VIBRATION MEASUREMENT

Measuring vibration using vibration transducers is used across many
research and industry applications to assess how structures and machines
operate and react to stress, shock, acceleration and other parameters.

测量振动：完整指南

随着隔振和减振技术已成为机械设计的组成部分，对机械振动的精确测量和分析的需求也在增长。使用加速度计将振动运动转换成电信号，通过现代电子的多功能能力来干练地执行测量和分析过程。

Structural Testing: Mechanical Mobility Measurements

Structural testing part two deals with mechanical mobility measurements are an important stage of the engineering design process for dynamic mechanical structures. Determination of the dynamic characteristics of structures, including noise and vibration, can be used to improve and optimize the structural performance.

Modal Analysis and Simulation: Structural Testing - Part II

Modal analysis of the data obtained from structural testing, provides us with a definitive description of the response of a structure, which can be evaluated against design specifications. It also enables us to construct a powerful tool, the modal model, with which we can investigate the effects of structural modifications or predict how the structure will perform under changed operating conditions.

Measuring Vibration Characteristics in Seating

A long commute is often stressful and tiring, so comfortable seating becomes increasingly important for drivers as well as passengers. But how do we test the overall comfort quality of seats?

Niels-Jørgen的五个问题

Niels-Jørgen Jacobsen出生于丹麦的博恩霍尔姆岛，是Brüel & Kjær的结构动力学产品经理。这位歌剧家瓦格纳的狂热粉丝还自认为是个美食家，梦想开一家自己的酿酒厂。他还跑马拉松，相信身体健康是美好生活的代名词。

Japanese Professor of Human Vibration

When a typhoon wreaked havoc during his formative years, Dr Setsuo Maeda altered the course of his career, resolving to help Japanese workers in the clean-up effort by reducing their vibration injuries. He went on to spearhead Japan’s adoption of ISO standardisation in the area, and now teaches a sought-after course that prepares Japanese students for the globalised world.We caught up with Dr Setsuo Maeda in his office at Kinki University, 560 km west of Tokyo in Osaka Prefecture. Surrounded by shelves of...
