Intelligent experimental bench for driver performance test

Abstract

The invention belongs to the technology for testing the performances of intelligent materials and relates to a research on the performance testing method of an intelligent driver. The performance test-bed of the intelligent driver mainly consists of three systems of a skeleton system (comprising a pedestal, a left guide rail, a right guide rail, the bottom board of a displacement sensor, the bottom board of a screw rod, etc), a force application system ( comprising a handle, a trapezium screw rod seat, a trapezium screw rod, a ball joint boot, the bottom board of a ball joint seat, a piezoelectric force actuator, a force measuring bridge, the bottom board of the bridge, a linear bearing, a buttery spring seat, a battery spring, a spoke type force sensor, etc) and a micro-displacement testing system (comprising a displacement sensor sleeve, a displacement sensor sleeve cover, a displacement sensor, etc); wherein, the skeleton system is the basic supporting part of the test-bed and is used for supporting the force application system, the micro-displacement testing system and the tested intelligent driver; the force application system can apply various forces for the detected force intelligent driver for detecting the load characteristics of the tested intelligent driver; the micro-displacement testing system is used for testing the output displacement (under a free state or a load state) of the tested intelligent driver. As the intelligent driver (mainly including a piezoelectric ceramics driver, a giant magnetostriction driver, a shape memorizing alloy, etc) has small displacement, high precision and high frequency response, the common test-bed can not meet the demands for the performance testing of the intelligent driver, the test-bed for performance testing of the intelligent driver is developed so as to meet the demands for the performance testing of various intelligent drivers.

Description

technical field [0001] The invention belongs to the intelligent material performance test technology, and relates to the research on the test method for the performance of an intelligent drive. Background technique [0002] Smart materials are a new class of composite materials that developed rapidly in the 1990s. There is no uniform definition of smart materials yet, however, the existing definitions of smart materials are still similar. Generally speaking, smart materials refer to materials with intelligent characteristics of perceiving environmental (including internal and external environment) stimuli, analyzing, processing, and judging them, and taking certain measures to respond appropriately. Smart materials and smart structures have huge potential application prospects, and their development will promote and drive technological progress in many aspects. Specifically, smart materials need to have the following connotations: (1) have a sensory function, be able to de...

Problems solved by technology

However, the actuators based on these smart materials, such as piezoelectric ceramic actuators, have output displacements at the micron level, and are high-precision and high-response. To study their characteristics, general experimental benches cannot meet the requirements; To make good use of these intelligent drivers, it is necessary to clarify their characteristics (displacement characteristics, load characteristics, frequency response characteristics), so a performance test bench for micro-displacement intelligent drivers is needed to test their characteristics. At present, domestic and foreign There is no test bench of this type; for this purpose, we have developed a smart drive performance test bench
