A new piezoelectric inchworm actuator based on the principle of flexible amplification is developed in this paper. In the moving mechanism of the actuator, its clamping mechanism adopts symmetrical lever amplification structure, and its middle drive mechanism uses compound bridge structure. Theoretical analysis and finite element analysis are carried out to design the hinge structure which has influences on the properties of the moving mechanism. High precision cross roller guide ways are utilized to improve the positioning accuracy of the actuator. The laboratory platform of the piezoelectric inchworm actuator is built. A controlling program of the actuator is compiled by Lab-VIEW. Then, the properties of the actuator are tested. The experimental results show that the working stroke of the actuator is 50 mm, the minimum step pitch is 60 μm the maximum step pitch is 105 μm the fast speed is 2.04 mm/s, the maximum clamping force is 21 N, the maximum dead load is 500 g, and the average speed of the actuator can reach 1.47 mm/s when the driving frequency is 50 Hz and the load is 1 kg.","PeriodicalId":120368,"journal":{"name":"2013 International Conference on Manipulation, Manufacturing and Measurement on the Nanoscale","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126527456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of mechanical stretching on the rheology and deposition behaviors of EDW jet were investigated. The stretching affects that stemmed from the EDW motion platform provided an extra force on the charged jet. The larger stretching force applied on the jet played a good role to overcome bending instability, and stretch the jet into finer ones. Since the short distance between spinneret and collector, the mechanical stretching force acted more important role on the jet formation process. Thanks to the stretching effect, the whipping of charged jet can be avoided and micro/nano thin film without curve structure can be direct-written on the collector. With increasing collector motion velocity, the line width and thickness of micro/nano thin film will be decreased.

A linear sine swept signal over a range from 1 Hz to 1000 Hz is applied to the system as an input. Laser interferometry-based sensing and measurement technique is used to measure the response of the system. The experimental data is used to evaluate the transfer function of the system in the X and Y axes. The first natural frequency of the 2-DOF mechanism in the X and Y axes are estimated using the identified models, which are found out to be 557 Hz and 545 Hz respectively. Validation data is collected and used to verify the accuracy of the identified model. The error between the predicted output of the identified model and the experimental response is found to be less than ±10%, mostly resulted from actuator hysteresis.
