Motor Load Testing Platform And Experimental Research

The main objective of this project is the completion of a way to deal with multiple operating range, a variety of work, design and experimental study with a certain precision motor load testing platform mechanical system, it is possible to achieve high production efficiency and output external characteristics and other key technical parameters more accurate tests provide research support.Output external characteristics and other technical parameters of the motor is to evaluate the overall performance of important indicators. Motor processing, after assembly, the need to carry out the relevant tests of its key technical parameters to evaluate its performance meets the technical requirements. Therefore, the need to create a new system designed to measure the mechanical load simulation equipment more work outside the range of the motor output characteristics and other technical parameters, and selects the appropriate range of motor experimental verification. In this paper, the research work to be carried out as follows:1) The overall layout scheme:the overall layout complete selection of standard parts of each unit. When the output of the external characteristics of the test, according to the measured motor operating range and accuracy of different tests were set up four test stations can be time-sharing or simultaneously to four different motor load test to detect whether a particular case meets application requirements.2) machinery and control system detailed design:according to design requirements and has selected standard conditions, complete mechanical parts stent system, shafting and platform support detailed design, including material selection, design and manufacturing requirements for size. This article requires the loading hysteresis brake friction and reduce the impact of the moment of inertia, and reduce the impact of flexible coupling connection between shaft concentricity, double flanged rail connections and interfaces to meet different sizes of motor testing, completion of the above selection of standard parts. Use AutoCAD software to draw a two-dimensional mechanical system assembly drawing; use SolidWorks software to carry out three-dimensional modeling of mechanical systems.3) Expand the theoretical analysis is complete stress check key parts:Theory shaft between key components calculated the test platform which have a certain strength and stiffness to meet the testing requirements.4) measurement accuracy validation test:use a motor using four different ranges under the background conditions as the test piece was carried out to test the output of the external characteristics of the test, the research performance of the system meets the technical requirements.
