The invention discloses a multi-spring cam roller quasi-zero stiffness vibration isolation device, and belongs to the technical field of vibration isolation. The multi-spring cam roller quasi-zero stiffness vibration isolation device comprises a bottom plate, a loading platform and a fork type lifting mechanism, and further comprises a first sliding rod and a second sliding rod, the supporting beam is provided with a first sliding hole, the supporting beam is slidably connected to the first sliding rod through the first sliding hole in the length direction of the first sliding rod, and one end of the supporting beam is connected with the fork type lifting mechanism; the X-direction spring is used for applying elastic force opposite to the movement direction of the supporting beam to the supporting beam; a cam; when the supporting beam slides on the first sliding rod, the supporting beam drives the spring telescopic mechanism to stretch out and draw back through the cam. According to the multi-spring cam roller quasi-zero stiffness vibration isolation device, the stiffness of the whole vibration isolation device is reduced, the inherent frequency of the whole vibration isolation device is reduced, the good bearing capacity is kept, and low-frequency vibration of a transported object can be effectively isolated.
本发明公开了一种多弹簧凸轮滚轴准零刚度隔振装置,属于隔振技术领域。该多弹簧凸轮滚轴准零刚度隔振装置,包括底板、装载平台和叉式升降机构,还包括:第一滑杆;支撑梁,设有第一滑孔,支撑梁通过第一滑孔沿第一滑杆的长度方向滑动连接于第一滑杆上,支撑梁的一端与叉式升降机构连接;X向弹簧,用于向支撑梁施加与支撑梁运动方向相反的弹性力;凸轮;弹簧伸缩机构,当支撑梁在第一滑杆上滑动时,支撑梁通过凸轮驱动弹簧伸缩机构伸缩。本发明的多弹簧凸轮滚轴准零刚度隔振装置,既降低了整个隔振装置的刚度使整个隔振装置的固有频率降低,又保留了良好的承载能力,能有效隔离被运输物体的低频振动。
