基于虚拟样机技术的颚式破碎机仿真优化设计

国外从上世纪中后期开始利用计算机仿真优化技术对颚式破碎机机构、腔型、产量及磨损等等进行仿真优化分析，并研制开发出无塞点、低高度、重量轻、破碎产品粒型好、产量高的高性能的新型颚式破辟机，从而大大提高破碎机性能，缩短产品开发周期，提高产品竞争力。然而我国破碎机械的设计手段落后，产品笨重，工作性能差，衬板磨损严重，操作不方便，与国外同类产品相比还有相当差距。为缩短与国外同类产品的差距，本文基于先进虚拟样机技术对新型复摆期式破碎机机构设计进行仿真优化，其主要任务是优化破碎机给、排料口水平及垂直行程，行程特性系数，从而提高破碎机处理量，减小破碎机重量，增强破碎机结构强度，减小破碎机衬板磨损，从而大大提高破碎机工作性能，缩短与国外先进频式破碎机的差距。
