引言近年来,机械工业的发展对金属切削机床的精度及运转性能的要求不断提高,液体静压支承因其特点(滑移面无金属接触,完全液体润滑,摩擦力甚小)而获得广泛应用。对于液体静压支承,目前还是一项新技术,虽然对其静态性能已作过较多的研究试验,但对其动态性能则了解较少。对于一些采用静压支承的机械在运转中出现问题时,静压支承往往成为首先被怀疑的对象。许多单位就曾提出过:液体静压支承系统是
INTRODUCTION In recent years, the development of mechanical industry has raised the demand on the precision and running performance of metal cutting machine tools. Hydrostatic bearing has been widely used due to its characteristics (no metal contact on sliding surface, complete liquid lubrication, little friction) . Hydrostatic support is still a new technology at present. Although more studies on its static performance have been made, its dynamic performance is poorly understood. Hydrostatic support often becomes the first suspect object for some machines that use hydrostatic support in operation. Many organizations have said: hydrostatic bearing system is
