| The bucket-wheel stacker reclaimer is a large scale continuous bulk material handling equipment, and because of its a wide range of advantages such as flexible action and the relatively low requirement of venue, it is more and more popular by many countries of the word. However, the bucket-wheel stacker reclaimer is often designed in in small batch production because the company must satisfy the customer’s requirements, special conditions and specific characteristics. With the rapid development and widely use of application o f modern design method for finite element analysis, optimization method, the reliability design, it is particularly urgent and important to implement the bulk material conveying machinery Lightweight and structure optimization. So,it is important to the manufacturing enterprises to design the production that meeting customer’s needs,and that’s a significant means to occupy a space in to the increasingly fierce competition market. It requires us to give more passion to innovate and reali ze the parametric design of products.This paper is based on the DQL800 / 800.35 bucket-wheel stacker reclaimer. Through the CAD Parametric design method to build the model and treat the minimum weight as objective function to optimize the bucket-wheel stacker reclaimer model. It ensures its strength, stiffness under the premise, and reduces the cost of production. In this paper, the main research work and achievements are as follows:1) The article research a design concept that based on top-down framework CAD parameterized which applied in CAD parametric design of the bucket wheel stacker reclaimer pitch part. Firstly, the original drive design parameters must be built by EXCEL and model framework should be built in the INVENTOR. Secondly, the original drive design parameters and frame model of design parameters must realize seamless link and data communication,thus framework model can be drive by the design parameters in the EXCEL table. Finally, input value of the optimal solution in the established 3D model that can get the goa l optimized size.2)The first step is to establish the mathematical model according to the structural characteristics which based on the structure and design theory of bucket wheel reclaimer on the pitch part. Taking the counterweight position and the uppe r hinge point as variable parameter and setting the strength stiffness of the various parts as constraints,the geometric relation equations can be listed. Operation with MATLAB,adjusting the geometric model and setting minimum weight as the objective funct ion,the optimal solution can be get. That is ensuring the pitch steel structure strength and stiffness and with the reasonable arrangement of the counterweight and the superstructure cutter location.3) Based on the structure and function of Bucket Wheel S tacker Reclaimer pitch part and combined with finite element analysis and optimization techniques,the boundary conditions and material setting parameters of the machine can be dealt in the software ANSYS. Input the optimal solution value to the mathematica l model to check the static analysis and the validation of the optimization results which is used to prove whether it can meet the design requirements and application.The research achievements of this topic could be well applied to bulk material conveying design field and increase machine stability to reduce production manufacturing cost and will have a good application prospect in engineering. |
