Research on rapid-charge type Ni-MH battery for electric tools application;

The esthetics characters of electric tools sculpting and human esthetics taste were combined by fuzzy theory to comprehensively evaluate electric tools sculpting.

Based on relevant theory of modular design,the paper studied modular design process of electric tools,particularly on three aspects such as module partition,modular establishment and developing of module management system based on UG.

Based on the study of implement mechanism of electric reciprocating saw,a kinematic and dynamic model was established,the picture of electric tool′s motion framework with reciprocating lever inextenso were made and the situation and design method of the motion framework which mentioned above were analysed,also the balance framework was improved by using ADAMS.

<Abstrcat>This paper introduces the application of computer in electric tool automatic testing line.

In this paper, on the basis of finishing to study on the working circumstance simulation , a synthesis performance testing system to test electric tools working characteristic, temperature rising characteristic and four kinds of safety provisions was developed, in order to meet the strong need of test & measurement techniques from electric tools.

The application and development of rapid prototyping technology were reported,and development characteristic of power-driven tool was discussed.
