一种低温下压电叠堆保温结构研究
A Warming Structure for Piezoelectric Stack Working in Cryogenic Temperature
摘要
Abstract
It is widely acknowledged that the performance of a piezoelectric stack would decline with the temperature decreasing,which will exert negative influence on its application in low-temperature environment. Therefore,a convenient and efficient warming structure for the piezoelectric stack is proposed in this paper to solve this problem. Based on the theoretical analysis of heat transfer,two heating modes,namely,overall heating and local heating are analyzed and compared. Moreover,experimental tests are conducted to evaluate the effectiveness of the structure. Based on the results,it can be concluded that the theoretical results are confirmed with experimental results. Besides, the temperature and performance of the piezoelectric stack are kept stable as temperature varies from 10 ℃ to -70 ℃, which manifests the feasibility of the structure. Therefore,this paper could be an available reference for those engaged in cryogenic investigation of smart materials and structures.关键词
