ABSTRACT

Development and feasibility assessment of a rotational orthosis for walking with arm swing

 Interlimb neural coupling might underlie human bipedal locomotion, which is reflected in the fact that people swing their arms synchronously with leg movement in normal gait. Therefore, arm swing should be included in gait training to provide coordinated interlimb performance. The present study aimed to develop a Rotational Orthosis for Walking with Arm Swing (ROWAS), and evaluate its feasibility from the perspectives of implementation, acceptability and responsiveness. We developed the mechanical structures of the ROWAS system in SolidWorks, and implemented the concept in a prototype. Normal gait data were used as the reference performance of the shoulder, hip, knee and ankle joints of the prototype. The ROWAS prototype was tested for function assessment and further evaluated using five able-bodied subjects for user feedback. The ROWAS prototype produced coordinated performance in the upper and lower limbs, with joint profiles similar to those occurring in normal gait. The subjects reported a stronger feeling of walking with arm swing than without. The ROWAS system was deemed feasible according to the formal assessment criteria.

Aerodynamic analysis of a LMP1-H racing car by using Solidworks flow simulation

The paper reports on the use of integrated Computer Aided Design (CAD) and Computational Fluid Dynamic (CFD) tools within an undergraduate teaching and learning (T&L) environment. Solidworks and the embedded CFD are powerful tools to make students familiar with engineering design problems, in this case the definition within constraints of a body surface for Drag (D) and Lift (L) forces, and the way to progress through testing of concepts and solutions. The activity also promotes the understanding of the value of the details of a design, as geometries apparently very similar are shown to actually have very different drag and lift forces, and the limitation of computational tools, both because of the physics, as separated flows are difficult to be modelled, and the numeric, as proper mesh refinement and development of best practice approaches linked to accurate experiments are crucial to make simulations useful.

Static and dynamic performance evaluation of 3-DOF spindle head using CAD-CAE integration methodology

Accurate and rapid modelling and performance evaluation over the entire workspace is a crucially important issue in the design optimization of parallel kinematic machines (PKMs), especially for those dedicated for high-speed machining where high rigidity and high dynamics are the essential requirements. By taking a 3-DOF spindle head named A3 head as an example, this paper presents a feature-based CAD–CAE integration methodology for the static and dynamic analyses of PKMs. The approach can be implemented by four steps: (1) creation of a parameterized geometric (CAD) model with analysis features in SolidWorks; (2) extraction of the features from the CAD model using the Application Programming Interface (API) available in SolidWorks; (3) formulation of a CAD model in SAMCEF by mapping the configuration features from SolidWorks to SAMCEF; and (4) conversion of the analysis features into a scripting language named Bacon for Finite Element Analysis (FEA). The merit of this approach lies in that the FE model at different configurations can be updated automatically in batch mode, and PKMs having different topologies can be modeled with ease thanks to the down to link/joint level featuring. The experiment is also carried out to verify the effectiveness of the proposed approach.

Modelling of violin playing robot Arm with MATLAB/SIMULINK

In this research, we consider modeling of violin playing robot arm. MATLAB/SIMULINK are used for modeling of robot arm with seven degrees of freedom is considered, which is flexible than previously used robot arms with 6 joint for violin playing. Also, previous robot system which used Mitsubishi industrial robot arm (RV-2SD) is updated. In this model, torque, current consumption and voltage of each joint can be measured. Dynamixel-Pro from Robotis Co., Ltd. is used for the joints. This robot arm with seven joint has same range of movement (RoM) with human. This makes our designed robot good at violin playing. This paper presents basic violin playing technique, 3D modeling using Solidworks software, PID control system of servo motor using MATLAB/SimMechanics tool, and physical system of servo motor.

CFD analysis (SWFX) of micro hydro turbine used in a rural drinking W.T.P: A case study

Hydro turbine is the most critical component in small or micro hydropower plants as it affects the cost as well as overall performance. Hence, for the cost effective design of any new small or micro hydro project or for energy recovery plant from existing water infrastructure, it is very important to predict the hydraulic behaviour and efficiency of hydro turbine. Experimental approach of predicting the performance of hydro turbine is costly and time consuming compared to CFD approach that saves time-cost-effort. The aim of the paper is to predict the performance of a micro hydro turbine (MHT) using Solidworks-FloXpress (CFD analysis) and to validate the same with model testing results. To the best of the author’s knowledge this novel approach for CFD analysis of micro hydro turbine for energy recovery from drinking water pipeline is absent in renewable energy or fluid mechanics literature due to its assessment complexity.

Estimation of truck frame fatigue life under service loading

The article presents the methods for experimental and theoretical research of vibration loads and dynamic stresses of automobile frame. The comparative analysis of the finite element stress and acceleration is performed with SolidWorks and Ansys software with the use of resistive strain gages and g-meters data obtained during automobile road tests. Frame fatigue life calculation of using multibody dynamics model in FRUND software is given. Load-carrying structures of automobiles undergo external loads which are time- and frequency-variable, depending on velocity, current weight, road profile and other factors. Such loading mode provokes the occurrence of fatigue cracks, and their promotion can entail fracture. Thus, frames and load-carrying structures are subjects of cyclic loading tests purposed to estimate stress level and reliability of the structures and detect possible failures. The motion was considered for following road types: concrete road, smooth cobblestone road and special cobblestone profile. Road types and automobile velocities are corresponding to input data for dynamic simulation in FRUND multibody dynamics system.
