【摘要】 为解决大型三轴试验机横梁的大尺寸升降问题,提出一种新型光杠自锁升降装置,其原理是通过与立柱相联结的可涨开过盈弹性套和可锁紧开口弹性套与提升油缸的交替运动实现横梁的"无限"导程。更多还原

【Abstract】 A new-style slick pole self-lock up-down setting was designed to realize large size up-down of crossbeam,its principle is that limitless pass of the crossbeam is realized by alternate motion of overtop elastic cannula and ringent elastic cannula connected with poles.更多还原
