| Abstract: | Using the bottom dead center measuring apparatus,the wave-form test was made for some kinds of high-speed presses,which revealed the varying regulation of the bottom dead center when the static balancing air pressure and the crank's rotating speed varied without load.The reason causing this regulation was analyzed,the curvilinear equation was established and its significance was checked,the improving measures were also offered to enhance the precision of the bottom dead center. |
