Abstract: The durability and reliability of electromechanical drives is inseparably linked to the broadly defined environmental conditions under which they operate. The design of new solutions characterised by a high level of safety requires the execution of laboratory tests in accordance with the applicable legal regulations, and with a particular focus on the user requirements, that would simulate the actual environment of application. The aim of the research was to develop a test system for electromechanical drives that can be used in particularly demanding systems, e.g. fire protection or process control systems. The hardware and software solutions applied allow one to determine the characteristics (force, displacement, current, and supply voltage as a function of time) in changeable climatic conditions. As part of the verification of the system, the author studied the prototypes of electromechanical ball-screw actuators developed at the Institute for Sustainable Technologies – National Research Institute (ITeE-PIB) and dedicated for the rail traffic control system.

Abstract: In order to solve the problem of hardship and complexity in manual vehicle gateway tests, an Automatic CAN Gateway Test System was developed. The test system integrated IPC, CAN tools and network control module. It supports 2-4 channels gateways, and it also supports complex gateways with signal routing, network status management and other complicated functions. When the test is executed, the text system can simulate all the nodes which are required for DUT in normal communication to construct realistic bus environment. It can also construct relevant message status, signal status and network status to execute tests. The system, which is highly automatic, improves the accuracy and efficiency of CAN gateway test.

Abstract: We propose a test system which is easy to operate, and has high degree of automation, and introduce its detail of operating principle and test methods, and according to the requirements of the hydraulic jumbler performance, mainly test the rotational speed, flow, torque and propulsion and other performances of the hydraulic bolt rig. The measured results were analyzed and studied, and then the measures for improvement were proposed.

Abstract: As a key part feature of the machine, machine tool spindle has the characteristics of high reliability and high precision. The traditional test methods used to short the test cycle and analyze failure life of small sample data are inappropriate. Firstly, the reliability testing system of machine tool spindle was expounded; then, research status and the statistical analysis method of the performance degradation analysis used in the reliability test of machine tool spindle system were expounded. The influence to the credibility of the reliability test for machine tool spindle was put forward and analyzed: stress selection, feature selection, failure threshold selection and small sample analysis. Accelerated degradation test was given for further research in the reliability test for machine tool spindle.

Abstract: This paper presented the scenario of the IDCTMV Human-Machine Ergonomics test system with the programming idea of the modularization. Based on LabVIEW, the IDCTMV simulated test software and subjective evaluation software were designed and developed. The subjective evaluation results and operation performance data including the reaction time of crews, the rate of errors, and the rate of over reports were tested by the simulation of the integrated display and control terminal for the typical operation procedure, which solved the problems of lacking test methods for the study of the IDCTMV Human-Machine Ergonomics.
