The work aims to present a novel press system, and to investigate its feasibility by performing a kinematic study. Firstly, the new design is proposed, which is composed by a motor, a constant speed coupling, a gear reducer, a generalized Oldham coupling, and a slider-crank mechanism. Secondly, its structural sketch is drawn, and its kinematic dimensions are obtained by studying its motion geometry. Then, a design example is given for illustration. Moreover, the solid model of the design is established, and then the validity of the design is verified by kinematic simulation using ADAMS software. Finally, the effects of different link ratios on the output motion are examined by conducting a number of simulations. The results of simulations show that the new design can produce more flexible output motion than a mechanical press. In addition, it has the advantages of lower cost, high reliability, and lower energy consumption, compared to a servo press.

Energy Absorbing

Three finite element models of bus with difference types of cant rail joint were developed and the rollover crashworthiness of buses was simulated by LS_DYNA according to ECE R66. The calculation technique was validated by the tests of three separate specimens, which were extracted from the bus superstructure. The velocity of bus just before impact for rollover, were calculated using ADAMS software and then used as initial condition for the LS_DYNA analysis. No intrusion was found in the residual space of three bus models during rollover test simulation. The energy absorbing capacity and distortion configuration were investigated. The simulation results shown that the cont rail joint structure played an important part in energy absorbing during bus rollover accident, and would contribute to some design guidelines for bus rollover crashworthiness.

Novel Concept

In this paper, a novel concept on the design of a broadband printed Yagi antenna for S-band wireless communication applications is presented. The proposed antenna exhibits a wide bandwidth (more than 48% fractional bandwidth) operating in the frequency range 2.6 GHz–4.3 GHz. This is achieved by employing an elliptically shaped coupled-directive element, which is wider compared with other elements. Compared with the conventional printed Yagi design, the tightly coupled directive element is placed very close (0.019λ to 0.0299λ) to the microstrip-fed dipole arms. The gain performance is enhanced by placing four additional elliptically shaped directive elements towards the electromagnetic field’s direction of propagation. The overall size of the proposed antenna is 60 mm × 140 mm × 1.6 mm. The proposed antenna is fabricated and its characteristics, such as reflection coefficient, radiation pattern, and gain, are compared with simulation results. Excellent agreement between measured and simulation results is observed.

Simulation Results

Although many dynamic solvers are available for planar mechanisms, there is no readily accessible static solver that can be used in analysis of planar mechanisms with elastic components which achieve motion utilizing deformation of elastic members. New simulation tools are necessary to better understand the compliant mechanisms and to increase their usage in daily life. This framework was developed to fill this gap in planar mechanism design and analysis. The framework was written in MATLAB and is capable of kinematic and static analysis of planar mechanisms with compliant joints or links. Detailed information on implementation of the code is presented and is followed by the capabilities of the framework. Finally, the simulation results were compared with the Adams software to test the validity of the framework.

Forward Kinematic simulation of a 6 DOF surgical robot tracking a path through the constraint of the Remote Center of Motion point (RCM) is developed in this paper. Theoretical calculations of the forward kinematics are analyzed by solving the configuration kinematic equations of the robot. CAD prototype of the surgical robot and the patient are created using CATIA5 part and assembly tools. The theoretical results are validated through a Kinematic simulation of CATIA kinematics. The simulation results confirm the usefulness of the six revolute joint robots in minimally invasive surgery (MIS) and the efficiency of using the power full CATIA5 software to simulate surgical robot, and checking the robot mechanism capability of doing surgical procedures.
