加速度计技术的巨大进展,使新的 应用在经济上变得可行,并正在 使传统的加速度计市场发生革命性的变化。压阻式加速度计的性能足以同压电式、应变仪式以及伺服加速度计相媲美,而其生产成本却低得多。 这篇文章讨论了加速度计的基本原理、设计及性能特点,此外,对不同的加速度检测技术作了比较。悬块式加速度计的原理 加速度计可被简单看作由弹簧、弹簧连接的重物和固定弹簧的框架组成,其示意图见图1。当框架移动时,重块试图保持静止,直至弹簧受拉后向它施加足够大的力使之运动。通过电子检测装
The huge advances in accelerometer technology have made new applications economically viable and are revolutionizing the traditional accelerometer market. The performance of piezoresistive accelerometers is comparable to piezoelectric, strain gauge and servo accelerometers, and their production costs are much lower. This article discusses the basic principles, design and performance characteristics of accelerometers. In addition, different acceleration detection techniques are compared. The principle of a suspension-type accelerometer Accelerometer can be simply seen as a spring, a spring-loaded weight, and a spring-loaded frame, a schematic of which is shown in Figure 1. As the frame moves, the weight tries to stay still until the spring is pulled and exerts enough force on it to move it. Through the electronic test equipment
