Investigation into the Utility of the MSC ADAMS Dynamic Software for SimulatingRobots and Mechanisms
A Slider-Crank mechanism, a 4-bar mechanism, a 2R planar serial robot and a Stewart-Gough parallel manipulator are modeled and simulated in MSC ADAMS/View. Forward dynamics simulation is done on the Stewart-Gough parallel manipulator; Inverse dynamics simulation is done on Slider-Crank mechanism, …

Two-stroke linear engine
Linear, crankless, internal combustion engines may find application in the generation of electrical power without the need to convert linear to rotary motion. The elimination of the connecting rod and crankshaft can improve the efficiency of the engine significantly and the reduced weight and cost …

A drifter-based self-powered piezoelectric sensor for ocean wave measurements
… dynamic model and the FEA simulation. A slider-crank mechanism is used to mimic ocean waves throughout the experiment, and the results show a close match between the proposed dynamic modeling, FEA simulations, and experimental testing. In the end, a short discussion is devoted to interpreting …

Mechanical development of the actuation system of a parabolic solar trough
… of them, the final design chosen was a slider crank mechanism that rotates the trough about its focus. This mechanism uses a lead screw to drive the base of two passively extensible arms in a lateral direction and translates that force into a rotational motion. Whichever arm is in compression …

Steady state vibration analysis of cam driven elastic slider crank linkage with displacement parameter variation
… methods deal with the tuning of one particular mechanism. For a cam driven linkage that most often means the adjustment of the cam profile. However, these methods deal with fixed displacement parameters, parameters which were fixed once before in the design process without knowing their …

Motor simulation and parameter identification in a reciprocating mechanism
In this study, a slider-crank mechanism driven by an induction motor was studied for the purpose of deriving simulation data for the identification of the important operating parameters in the machine. First, a modification of a motor simulation program emphasizing losses is presented. The program …

Fault diagnosis and prediction in reciprocating air compressors by quantifying operating parameters
… to describe the physical behavior of the slider-crank mechanism and the shaft system. Solution techniques, which are based on the machine construction, crankshaft dynamics, and load torque measurements, are presented to determine the machine parameters. A personal computer based system used to …

Direct Sensitivity Analysis of Spatial Multibody Systems with Joint Friction
… study has been conducted on a spatial slider-crank mechanism to illustrate the application of this methodology to real-world systems. The Brown and McPhee friction model has been implemented using an index-1 formulation for computation of the dynamics and sensitivities in this case study. The …

Hybrid machine modelling and control.
… in machines can be conceived in terms of linkage mechanisms or cams which transform the notionally uniform motion of a motor. Alternatively the non-uniform motion can be generated directly by a servo~motor under computer control. The advantage of linkage mechanisms and cams is that they are …
