A computer program for design and analysis of vehicle suspension systems based on kinematic design sensitivity is devcloped. Suspension systems are modeled using composite joints to reduce the number of the constraint cquations. By directly differentiating the equations with respect to generalized coordinates and design variables, sensitivity equations are obtained. Symbolic computation technique is adopted to compute derivatives with respect to design variables. This program is to be run on Windows95 and used GUI(Graphic user Interface)for easy optimal design using sensitivity analysis.<br/>

The global mining market is building autonomous, unmanned, eco-friendly mining sites (zero-entry mining) to increase productivity, reduce costs, strengthen safety, and improve environmental burden. Although global top teer companies have entered the "Mixed-mode autonomous operation", Korean companies are in the stage of entering or proceeding with the "Lunch of autonomous mining programs". The world mining equipment is active in the technology development of eco-friendly autonomous technology and smart mining system that converge ICT technology, big data, AI, and IoT in order to build an unmanned eco-friendly mining site. In this case study, technological innovation of eco-friendly autonomous technology and smart mining system were studied. As a result of the case study, the development and the demonstration of smart mining machinery based on eco-friendly power sources (electricity/battery, hydrogen)”, the development of a smart mining platform in cooperation with industry-university-research institutes, and active M&A is necessary.
