Abstract A methodology is presented herein for experimentally evaluating the static and elastodynamic responses of industrial robotic manipulators. The procedure enables estimates of the principal characteristics of these machines to be quantified in order to identify limitations in the structural elements of these designs. Furthermore, the proposed approach also provides experimental data with which to evaluate the predictive capabilities of the various mathematical models proposed in the literature for predicting the static and elastodynamic behavior of these systems. In order to demonstrate the test procedure, a General Electric Company P50 articulating robot was subjected to evaluation, the error sources identified and the associated errors quantified.

Good Agreement

Predictive mathematical models for the depth of jet penetration are presented for both straight-slit cutting and contouring by an abrasive waterjet (AWJ). The plausibility and predictive capability of the models are assessed and verified by an experimental investigation when cutting an 87% alumina ceramic. It shows that the predictions of the models are in good agreement with the experimental data.

Procedure Development

In 2014 for the realization of experimental investigation there was assembled a completed experimental plant for testing lowspending turbo-machines with the use of an inductor brake (IB) at the enterprise “Microturbine Techniques” Co. and was installed on a test board of the laboratory of the department “Turbines, Fluid Machines and Aviation Engines” of SPbPU. In the structure of a test bench there is included an air system, oil system, system of control, measuring and information accumulation. From the air system air passes through a flow gage and delivered to IB. All tests will be agreed with the frequencies of rotor rotation in the course of which there were carried out measurements. According to values read of consumption, pressure, temperatures and efforts to a stator lever of an inductor brake with the aid of PC software the parameters of a lowspending centrifugalflow compressor (LCC) will be computed. The criterion of capacity equality consumed by LCC and taken off from a lowspending radialaxial turbine will be zero value of the effort on a stator lever of an inductor brake. As a result of the work performed the IB equipment is prepared, all systems of the test board are connected up. The systems of control, measuring and experimental data accumulation are connected up and adjusted. A visualization program is developed.

In this work we present a soft crawler fabricated using a magneto-active elastomer. The crawler is controlled by an external magnetic field to produce two locomotion patterns: peristaltic and caterpillar crawling. Due to its structural simplicity, low mass, wirelessly controlled actuation and compliant body the design of this crawler has the potential to address the key challenges faced by existing crawling robots. Experimental data were gathered to evaluate the performance of the crawler locomotion in a pipe. The results validated the mathematical models proposed to estimate the distance traveled by the crawler. The crawler shows potential for use in exploration of confined spaces.

A method to investigate pipe wall thinning using guided waves has been developed for pipes in thermal power generation facilities. In this paper, the reflection coefficient and the transmission coefficient are derived for the torsional waves which propagate along a pipe and a simplified method to predict the waveform is proposed. The predictions of the waveforms by the FEM and a simplified method based on the reflection of torsional waves are also examined by comparing with experimental data.
