Abstract


Compound pendulum jaw crusher is a more commonly used jaw crusher is mainly responsible for metallurgy , mining, chemicals, building materials and other industries and transportation construction stone crushing task is widely used in engineering . However, at present there is a basic structure size is too large, crushing efficiency is not high, badly worn , vibration, highlighting issues such as improving the existing jaw crusher technical level of significance . Finite element analysis as a mechanical design and manufacture a trend , it aims to analyze the stress mechanism components , checking strength, stiffness , while ensuring the safety factor in the case , the maximum for the agency to make optimized to improve machine performance. Compound pendulum jaw crusher optimization of finite element modeling software Solidworks full advantage of three-dimensional modeling and simulation platform based COSMOSWorks with COSMOSMotion , load transfer through exercise conducted kinematic and structural finite element collaborative computing , optimization of the movable jaw structure . Main contents are as follows: ( a ) in Solidworks platform for jaw crusher for three-dimensional modeling and motion simulation . Through kinematic analysis , quantitative description of the trajectory of mobile jaw crusher , horizontal and vertical travel and characteristic values, etc. , have been jaw crusher law of motion to determine the machine work cycle point of maximum load conditions . ( 2 ) Based on COSMOSMotion and COSMOSWorks simulation platform, load transfer through the movement , kinematics and structural finite element collaborative computing . The results show that the size of the movable jaw stress varies with changes in the working position . Proposed moving jaw at maximum load operating point structure stress distribution , product design and improved guidance was provided. ( 3 ) on a volume in COSMOSWorks minimum goal to stress conditions and the safety factor conditions are boundary conditions on the moving jaw structure optimization . In the thick part of the structure is more thinning to reduce aircraft weight, in order to improve economic efficiency. The study on improving the overall performance provides a theoretical basis . By moving jaw ( moving parts ) the structure and size optimization, energy saving jaw crusher better guidance.
