Study On Ergonomics Simulation Design Of Operating Platform Of Boom-type Roadheader

The structure parameters of of operating platform of boom-type roadheader have an important influence on driver's sitting posture comfort,maneuverability,wide field of vision and safe and efficient operation of fully mechanized excavation.Fully considering the coupling relationship and cross influence between the driver's physiological factors and the structure parameters of operating platform.Using typical anthropometric data model to build typical manikin of boom-type roadheader,analysis of man-machine matching degree of operating olatform of boom-type roadheader by the Newton-Raphson algorithm which is used to solve the expression of the closed loop vector equation of Two-dimensional kinematics typical manikin.Comfortable angle of the driver's upper arm manipulating reversing valve is put forward for different typical manikins.The reasonable structure parameters of operating platform are put forward.Anybody Modeling System and the CATIA simulation software are used to certified their correctness.Typical anthropometric data models are established by using the clustering algorithm based on Simulated Annealing Algorithm_Genetic Algorithm_Fuzzy Clustering Algorithm.Types: typical anthropometric data model I~typical anthropometric data model IX.From the three aspects of comfort,maneuverability and wide field of vision,comfortable angle of the driver's upper arm manipulating reversing valve is put forward for different typical manikins are analyzed.The reversing valve length of operating platform is 539 mm,the angle of the horizontal plane of the reversing valve and operating platform is 37 degrees,the seat height of typical manikin III is 360 mm,the seat height of typical manikin V is 397 mm,the seat height of typical manikin VI is 398 mm,the seat height of typical manikin VIII is 426 mm,the seat height of typical manikin IX is 420 mm.Anybody Modeling System was used to analyze the human biomechanical parameters of each typical manikins with the height of the cushion and the angle of the seat back.According to the result analysis,there are differences in biomechanical load between different typical manikins under the same seat parameters.However,the areas with smaller biomechanics load of different typical manikins are concentrated at the height of H 350mm~450mm,the angle of the seat backrest is 5 degrees and 20 degrees ~30 degrees.It is verified that the structural parameters of the improved operating platform can ensure the comfort,maneuverability and visual field of the drivers of different typical manikins by CATIA simulation software.Comprehensive driver modeling solution,AMS and CATIA simulation can effectively analyze driver's sitting posture comfort,maneuverability and wide field of vision.The rationality and universality of the structure parameters of of operating platform of boom-type roadheader can be improved and designed to the actual design.Give the correct guidance.
