对一种新型非断裂式膨胀管分离装置进行了静力承载及分离冲击动响应分析。根据静力承载分析,获得了其啮合齿倾角与承压能力间的关系,结果显示,当接触面摩擦系数恒定时,非断裂式膨胀管分离装置的承压能力与啮合齿倾角大小呈反比,且可靠承压的临界啮合角为啮合齿自锁角。同时,根据动力响应分析,获得了非断裂式膨胀管分离装置在不同啮合齿倾角情况下的分离冲击响应,并与常规膨胀管分离装置的分离冲击响应进行了对比,结果显示,所分析的两种具有不同啮合齿倾角的非断裂式膨胀管分离装置具有比常规膨胀管分离装置更小的可靠分离内压,并且5.7°啮合齿倾角构型在相同测点处的三向加速度时程曲线峰值均低于常规膨胀管分离装置。
A new type of non-rupture expansion pipe separation device was subjected to static load and separation impact dynamic response analysis. According to the static load bearing analysis, the relationship between the inclination angle and the bearing capacity of the meshing teeth was obtained. The results show that the bearing capacity of the non-breaking expansion tube is inversely proportional to the inclination angle of the meshing teeth when the friction coefficient of the contact surface is constant. And the critical angle of reliable pressure engagement meshing teeth self-locking angle. At the same time, according to the dynamic response analysis, the separation shock response of the non-fractured expansion pipe separation device with different teeth inclination is obtained and compared with the separation shock response of the conventional expansion pipe separation device. The results show that the two Non-rupturable expansion tube separation devices with different meshing tooth inclination have a smaller reliable internal pressure separation than conventional expansion tube separation devices and the three-way acceleration time history peak at the same measurement point of the 5.7 ° meshing tooth inclination configuration Lower than the conventional expansion tube separation device.
