摘要
为研究超声振动对风扇盘组叶片装配压装力的影响,提出一种将超声振动与压装进行结合的装配方法。并利用控制变量法研究压装形式、压装位移、压装速度、振动幅值4个因素对风扇盘组相邻叶片装配压装力的影响规律。研究表明,叠加超声振动能够有效减小风扇盘组相邻叶片装配的压装力;压装位移越大,装配所需压装力越大,叠加一定振动幅值的超声振动能有效缩小不同压装位移之间的压装力差距;无论是否叠加超声振动,在一定的压装速度范围内,压装速度基本不会对压装力产生影响;在一定振动幅值范围内,随着叠加振动幅值的增加其减小压装力的效果越好,到达某一振动幅值,减小压装力的效果达到最好,可以使压装力减小75%,超过该振动幅值,减小压装力的效果趋于稳定甚至会减弱。
To study the effect of ultrasonic vibration on the assembly and pressing force of fan disk blades,an assembly method combining ultrasonic vibration and pressing is proposed.And the control variable method is used to study the influence of four factors,namely press installation form,press installation displacement,press installation speed,and vibration amplitude,on the assembly press installation force of adjacent blades of the fan disk group.Research has shown that superimposed ultrasonic vibration can effectively reduce the pressure installation force of adjacent blade assemblies in fan disk groups;The larger the pressing displacement,the greater the required pressing force for assembly.Superimposing a certain amplitude of ultrasonic vibration can effectively reduce the difference in pressing force between different pressing displacements;Regardless of whether ultrasonic vibration is superimposed or not,within a certain range of pressing speed,the pressing speed basically does not affect the pressing force;Within a certain range of vibration amplitude,as the superimposed vibration amplitude increases,the effect of reducing the pressing force becomes better.When reaching a certain vibration amplitude,the best effect of reducing the pressing force can be achieved,which can reduce the pressing force by 75%.Beyond this vibration amplitude,the effect of reducing the pressing force tends to stabilize or even weaken.
