图4 试验台循环系统示意图 摩托车仪表在使用中是直接裸露在自然环境中的。为了适应摩托车在雨天行驶的需要,摩托车仪表应具有防雨功能。为此,摩托车仪表生产厂家需按设计标准对所生产的仪表在模拟条件下进行防雨和溅水试验,以满足实际使用要求。 1 造型设计 试验台由控制室、测试室、传动供水室三部分组成。 控制室是试验台工作的核心,位于柜体最上部。其 Figure 4 test bench circulatory system diagram Motorcycle instrument in use is directly exposed in the natural environment. In order to meet the needs of motorcycle driving in the rainy day, motorcycle meter should have a rain-proof function. To this end, motorcycle meter manufacturers according to the design standards for the production of instruments under simulated conditions rain and water splash test to meet the actual use requirements. 1 modeling design test bed by the control room, test room, transmission water room composed of three parts. Control room is the core of the test bench, located in the top of the cabinet. its
