1 前言振动平板夯的隔振效果好坏,直接影响操作者的舒适性和工作效率,甚至影响操作者的健康与安全。为清除或降低振动对人体的危害,振动平板夯广泛采用二级减振(即夯板与机座之间为一级减振;机座与扶手之间为二级减振)。本文以我院研制的HZR-90型振动平板夯为例,介绍其隔振性能。 1 Introduction Vibration isolation plate vibration effect is good or bad, directly affect the operator’s comfort and work efficiency, and even affect the operator’s health and safety. In order to eliminate or reduce the harm of vibration on the human body, the vibration plate is widely used two-stage vibration reduction (that is, a level of vibration between the jaw and the base; two vibrations between the base and the arm). This article takes the HZR-90 vibrating plate compactor developed by our institute as an example to introduce its vibration isolation performance.
