Design and Analysis of Nano-Vibratory Beam Gyroscope
Abstract: This paper presents the modeling and analytical simulation task of a nano cantilever beam gyroscope. Micro/nano gyroscope as an effective rate measurement sensor is of extreme importance in several modern equipments including aircrafts, satellites and even in small cameras. Several types of such gyroscopes are in use and various research simulations were performed over the last one decade. Compared to tuning fork and ring type, the beam type gyroscopes are …

Comparison of Existing Experimental Results with Different Types of Simulation Software for Transmission Loss Estimation of Muffler
Abstract: Acoustic Muffler’s characteristics are calculated by Transmission Loss and Insertion Loss. Single expansion chamber is generally used as noise reduction elements in exhaust systems. To quantify its effectiveness, transmission loss is commonly used as a parameter comparing the transmitted with incident sound pressure level. Mufflers are typically arranged along the exhaust pipe as the part of the exhaust system of an internal combustion engine to reduce its noise. Tao and …

Design and Analysis of Cantilever Optomechanical Resonator
Abstract: Solar energy harvesting is one of the leading branches of research in the world. Sun is the greatest source of energy on earth. A lot of techniques are developed in order to tap this energy as much as possible. Optomechanical resonance is a very novel approach for achieving this objective. Solar energy is used to heat a cantilever beam which vibrates at its natural frequency. Due to vibration the beam …

Development of a Novel Hybrid Precision Positioning Table Utilizing Stepper Motor and Amplified Piezo Actuator
Abstract: This research paper presents a unique actuating method for a single-axis precise positioning system using a combination of stepper motor and amplified piezo actuator (APA). The adopted method is to employ combination of two separate stages one above the other to achieve the precise positioning. The bottom stage uses a stepper motor (SM) coupled to a fine lead screw for coarse positioning stage (CPS). The secondary stage (SS) is mounted …

Experimental Characterization of Amplified Piezo Stack Actuator for Controlled Actuation of Microgrippers
Abstract: This paper presents the results of experimental characterization of an Amplified Piezoelectric Actuator (APA) under quasi-static operation. The data obtained from the study will be used for designing a control system for a microgripper which will be actuated using the APA. An improved measurement method suited for static force measurement was devised. The study identified relation between force applied by the piezo-actuator in relation to the applied voltage and resultant …

V-Belt Fatigue Life Prediction
Abstract: The system of the V-belt drives was studied by means of the similarity theory in this research, and the major factors and the basic dimensions which would affect the fatigue life of V-belt were ascertained. Then the prediction hypothesis of the V-belt’s fatigue life was deduced. The theory and the method proposed in this paper would optimize testing of the fatigue lives of V-belts, and the test workload would be …
