1.前言最近,日本建设省九州技术事务所对手提式碎石机安装了动力减振器及缓冲橡胶等,取得了较好的减振效果.本文作简单介绍.2.振动的检测方法振动的检测,按照“手提式动力工具的振动能量检测方法”(日本1979年9月7日某专门委员会所订)来进行.振动检测器是压电加速度型,用金属带固定在手柄中心部位(图1)上.在X、Y、Z3个方向上检测振动加速度(VAL)和振动能量(VL),但本文仅讨论在撞铁的打击方向——X方向(对于手掌上下振动方向)的情况

1. Introduction Recently, the Kyushu Technology Office of Japan’s Ministry of Construction has installed dynamic shock absorbers and cushioning rubber on hand-held stone crushing machines and achieved good damping effect. This article gives a brief introduction. 2. Vibration Detection Method Vibration According to “Vibration energy detection method of hand-held power tool” (set by a special committee in Japan on September 7, 1979) The vibration detector is of piezoelectric acceleration type and is fixed at the center of the handle Figure 1) Vibration Acceleration (VAL) and Vibrational Energy (VL) are measured in X, Y, and Z directions, but this article only discusses the case where the striking direction of the striker is in the X direction (for the up and down vibration direction of the palm)
