Synthesizing force systems for motion time response, input-output forces and joint force control using interactive graphics and influence coefficients
"THE PRIMARY OBJECTIVES OF LINKAGE DESIGN: The four design objectives most generally encountered when designing a linkage are: Objective 1: Kinematic, a linkage is geometrically designed to meet kinematic objectives such as rigid body guidance, path generation or function generation. Objective 2: …

An experimental investigation of camshaft dynamics.
… through the camshaft bearings. Using the influence coefficients theory for a static linear system equations were developed for use in a dynamic system. A test rig was designed and built around a Ford 2.0L DOHC engine so that experimental vibration information, in the form of frequency …

Adaptive control of a four-bar linkage
… dynamic model is developed using Kinematic Influence Coefficients. This model is used to develop the adaptive controls and to computer simulate the control scheme performances. The simulated model velocity response is compared qualitatively to experimental data and shown to be similar to an …

Static and free-vibrational response of semi-circular graphite- epoxy frames with thin-walled open sections
… has a channel cross section. The flexibility influence coefficients were measured in static tests for loads applied at midspan with the ends of the specimens clamped. Natural frequencies and modes were determined from vibrational tests for free and clamped end conditions. The experimental data …

Influence of Turbofan Engine Design Parameters on Aircraft Environmental Impact
… environmental impacts are significantly influenced by the design of these turbofan engines. Hence, we should drive the design of modern turbofan engines, informed with each design parameter’s effect on environmental implications, namely the climate and air quality impacts. To understand …

An investigation of real gas effects in supercritical CO₂ compressors
… for ideal fluids, are investigated using the influence coefficients for compressible channel flow derived for real gas. The variation in the properties of CO2 and the expansion through the vapor-pressure curve due to local flow acceleration are identified as possible mechanisms for performance …

Finite element analysis of nitrogen species transport and transformation in the unsaturated zone
… triangular elements were used, the method of influence coefficients is more efficient than traditional numerical integration method in evaluating the element matrices while maintaining accuracy. Also with moderately nonlinear flow problems, use of a fourth order Runge-Kutte method produced …

On the false-diffusion problem in the numerical modelling of convection-diffusion processes
… a successful discretisation scheme, eg positive coefficients. conservation and the elimination of 'false-diffusion', a new flow-oriented finite-volume numerical scheme was devised and applied to several test cases in order to evaluate its performance. The novel approach in formulating the new …
