Technical Problem
这些曲线的凸轮轮廓经过理论与实验研究之后均证明了其与线性隔振系统的优越性，但是，其准零刚度性能却是大同小异，由于他们在一开始就给定了凸轮的方程，所以研究的隔振设备的刚度-位移曲线都是一条类似于开口向上的抛物线，如图1中黑色曲线所示，存在准零刚度区间(隔振区间)过小的问题
Benefits of technology
[0049]该凸轮曲线轮廓计算方法中的a＝0情况能使使用该计算凸轮的隔振器的系统回复力及刚度总体始终保持零/准零状态，而不是随着系统位移的变化而变化，该种特性使得使用该计算方法的凸轮型隔振器起始隔振频率近乎为零，运用此方法经过合理的设计后，理论上可以隔绝几乎所有的振动，对于生产生活中需要隔离振动的场景具有极大的有益效果。除此之外，利用本方法中令f(v)＝av，也可以计算出使系统总体刚度保持为a的凸轮轮廓，可用于其他有需要的场合。

Abstract
The application discloses a cam curve profile calculation method of a vibration isolation device, and relates to the technical field of vibration isolation. The a=0 condition in the cam curve profile calculation method can keep the system restoring force and stiffness of the vibration isolator using the calculated cam always in a zero / quasi-zero state, instead of changing with the system displacement, and the characteristic makes the initial vibration isolation frequency of the cam type vibration isolator using the calculation method be nearly zero. After reasonable design by using the method, almost all vibrations can be isolated in theory, and the method has great beneficial effects on scenes needing vibration isolation in production and life. By letting f(v)=av in the method, the cam profile making the system overall stiffness keep a can also be calculated, and can be used in other needed occasions.
