Exploration of deep-rock mechanics has a significant influence on the techniques of mining and rock mechanics. Rock coring technique is the basic method for all rock mechanics study. With the increase of the drilling depth and increasing strength of the hard rock, how to obtain high-quality rock core through various coring techniques is an eternal work. Here an innovative method is applied to design the new coring system to maximize the efficiency of operation. The stress conditions or parameters of rock core in the coring are analyzed, and the mechanism of the core with in situ stress is shown in this paper. The conflict of the core and coring tool chamber is proposed for the innovative design. The innovative design method is fulfilled by the theory of inventive problem solving (TRIZ). An improved coring system for the full-length core with in situ stress was obtained with the solutions of improved coring mechanism, cutting mechanism, and spiral drill pipe.

“…Existing methods on the product evolution analysis are classified as approaches of customer demands driven and technology advancements driven. 25,26 The customer demands driven approach for the product evolution analysis usually includes two steps of analyzing trends of customer demands, and mapping customer demands into a set of product specifications for new product design. Opinions from experts and/or customers are collected for the prediction of potential trends of market/customer requirements on product features.…”

Products are constantly evolving through design adaptations to satisfy market requirements. Efficient design adaptation via maximal reusing of existing design can improve product quality, reduce manufacturing cost, and time to market. Understanding of product evolution mechanism is required for design adaptations through rationalized modularity and interfaces. Emerging big sales data provide rich resources for product evolution analysis. To support efficient design adaptations, a framework and associated methods are developed in this work using big sales data for product evolution analysis. Reproduction, mutation, and crossover of product specifications are introduced as specification adaptation operations. Methods are proposed for identification of specification adaptations and estimation of the adaptation probability. Based on modeling and analyzing relationships among product specifications and components, different types of modules and interfaces are proposed through components clustering and their potential operation (mutation, reproduction, and crossover) probabilities. Design recommendations of adaptable product architecture with modules and interfaces are made for facilitating design adaptations. A case study of consumer Unmanned Aerial Vehicles (UVAs) illustrates the proposed method. Limitations and potential extensions of the newly developed method are discussed. Further investigations of the product evolution mechanism using game theory to support competitive product development are included.

“…The use of hybrid body technologies (i.e., those resulting from the combination of different materials in order to exploit their properties synergically) in machine tool load-bearing systems manufactured individually or in small batches can provide specific benefits in terms of a significant reduction in the design time, particularly in terms of the calculations needed to shape their structure and the desired static and dynamic properties [1]. It is particularly important to shape the desired resistance of the designed machine tool frame to chatter [2][3][4][5][6][7].…”

At the stage of designing a special machine tool, it is necessary to analyze many variants of structural solutions of frames and load-bearing systems and to choose the best solution in terms of dynamic properties, in particular considering its resistance to chatter. For this reason, it is preferred to adopt a low-dimensional calculation model, which allows the user to reduce the necessary calculation time while maintaining a high accuracy. The paper presents the methodology of modeling the natural frequencies, mode shapes, and receptance functions of machine tool steel welded frames filled with strongly heterogenous polymer concrete, using low-dimensional models developed by the rigid finite elements method (RigFEM). In the presented study, a RigFEM model of a simple steel beam filled with polymer concrete and a frame composed of such beams were built. Then, the dynamic properties obtained on the basis of the developed RigFEM models were compared with the experimental results and the 1D and 3D finite element models (FEM) in terms of accuracy and dimensionality. As a result of the experimental verification, the full structural compliance of the RigFEM models (for beam and frame) was obtained, which was manifested by the agreement of the mode shapes. Additionally, experimental verification showed a high accuracy of the RigFEM models, obtaining for the beam model a relative error for natural frequencies of less than 4% and on average 2.2%, and for the frame model at a level not exceeding 11% and on average 5.5%. Comparing the RigFEM and FEM models, it was found that the RigFEM models have a slightly worse accuracy, with a dimensionality significantly reduced by 95% for the beam and 99.8% for the frame.
