Modified Dynamometer.
RENEWED interest in ophthalmodynamometry during recent years has revealed difficulties in the actual technique which may be attributable, at least in part, to the dynamometer in common use, designed by Bailliart (1917). Many of these troubles have their origin in the lack of control over the instrument that is so frequently experienced. This is especially common when the operator is in the earl...
متن کاملValidity of the Handheld Dynamometer Compared with an Isokinetic Dynamometer in Measuring Peak Hip Extension Strength
PURPOSE To determine whether the handheld dynamometer (HHD) is an appropriate tool to assess and quantify peak hip extension strength in prone standing position by (1) evaluating the concurrent validity of the HHD versus an isokinetic dynamometer (IKD), (2) establishing the minimal detectable change (MDC), and (3) determining the validity of single-trial versus multi-trial measures. METHOD A ...
متن کاملA pedal dynamometer for off-road bicycling.
This paper describes the design and accuracy evaluation of a dynamometric pedal, which measures the two pedal force components in the plane of the bicycle. To realize a design that could be used during actual off-road cycling, a popular clipless pedal available commercially was modified so that both the form and the function of the original design were maintained. To measure the load components...
متن کاملHigh Dynamic Engine-Dynamometer Identification and Control
In this paper, a high dynamic test-bed control problem for high dynamic vehicle simulation is studied in order to improve the tracking of speed and torque. As the system is nonlinear and square (2x2) with two inputs and two outputs, a multi-input multi-output (MIMO) system-identification problem is discussed. The test-bed data are processed using a fast frequency domain methodology to build a n...
متن کاملDetermination of inertial parameters using a dynamometer.
In this study, a simple method based on the dynamic equation of motion was introduced to determine the moment of inertia using a commercial dynamometer, and an optimization technique was utilized to estimate inertial parameters with the determined moment of inertia. To evaluate the feasibility of the developed method, three different passive speeds (i.e. 240, 270 and 300°/s) were chosen to conf...
