1 ) First, according to modern design manual hoist and electric cable hoist, with a small frame integrated parametric design system to generate three-dimensional solid model of a small frame 2 ton chain hoist; then thought simplified finite element model of the small frame manual hoist as a whole , using the finite element software analysis of the original car frame in the most unfavorable conditions of stress and strain distributions and the inherent electric cable hoist vibration characteristics 2 ton chain hoist, found deficiencies in the design of the car and take a flexible approach to deal with in the process according to the problems encountered electric cable lever hoist.
2 ) According to the results , the original car for loose structure , such as excessive weight status of the car lightweight structural redesign .In the main components is analyzed, 2 ton chain hoist designed for small frame structure analysis, the new car program meets lightweight design standards.
3 ) The maximum structural rigidity as the goal, volume , static equilibrium structure as the constraints on the use of topology optimization method to optimize small frame manual hoist, small frame parts cloud density derived optimized structure , in accordance with this cloud electric cable block, you can analyze the structure of lightweight 2 ton electric chain blocks parts and related details.
4 ) the use of designs and sizes to optimize processes and assembly characteristics combined with the design requirements of small lightweight frame structure drawn 2 ton chain hoist, and then repeated use optimization software to improve and optimize the little frame mechanics and modal analysis 10 ton electric cable hoist , verification and optimization improvements reasonableness of the results , the conclusion that the final design of the structure of the 160 tons of lightweight small frame .
Small frame for overhead crane design calculations electric cable hoist manufacturer, it is to abandon the traditional simplified calculation method Charpy or box section , using the finite element method to calculate the solid model will be small parts of the frame , with separate dynamics and static analysis , given the local stress , strain , high reliability of the results obtained , while providing an important manual hoist basis for the re- design of small lightweight frame .
Elaborated on the background and significance of the subject electric cable hoist supplier, analysis and : with tension and compression instead of bending standards ; reasonable layout support manual hoist; reasonable shape design criteria section 10 ; with ribs or partitions criteria ; satisfaction with pre-deformation harmful distortion criterion ; improve surface contact stiffness criteria electric cable hoist.
