Automobile crusher gauge

The paper presents a new kind of wireless dynamic parameter measurement system which records the automobile colliding process called an automobile crusher gauge (ACG). In a collision process, the ACG can be housed in any place. For example, inside the head, rib cage and the legs of the anthropomorphic dummies in order to study the automobile's structure and determine the component's response to various impact shocks. The battery for ACG is built in and the stored data in ACG can be held for more than one year. In addition, the ACG can bear impact shock as high as 10,000 g. In this paper, the ACG's composition and working principle are introduced in detail, and the test results of the ACG are also supplied.
