“…The variables about the nut following except the variables indicated specially in this section are in the frame L L L L O X Y Z . The mechanics of a lead screw is similar to two other simple machines, namely, the inclined plane and the wedge [15]. As shown in Fig.5, the lead screw is considered as an inclined plane.…”

The method based on the dynamic model to calculate the generalized interactive force between the user's head and the 6URHS parallel manipulator is proposed to validate the feasibility of the active compliance control strategy in [2]. Firstly, the dynamics pertaining to arbitrary leg of the 6URHS parallel manipulator are investigated, and dynamic equations for the leg are derived. Secondly, the dynamic analysis for the sensor group which is a part of the leg and made up of a sensor and the upper part of the spherical joint is developed, and Newton equations for the sensor group are also presented. Thirdly, the relationship expressions about the driving torques of the 6URHS parallel manipulator and the sensor feedbacks are obtained by means of combining the dynamic equations for the legs with the sensor groups. Finally, based on the dynamic model of the 6URHS parallel manipulator and the relationship expressions above, the formula for calculating generalized interactive force is proposed; both simulation and experiment are implemented, simulation results show that the feasibility and the accuracy of the proposed method are better, and the practicability of the method and the performance of the active compliance control strategy are proved to be fine with the experimental results.

Multi-degree of freedom robust control of the CNC X-Y table PMSM-based feed-drive module The paper presents results of studies on linear synchronous motors controlled in CNC feed axes through an intelligent digital servodrive. The research includes a conceptual design of an open servodrive control system and identification of dynamic models of a test stand with an open CNC system. Advantages of robust control over the classic one are discussed. A hybrid predictive approach to robust control of milling machine X-Y table velocity is proposed and results of simulation tests are presented. was prepared during the work for the Ministry of Science and Higher Education grant number N N502 336936, (acronym for this project is M.A.R.I.N.E. multivariable hybrid ModulAR motIon coNtrollEr), while its main purpose is the development of new robust position/velocity model-based control system, as well as to introduce the measurement of the actual state into the switching algorithm between the locally synthesized controllers. Such switching increases the overall robustness of the machine tool feed-drive module. The paper is the extended version of material proposed in [10].

“…This function is, according to literature [16][17][18][19][20][21][22][23][24][25][26], most notably responsible for friction dynamics. The definition of the Stribeck curve can be an arbitrary function of sliding velocity for better fitting of measured tribological characteristics.…”

“…On the other hand, the most complex friction model, the Leuven friction model [14], considers the friction coefficient as a function of sliding velocity, normal force, time, sliding direction -hysteresis effect, etc. Since friction is a high nonlinear dynamic effect and was studied by many authors [16][17][18][19][20][21][22][23][24][25][26], the capabilities of each friction model to render friction dynamics depend on how each model considers the friction coefficient.…”

This paper deals with the development and validation of a mathematical friction model for numerical friction clutch simulation within a dynamic multi-body system of complete vehicle powertrains to be used by the commercial numerical code AVL EXCITE. The corresponding requirements and demands of the automotive industry and the given software environment are presented along with the advantages of the new friction model. The focus is to find a model capable rendering important friction dynamics and true stick. Detailed tribological analysis of the developed friction model is done and results for the so called STICK/SLIP test are given, to show the capabilities and properties of the friction model. Validation of the developed friction model on a special test bed is presented. A comparison of experimental validation measurement results and numerical simulation results shows a remarkably good agreement.
