Abstract [eng] Recent advancements in the field of transport industry correspond to the research and development of mobility subsystems. In the suspension subsystem, the recent development and research is revolving around the active and semi-active suspension systems. Electrorheological and magnetorheological and electric and magnetic suspensions are in constant research for development. A complete literature review was carried out to determine the current research areas and scope in this field of transport development to serve the market needs. Conventional magnetorheological fluid damper (MR Fluid damper/ MRF damper) has some disadvantages such as fluid particle separation, oxidation of particles, clumping effect, hard cake formation, and behavioral stability of the fluid. In this research, an altered composition of the MR fluid to overcome the challenges faced with the conventional magnetorheological suspensions. The nano particles of nickel-iron oxide were prepared in the laboratory and based on the composition proposed the nano fluid was prepared. Synthesized nano particles were analyzed by scanning electron microscope. Rheological properties of the fluid were assessed by rheometer testing. The performance of the MR fluid in the damper setup was experimentally evaluated by quarter-car model setup and LABVIEW Signal Express software to dynamically stimulate the damper with virtual road vibrations to determine its capacity while being employed in transport. Vibrational damping efficiency of each sample for different input voltages and frequency of vibrations were determined to evaluate the optimum conditions. Market potential of the new MR fluid damper as a commercial product was analyzed by business analytical tools. The product is considered an OEM damper and the further business analytics part is carried out considering a small-scale OEM damper manufacturing industry to serve the transport industry to enhance the mobility features of a vehicle. A facility layout plan for the manufacturing industry was designed, based on which functioning and cost of the functioning were estimated. Based on the evaluated conditions, the breakeven quantity and year were determined. Prediction of sales and market growth of the sales was performed by implementing the Bass diffusion model of business. The predicted inclination period of the sales and the declension period of the sales are predicted using the Bass diffusion model for business.
