Abstract: The structure of a 3-DOF parallel manipulator is presented. The methodologies of multiple-mode negative impulses input shaping is introduced, which can decrease the delay time of the system response while the residual vibration is suppressed. The parameters of two-mode negative impulses and positive impulses input shapers of the 3-DOF manipulator are presented. The sensitivity analysis of these input shapers are carried out through numerical simulations, and the robust of the input shapers are presented and compared.

Abstract: A lot of lubricating oil is consumed in the process of the cold rolling of stainless steel. The oil recovery is very important due to some reasons, such as the cost of production and environmental pollution. A set of lubricating oil recovery system is designed and constructed, which is equipped with a set of expanded size recovery oil pan for recycling splashed oil, a high efficiency two-level mist recovery system for recycling the oil mist, and an oil collection platform for recycling the oil rolled. The system is effectively to recovery more of lubricating oil through actual use and measurement.

Abstract: There is a set of 6 degrees of freedom (6-DOF) loading system with the simulated border for the application of material structural strength and reliability tests. This is a novel equipment for the tests of structural mechanical properties and reliability in different materials. This study showed a three-dimensional structure model, introduced the definition of the test of the 6-DOF loading system with the simulated border, and discussed the primary theory of the system and technical performance. Based on the matrix of direction cosine of the system, the solutions of inverse kinematics of 6-DOF loading system were given. The system of control was introduced as well.
