RISAnalysis of Force Distribution and Motion Characteristic of Hybrid-Driven Tensegrity Parallel Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tensegrity parallel mechanisms is a novel spatial structure composed of cable-based and rigid-based chains, which is characterized by lightweight, multi-stability, high precision, good stiffness, and high load-bearing ...
Responses of Linear and Nonlinear Oscillators to Fractional Gaussian Noise With Hurst Index Between 1/2 and 1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The responses of linear and nonlinear oscillators to fractional Gaussian noise (fGn) are studied. First, some preliminary concepts and properties of fractional Brownian motion (fBm) and fGn with Hurst index 1/2<H<1 ...
Stationary Response of a Class of Nonlinear Stochastic Systems Undergoing Markovian Jumps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Systems whose specifications change abruptly and statistically, referred to as Markovianjump systems, are considered in this paper. An approximate method is presented to assess the stationary response of multidegree, ...
Stationary Response of Multidegree-of-Freedom Strongly Nonlinear Systems to Fractional Gaussian Noise
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stationary response of multidegree-of-freedom (MDOF) strongly nonlinear system to fractional Gaussian noise (FGN) with Hurst index 1/2 < H < 1 is studied. First, the system is modeled as FGN-excited and -dissipated ...
Flowfield and Performance Analysis of a Three-Dimensional TBCC Exhaust Nozzle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compared to other engines, turbine-based combined cycle (TBCC) engine is one of the most suitable propulsion systems for hypersonic vehicle. Because of its fine reusability, wide flight envelope, and safety margins, TBCC ...
A Method to Determine the Constitutive Parameters of Hyperelastic Films Based on Spherical Indentation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An indentation method to determine the properties of hyperelastic thin films is proposed, which is to use a spherical indenter to indent on the film with a small circular hole in the center. During this progress, there ...
A New Method for Motion-Decoupling Identification of Parallel Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Motion-decoupling identification (MDI) for parallel mechanism (PM) is a significant issue in the analysis and design of PMs. In general, people use the Jacobian matrix method to determine whether a given PM has motion-decoupling ...
Dilatancy Equation for Rockfill Materials under Three-Dimensional Stress Conditions
Publisher: American Society of Civil Engineers
Abstract: The intermediate principal stress ratio b has a significant influence on the dilatancy behaviors of rockfill materials. The dilatancy equation is defined as a function of the dilatancy dg and the stress ratio η. To investigate ...
Performance Analysis and Optimal Design of a Novel Schöenflies-Motion Asymmetric Parallel Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Since previous studies of parallel mechanisms (PMs) have tended to favor symmetrical overall configuration to obtain relatively stable kinematic and dynamic performance and to satisfy isotropic requirements. The analysis ...
Experimental Study on Combustion and Heat Transfer Characteristics of Li/SF6 based on Unmanned Underwater Vehicle Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Li/SF6 combustion reaction can provide power for unmanned underwater vehicle (UUV) due to the advantages of high heat release and no gaseous combustion products. Exploring the combustion and heat transfer characteristics ...
