The Relationship of Properties and Variable Mass of Block on Crank Linkage Mechanism in Multibody System

Abstract

The multibody relationships between Parameters and angles in crank linkage is investigated in this study and found little force and big speed formed in the dynamics with Lagrange formula in the condition of 720r/m and variable mass of sliding block. When the mass is big the force may incline. The speed will attain the maximum value of 120m/s and acceleration reaches 0.1mm/s2. The torque is biggest with 300Nm on crank and then 5Nm on block and 0.5Nm on linkage turns. As the block mass becomes big the acceleration and speed will be big too.
