The mechanical analysis for the platform of down-the-hole drill sustained by one outrigger
摘要
Abstract
When the sustained platform of down‐the‐hole drill was designed ,the working condition was simply considered and it was overlooked that wrong manipulation led to ultimate condition . In order to research the dangerous section of the platform under different working conditions ,the platform of down‐the‐hole drill sustained by one outrigger was analyzed minutely in mechanism and normal and ultimate conditions w ere defined .A mechanical model w as established based on theory of mechanical balance and deformation compatibility condition .The platform was analyzed in statics by using software ANSYS .The maximum stress value ,the maximum deformation value and part stress concentration area of the platform under each condition were revealed .The results indicated that the maximum stress value and the maximum deformation value under ultimate con‐dition were higher than normal condition .Besides ,the most part of the platform was in low‐stress condition and could find out excessive areas in strength and it met the demand of design un‐der condition .It provides reference for the optimization and improving of the platform structure .关键词
