coherent light beam is used to interrogate the focal region within a tissue-mimicking phantom insonified by an ultrasound transducer. The ultrasound-tagged photons exiting from the object carry with them information on local optical path length fluctuations caused by refractive index variations and medium vibration. Through estimation of the force distribution in the focal region of the ultra...

This paper is concerned with transfer characteristics of a pneumatic micrometer system with a negative feedback transducer. The system has two negative feedback pathes. One of them is based on the transfer characteristics of the feedback transducer which is introduced to linealize the transfer characteristic of the system and the other is caused by repulsive pressure force between nozzle and it...

In pushing and pulling wheeled carts, the direction of force exertion may, beside the force magnitude, considerably affect musculoskeletal loading. This paper describes how force direction changes as handle height and force level change, and the effects this has on the loads on the shoulder and low back. Eight subjects pushed against or pulled on a stationary bar or movable cart at various hand...

Purpose: The purpose of this study was to evaluate the occlusal force adjusting ability implant-supported overdenture (IOD) wearers, as compared with natural teeth and complete dentures. Methods: Subjects were those dentition (ND group; 19 subjects), overdentures (IOD 7 dentures (CD 14 subjects). asked hold test foods (peanuts biscuits mounted on a custom-made apparatus transducer) between thei...

This paper addresses the modeling of strains and forces generated by magnetostrictive transducers in response to applied magnetic elds. The magnetostrictive eeect is modeled by considering both the rotation of magnetic moments in response to the eld and the elastic vibrations in the transducer. The former is modeled with the Jiles-Atherton model of ferromagnetic hysteresis in combination with a...
