Based on ANSYS large diameter metallic high-speed rotating disk modal analysis KONG Fanliang1, a，HE Tao1, b，HANG Lubin1, c ，REN Xiaoqing1, d 1 Address: Shanghai University of Engineering Science, China, 201620 a email: kfl1989@126.com, bemail: hetao_cn@126.com c email:hanglb@126.com, d email:renxiaoqing_cn@126.com Keywords: ANSYS; high speed disc; modal analysis; natural frequency; inherent vibration Abstract: The modal analyses for rotating disk with pre-stressed in different high speeds were made respectively based on the finite element software of ANSYS.
During the disc rotating at high speed, its large diameter, instable material and other factors, it tend to produce large-vibration, big noise, and even direct fracture, which leads to decreased reliability of the disc's work and bring unnecessary losses for company.Therefore, in order to ensure its stable and reliable structure, reducing vibration and noise, in addition to the structure on the disc stiffness strength design, it's absolutely necessary to analyze the disc's vibration modal.
