Application of the hottest Proengineer 3D software

Application of pro/engineer three-dimensional software in the pipeline design of air conditioning and refrigeration system

content abstract: with the continuous expansion of the international and domestic market, all air conditioning manufacturers must match a variety of compressors on a certain type of air conditioner, and the subsequent automatic redesign of refrigeration system pipeline has the disadvantages of long cycle, low efficiency, large deviation and so on under the traditional two-dimensional software such as au-tocad platform, So at present, many manufacturers have begun to use 3D design software to design air conditioning and refrigeration systems. 1 preface

with the continuous emergence of advanced manufacturing technology, the fierce market competition in air conditioning manufacturing industry presents different characteristics. Improving the market competitiveness of products, shortening the life cycle of products, reducing the cost of product development, and enriching the variety of products have become the focus of market competition among various air conditioning manufacturers. As the international market is a challenge and the domestic market continues to expand, each air conditioning manufacturer must match a variety of compressors on a certain type of air conditioner, and the subsequent independent redesign of the refrigeration system pipeline has the disadvantages of long cycle, low efficiency, large deviation and so on under the traditional two-dimensional software such as au-tocad platform. Therefore, many manufacturers have begun to use three-dimensional design software to design the air conditioning and refrigeration system. With its vivid interactive interface, highly parameterized design concept and intelligent analysis ability, especially taking pro/engineer as an example, 3D software gets rid of the shortcomings of boring, solid and spatial sense of previous 2D design, and provides the possibility for efficient and high-quality development

2 use pro/e to design pipeline entities

pro/engineer provides a special management design module pro/piping. According to the designed outdoor sheet metal model (Figure 1), we use the pro/piping function to design the outdoor pipeline of the air conditioner (Figure 3). The traditional pipeline design method is mainly to measure on the real object, and then repeatedly make piping samples for installation and verification, which has a long design cycle. The use of pro/piping for pipeline design solves this problem very well. Due to its full parameter three-dimensional design mode, engineering developers not only have overall consideration of the processibility of the pipeline and the location of the three-dimensional space, but also more comprehensively consider the impact of vibration and noise caused by the fall and transportation of the pipeline, Therefore, the first-time success rate and reliability of pipeline design are improved, and the development time is shortened

at the same time, due to the high generalization and standardization of parts, and the similar appearance of the compressor, we can use pro/assembly's structure to rebuild the four-way valve component (Figure 2), then create a new four-way valve component in save a copy, and then assemble it with mate, align, insert, orign, etc. By modifying the parameters of the pipeline, the new four-way valve components can be initially built soon, which greatly reduces the time of the early conception and design of the pipeline components. This is also the benefit of high parameterization of pro/e

because pro/e has the above characteristics in design, it can not only ensure the design quality, but also greatly reduce the number of samples in shortening the development cycle. This is a significant reduction in development costs. Similarly, by using the assembly mass properties that make the experimental machine unable to operate normally, the volume, surface area, mass and other data can be obtained by inputting the material density of the component (Fig. 4), which is very useful for the cost budget of pipeline components in the early stage. In particular, the recent sharp rise in the price of raw materials, material cost control has become a major part of cost control. Designers and developers can use this function to effectively control the cost at the early stage of design

3 use pro/e to conduct finite element analysis of pipeline entities

the above mainly discusses the role of pro/engineer in pipeline design from the mechanical aspect. It is obvious that it is particularly prominent in pipeline model design, early cost control, reasonable positioning of pipeline components, design changes, etc., which is not comparable to two-dimensional software. What about the internal condition and vibration of the pipeline? We then take pipeline analysis as an example to explore the idea of pro/mechanica in functional simulation that under the tension of amorphous plastic ≤ 0.3%, pro/engineer can extend and contract without fatigue failure (such as vascular grafts) or bend without fracture (such as electrode lead insulator)

Figure 5 is the flow chart of pro/mechanica's performance simulation of the pipeline:

(1) establish the geometric model of the pipeline through pro/e, which we have talked about earlier

(2) select the type of model in the login interface of pro/m, and the default type of pro/m is entity. The pipelines we design through pro/e are generally solid

(3) to set the characteristics for the model, it is not necessary to set the characteristics of each part of the model the same. For example, under the four-way valve component, we can set the four-way valve as brass, and other pipelines as red copper. For the stress analysis of pipeline, necessary parameters such as young's modulus and Poisson's ratio must be set. The database in pro/m software package has the data of conventional materials (such as copper, aluminum, iron, etc.) to call. Determine the constraints of the model. For example, in stress analysis, some determined points or points that can move freely along a specified direction can be set as constraints. Pro/customloads for custom load input
