摘要

针对单个曲柄连杆机构具有二次谐波的传动特性，创新地提出了具有输出精确正弦规律速度-时间特性的复合曲柄连杆机构。解析分析论证了新机构具有的输出特性，推导得出其速度公式；考虑在调整两个曲柄长度时存在的误差，分析了其长度差对输出误差的影响；运用Adams软件对机构进行了仿真计算，在2个曲柄长度存在0.5 mm的差异时，其速度输出规律与标准正弦曲线之间的误差较小。研究结果表明，该机构可将单个曲柄连杆机构的位移-时间和速度-时间的误差从25%降低到1%以下，能够满足潮汐能发电装置和汽车悬架振动等产品在初试时低成本和快速试验的要求。

Abstract

Aiming at the transmission characteristics of the second harmonic of a single crank connecting rod mechanism

a composite crank connecting rod mechanism with output precise sinusoidal velocity-time characteristics is innovatively proposed. The output characteristics of the new mechanism are demonstrated through analytical analysis

and its velocity formulas are deduced. Considering the error existing in adjusting the lengths of the two cranks

the influence of the length difference on the output error is analyzed. The Adams software is used to simulate the mechanism. When the difference between the lengths of the two cranks is 0.5 mm

the error between the speed output law and the standard sine curve is small. The research results show that the mechanism reduces the velocity-time errors of a single crank-link mechanism from 25% to less than 1%

which can meet the requirements of low cost in the initial test of products such as tidal energy power generation devices and automobile suspension vibrations. It also meets the requirements for rapid experimentation.
