【摘要】：瀝青攪拌設備是道路養(yǎng)護專用設備之一，自80年代引進國外先進技術(shù)以來，國產(chǎn)瀝青混合料攪拌設備在拌合效率、加熱效率以及計量控制方面都有了很大提升。發(fā)展至今，瀝青攪拌設備在技術(shù)上已經(jīng)比較成熟，然而總體結(jié)構(gòu)設計卻沒有受到普遍關(guān)注。 如今用戶在選擇設備時不僅注重產(chǎn)品性能，輕巧美觀的外形設計越來越受到用戶的追捧。并且隨著產(chǎn)品的發(fā)展，小型化設備的產(chǎn)生也對結(jié)構(gòu)設計提出了更高的要求，然而國內(nèi)通常沿用傳統(tǒng)設計方法，設計出的結(jié)構(gòu)呈現(xiàn)出大、笨、粗的特點，不僅不具美觀性而且浪費了鋼材、增加了成本。在激烈的市場競爭環(huán)境下，采用一種先進科學的設計方法勢在必行。 根據(jù)國情，間歇式攪拌設備是我國攪拌設備的主流，本文以某公司生產(chǎn)的HZS150型框架結(jié)構(gòu)為研究對象,采用國際上通用的大型有限元程序ANSYS進行計算,考慮構(gòu)件間的空間相互作用,建立有限元模型,重點對以下幾個方面進行了研究： （1）根據(jù)HZS150樓體框架結(jié)構(gòu)實際受力情況，對其進行了靜力學分析，得出再生設備在空載和正常工作時，HZS150樓梯框架的應力分布及變形情況，結(jié)果驗證了：框架結(jié)構(gòu)的強度與剛度均滿足設計要求。 （2）對HZS150樓體框架結(jié)構(gòu)進行模態(tài)分析，得到前四階固有頻率及振型，觀察振型得框架結(jié)構(gòu)符合高層結(jié)構(gòu)的振動特性。 （3）在模態(tài)分析的基礎上進行諧響應分析，確定了“峰值”響應對應的頻率，明確了主振方向，從而分析出再生裝置與框架結(jié)構(gòu)不存在共振現(xiàn)象。 （4）建立HZS150型樓梯框架結(jié)構(gòu)參數(shù)化模型，對其進行優(yōu)化設計，使其在滿足剛度及強度條件下減輕了質(zhì)量，驗證了優(yōu)化方法的可行性。
[Abstract]:Asphalt mixing equipment is one of the special equipment for road maintenance. Since the introduction of foreign advanced technology in 1980s, the mixing efficiency, heating efficiency and metering control of domestic asphalt mixture mixing equipment have been greatly improved. Up to now, asphalt mixing equipment has been technically mature, but the overall structure design has not received widespread attention. Nowadays, users not only pay attention to product performance when choosing equipment, but also attract more and more attention from users for their light and beautiful appearance design. And with the development of products, the production of miniaturization equipment also put forward higher requirements for structural design. However, the traditional design method is usually used in our country, and the designed structure presents the characteristics of large, stupid and coarse. Not only is it not beautiful but also a waste of steel, increasing the cost. In the fierce market competition environment, it is imperative to adopt an advanced scientific design method. According to the national conditions, batch mixing equipment is the mainstream of the mixing equipment in China. This paper takes the HZS150 frame structure produced by a company as the research object and uses the large finite element program ANSYS, which is widely used in the world, to carry out the calculation. Considering the spatial interaction between members, the finite element model is established, and the following aspects are emphatically studied: (1) according to the actual stress situation of HZS150 building frame structure, the static analysis is carried out. The stress distribution and deformation of the HZS150 staircase frame are obtained when the regenerator is under no load and normal operation. The results show that the strength and stiffness of the frame structure meet the design requirements. (2) the modal analysis of the frame structure of the HZS150 building is carried out. The first four natural frequencies and modes are obtained, and the vibration characteristics of the frame structure are observed. (3) on the basis of modal analysis, harmonic response analysis is carried out, and the corresponding frequency of "peak" response is determined. The main vibration direction is determined and the resonance between the regenerator and the frame structure is analyzed. (4) the parameterized model of the HZS150 staircase frame structure is established and the optimum design is carried out. The quality is reduced under the condition of stiffness and strength, and the feasibility of the optimization method is verified.
