This paper reviews the situations and features of earthquake damage to industrial facilities, manufacturing companies, energy supply facilities, and mechanical structures and installations in Japan, and traces trends of countermeasure technology developed focusing on earthquake resistance and vibration control. In Japan, with the 1964 Niigata earthquake as the turning point, earthquake damage to industrial facilities became a social problem. With power stations being constructed in the 1960s, it also became an important technological policy to establish seismic design method for nonbuilding structures such as equipment and piping systems related to nuclear power. The Kobe earthquake in 1995 damaged production companies including leading manufacturers so extensively that it brought a new focus to seismic considerations. We studied the damage to typical equipment and installations and, based on this experience, investigated the features of damage modes to industrial facilities and machinery and considered corresponding technical measures. We present some examples and discuss progressive trends in seismic and vibration control technology following the Kobe earthquake. In particular, we focus on the new seismic design code for high-pressure gas facilities and the development of seismic and vibration control dampers and their applications.

A review of research on the vibration control technology inspiration from the biological vibration damping mechanisms is described. First the important concept and background of the bionic vibration damping technology are briefly introduced. Then the basic theories and its applications in the engineering fields are elaborated from three aspects: vibration damping mechanisms of the creatures own the good ability to withstand the ambient vibrations, mechanical models of biological prototypes and its application progress in the practical occasions.

AbstractElectro-hydraulic vibration equipment (EHVE) is widely used in vibration environment simulation tests, such as vehicles, weapons, ships, aerospace, nuclear industries and seismic waves replication, etc., due to its large output power, displacement and thrust, as well as good workload adaptation and multi-controllable parameters. Based on the domestic and overseas development of high-frequency EHVE, dividing them into servo-valve controlled vibration equipment and rotary-valve controlled vibration equipment. The research status and progress of high-frequency electro-hydraulic vibration control technology (EHVCT) are discussed, from the perspective of vibration waveform control and vibration controller. The problems of current electro-hydraulic vibration system bandwidth and waveform distortion control, stability control, offset control and complex vibration waveform generation in high-frequency vibration conditions are pointed out. Combining the existing rotary-valve controlled high-frequency electro-hydraulic vibration method, a new twin-valve independently controlled high-frequency electro-hydraulic vibration method is proposed to break through the limitations of current electro-hydraulic vibration technology in terms of system frequency bandwidth and waveform distortion. The new method can realize independent adjustment and control of vibration waveform frequency, amplitude and offset under high-frequency vibration conditions, and provide a new idea for accurate simulation of high-frequency vibration waveform.
