Vocal fold vibration mode changes due to cricothyroid and thyroarytenoid muscle interaction in a three-dimensional model of the canine larynx

Taking a large vertical machining center spindle box as research object, its three-dimensional model is established by using Pro/ENGINEER software. Due to the seamless integration between ANSYS Workbench and Pro/ENGINEER, ANSYS Workbench is used to structural analysis of static and dynamic characteristics of spindle box. It has been achieved which includes static stress, deformation, inherent frequencies and vibration mode. Based on the analysis results, improvement scheme for spindle box structure has been proposed and validated. This study provides theoretical basis for design and improvement of machining center spindle box.

Centrifugal Pendulum Vibration Absorber

This paper investigates the vibration mode structure of three-dimensional, cyclically symmetric centrifugal pendulum vibration absorber (CPVA) systems. The rotor in the system has two translational, one rotational, and two tilting degrees of freedom. The equations of motion for the three-dimensional model, including the rotor tilting, are derived to study the modes analytically and numerically. Only three mode types exist: rotational, translational-tilting, and absorber modes. The rotational and absorber modes have identical properties to those of in-plane models. Only the translational-tilting modes contain rotor tilting. The veering/crossing behavior between the eigenvalue loci is derived analytically.

The Finite Element Analysis

The connecting rod is an important part in the engine cylinder. This paper studied the engine cylinder by using Pro/E and ANSYS and achieved some interest results. It used the Pro/E to establish three-dimensional model of the engine and to simulate on it. It also analyzes the connecting rod of cylinder by using the finite element analysis software ANSYS, its modal analysis method was put forward and the low natural frequency and vibration mode were calculated. The analysis method and the results can provide reference for the dynamic design of the connecting rod, and also provide a method for the fault diagnosis engine system.
