  • Dislocation Formation From a Polycrystal Free-Surface مهر ۱۸, ۱۳۹۷
    The introduction of a dislocation from the free-surface of a grain A of a polycrystal has been investigated from the theoretical point of view. Assuming two disclination dipoles are lying in a high angle boundary separating the corresponding grain A and a neighbor grain B, the equilibrium position of the dislocation has been determined in […]
  • Machine Learning-Driven Real-Time Topology Optimization Under Moving Morphable Component-Based Framework مهر ۱۳, ۱۳۹۷
    In the present work, it is intended to discuss how to achieve real-time structural topology optimization (i.e., obtaining the optimized distribution of a certain amount of material in a prescribed design domain almost instantaneously once the objective/constraint functions and external stimuli/boundary conditions are specified), an ultimate dream pursued by engineers in various disciplines, using machine […]
  • Ron Resch Origami Pattern Inspired Energy Absorption Structures مهر ۱۳, ۱۳۹۷
    Energy absorption structures are widely used in many scenarios. Thin-walled members have been heavily employed to absorb impact energy. This paper presents a novel, Ron Resch origami pattern inspired energy absorption structure. Experimental characterization and numerical simulations were conducted to study the energy absorption of this structure. The results show a new collapse mode in […]
  • Specific Adhesion of Finite Soft Elastic Solid مهر ۹, ۱۳۹۷
    Specific adhesion of soft elastic half spaces via molecular bond clusters has been extensively studied in the past ten years. In this study, the adhesion of a soft elastic solid with finite size is considered aiming to investigate how their size and shape may affect the adhesion strength. To model this problem, plane strain assumption […]
  • Identification of Plastic Properties From Conical Indentation Using a Bayesian-Type Statistical Approach مهر ۹, ۱۳۹۷
    The plastic properties that characterize the uniaxial stress–strain response of a plastically isotropic material are not uniquely related to the indentation force versus indentation depth response. We consider results for three sets of plastic material properties that give rise to essentially identical curves of indentation force versus indentation depth in conical indentation. The corresponding surface […]
  • Closed-Form Solution of Road Roughness-Induced Vehicle Energy Dissipation مهر ۹, ۱۳۹۷
    A major contributor to rolling resistance is road roughness-induced energy dissipation in vehicle suspension systems. We identify the parameters driving this dissipation via a combination of dimensional analysis and asymptotic analysis. We begin with a mechanistic model and basic random vibration theory to relate the statistics of road roughness profile and the dynamic properties of […]

  • Development of an Insect-Inspired Hexapod Robot Actuated by Soft Actuators مهر ۱۸, ۱۳۹۷
    Insects are one of the most diverse group of animals on the planet and are almost ubiquitous. Their walking locomotion has inspired engineers and provided effective solutions for designing transport methods for legged robots. In this paper, we introduce a hexapod walking robot that mimics the design and walking motions of insects. The robot is […]
  • Spring-Assisted Motorized Transmission for Efficient Hover by Four Flapping Wings مهر ۱۳, ۱۳۹۷
    Elastic storage has been reported to help flying insects save inertial power when flapping their wings. This motivates recent research and development of elastic storage for flapping-wing micro air vehicles (fwMAVs) and their ground (tethered) flight tests. The previous designs of spring-loaded transmissions are relatively heavy or bulky; they have not yet been adopted by […]
  • Micro-Assembly Sequence and Path Planning Using Subassemblies مهر ۱۳, ۱۳۹۷
    This paper presents a novel assembly sequence planning (ASP) procedure utilizing a subassembly based search algorithm (SABLS) for micro-assembly applications involving geometric and other assembly constraints. The breakout local search (BLS) algorithm is adapted to provide sequencing solutions in assemblies with no coherent solutions by converting the final assembly into subassemblies which can be assembled […]
  • Efficient Collision Detection Method for Flexure Mechanisms Comprising Deflected Leafsprings مهر ۹, ۱۳۹۷
    When designing and optimizing spatial flexure mechanisms, it is hard to predict collision due to 3D motion and large deformations, which compromises the utilization of spatial freedom. A computationally efficient collision test is desirable to assure that feasible mechanism designs are found when algorithmically optimizing the shape of elastic mechanisms, which are prone to collision. […]
  • Dexterous Workspace Optimization for a New Hybrid Parallel Robot Manipulator مهر ۹, ۱۳۹۷
    In this paper, a new hybrid parallel robot (HPR) manipulator is introduced. First three kinematic limbs of six-legged general Stewart platform (6DOF GSP) manipulator are disconnected. Afterward, each passive universal joint of remaining three-legged parallel manipulator (three-UPS) is mounted at the center of each second passive revolute joint of RPR planar parallel manipulator (3DOF PPM) […]
  • Cooperative Robot Exploration Strategy Using an Efficient Backtracking Method for Multiple Robots مهر ۹, ۱۳۹۷
    This paper presents a cooperative robot exploration (CRE) strategy that is based on the sensor-based random tree (SRT) star method. The CRE strategy is utilized for a team of mobile robots equipped with range finding sensors. Existing backtracking techniques for frontier-based (FB) exploration involve moving back thorough the previous position where the robot has passed […]
  • Twisting and Tilting Rotors for High-Efficiency, Thrust-Vectored Quadrotors مهر ۹, ۱۳۹۷
    A mechanism consisting of twisting and tilting joints is introduced to provide omnidirectional thrust-vectoring capabilities to a quadrotor system. This mechanism eliminates mechanical constraints and kinematic singularities to provide full directional authority to all four individual thrust vectors. The presented system fully decouples position and attitude dynamics to overcome the intrinsic maneuverability limitations of traditional […]
  • Accuracy Analysis of Redundantly Actuated and Overconstrained Parallel Mechanisms With Actuation Errors مهر ۳, ۱۳۹۷
    A general accuracy analysis method of redundantly actuated and overconstrained parallel mechanisms is proposed. Coupled effects of actuation errors and internal elastic forces arose from the elastic deformation are both considered. The accuracy analysis approach is based on the Lie-group theory and screw theory, and it includes three steps. First, stiffness matrices of serial legs […]
  • Type Synthesis of Parallel Mechanisms With a Constant Jacobian Matrix مهر ۳, ۱۳۹۷
    Jacobian matrix plays a key role in the analysis, design, and control of robots. For example, it can be used for the performance analysis and evaluation of parallel mechanisms (PMs). However, the Jacobian matrix of a PM generally varies with the poses of the moving platform in the workspace. This leads to a nonconstant performance […]
  • A Three-Dimensional Printed, Nonassembly, Passive Dynamic Walking Toy: Design and Analysis شهریور ۳۰, ۱۳۹۷
    In this paper, we present the redesign and analysis of a century old walking toy. Historically, the toy is made up of two wooden pieces including a rear leg and a front leg and body (as a single piece) that are attached to each other by means of a pin joint. When the toy is […]
