摘　　要：从双曲柄滑块机构的一般位置即偏转型出发,建立了综合因素影响下的V7表达式,用解析法和计算机编程计算分析了机构的4种位置时的运动平稳性.结果表明,双曲柄滑块机构滑块的运动平稳性较好.在原动件θ1约200°的转角范围内,速度没有波动.而且偏转角α在其可行域内,V7的性状基本不变.在上偏转式机构中,α一定程度地影响机构的平稳性;而在下偏转式机构中不影响平稳性.对心式和上、下偏置式双曲柄滑块机构在各构件尺寸一定时,通过选择合适的安装角β,可获得良好的运动特性和平稳性.In this context,based on deflection type of slider-double-crank mechanism,V7 expression formula under the influence of multiple factors is established.Then motion stability of four positions are analysed by analysis method and computer programming calculation.The results indicate that slider-double-crank mechanism has exelent motion stability.The speed doesn＇t change among the range 200° angle of driving link θ1.And character of V7 doesn＇t change in avalible area of deflection angle α.Deflection angle α influences the stability of mechanism in certain extent in up bias mechanism,but not do it in down bias mechanism.It could show good character of motion and stability of center,up bias and down bias mechanism at certain size of each link when proper mounting angle β is chosen.
