Description

一种补偿式弹簧载荷机构及其算法
技术领域
本发明涉及载荷机构应用技术领域,尤其是涉及一种补偿式弹簧载荷机构及其算法。
背景技术
在飞行员控制装置中不可缺少载荷机构,在部分机型中会采用双梯度载荷机构。但传统的双梯度载荷机构通常会存在以下特点:
A,占用空间较大,不利于减小产品体积,主要表现在长度方向上的浪费;
B,传统的载荷机构都有一个很明确的轴,补偿式弹簧机构将轴的概念模糊了;
C,传统的载荷机构在两个梯度的过度位置容易出现台阶,过度不圆滑,且不容易调节。
在某型机载荷机构的研制过程中,刚开始采用了传统的载荷机构方案
但传统载荷机构存在以下特点:长度方向上较长。
在双梯度载荷机构中,在拐点的位置通常会出现瞬变或第三梯度情况;不适于推广使用。
发明内容
针对上述现有技术存在的不足,本发明的目的是提供一种补偿式弹簧载荷机构及其算法,进而弥补现有技术的不足。
为了实现上述目的,本发明所采用的技术方案是:
一种补偿式弹簧载荷机构及其算法,机构包括第一弹簧、第二弹簧、筒部件、第一滑动套和第二滑动套;所述第一滑动套和第二滑动套套设在筒部件中部左端和右端;所述第一弹簧和第二弹簧分别设置在第一滑动套和第二滑动套外端。
一种补偿式弹簧载荷机构及其算法,其算法包括以下步骤:步骤一,用最小二乘法对拉伸过程中的点进行线性拟合:步骤二,用最小二乘法对16-30的点进行线性拟合;步骤三,用最小二乘法对回程过程中的0-16mm的点进行线性拟合;
其中,在步骤一中,令拟合直线的方程为F=kx+f;
假设位移为n时的数据记为(xn,Fn),对0-16mm的数据进行线性拟合,则可求出:k=22.02;f=47.81;
在步骤二中,用最小二乘法对16-30的点进行线性拟合:则可求出:k=6.37;
在步骤三中,用最小二乘法对回程过程中的0-16mm的点进行线性拟合:
则可求出:k=21.37;f=45.7用最小二乘法对16-30的点进行线性拟合:
则可求出:k=6.30。
进一步,所述第一弹簧和第二弹簧组成能实现双梯度的组合弹簧结构。
采用上述技术方案后,本发明和现有技术相比所具有的优点是:本发明通过实验验证,本方案的原理是可行的;有效的解决了长度方向上的空间浪费;整体设计结构简单新颖,实用性强,易于推广使用。
