中空玻璃设备设计需要保证的三方面

(一)机械系统设计方法
(1) the design method of mechanical system
机械系统设计足研究组成系统的各部分及其内在联系，从整体系统出发，建基本设计原则，辩证解决设汁问题的一种设计分法。系统设计方法的主要思想是在设计过程中强调系统内部和外部环境的关系，强调整体系统和分系统的关系，并以之贯穿干整个设计过程。在分解与综合中要考虑各分系统联络关系的强弱及其与整体系统关联的完整性。
The mechanical system is designed to make all parts of the system and its internal relations. From the whole system, the basic design principles are built, and a dialectic method of designing the juice problem is dialectically solved. The main idea of the system design method is to emphasize the relationship between the internal and external environment of the system during the design process, and emphasize the relationship between the whole system and the sub system, and run through the whole design process. In decomposing and integrating, we should consider the strength of each subsystem's connection and its integrity with the whole system.
(二)优化设计方法
(two) optimal design method
优化设计方法是应用数学化原理解决实际问题的设计方法。针对菜—设计任务，以结构合理，工作性能，成本等为设计要求，在多种方案、多组参数、多种设计变量巾确定主要设计变量的取值，使之满足设计要求。在机械设计中，优化设计体现为传设计方案的确定和设计参数的确定。

The optimization design method is the design method to solve practical problems based on the principle of applied mathematics optimization. According to the design task, the design requirements are the most reasonable structure, the best work performance and the lowest cost. The main design variables are determined in various schemes, multi groups of parameters and various design variable towels so as to meet the optimal design requirements. In mechanical design, the optimal design is the determination of the best design plan and the determination of the best design parameters.

进行优化设计时，首先需要对具体的工程问题进行比较深入的了解，选择优化计算方法，构造合适的数学模型，寻找设计结果，找出设计参数。如减速器设计中，可以将材料省和结构紧凑作为设计目标。这样，在传动装置设计计算中．应该注意合理选择热处理工，参数选择时尽量使各部分的强度量合理。使用优化设计方法，可以加速设计过程、缩短设计周期，达到事半功倍的目的。
When optimizing the design, it is necessary to have a thorough understanding of the specific engineering problems, select the optimal calculation method, construct the appropriate mathematical model, find the optimal design results and find the best design parameters. For example, in the design of reducer, the most economical and compact structure can be taken as the design goal. In this way, in the design and calculation of transmission device, we should pay attention to selecting heat treatment workers reasonably, and optimize the strength of each part as much as possible when choosing parameters. By using the optimization design method, we can speed up the design process, shorten the design cycle and achieve twice the result with half the effort.
(三)可靠性设计
(three) reliability design
可靠性是指系统在规定时间内，在给定条件下完成规定功能的能力。产品的可靠性需有一个定量的表述，但可靠性的定量表述具有随机件，对任何产品来讲，在其可靠工作与失效之间，都具有时间上的不确定性；因此，对于不同类型的可靠性问题，就需要不同的表述方式，常见的有可靠度、无故障率、失效率、平均无故障时间等。合理规划分配各部分的可靠性指标，可以限度地发挥各部分的设计优势，保证产品在工作品质、技术标准和安全使用等文面达到高高质。
Reliability refers to the ability of the system to perform specified functions in a given time under specified conditions. The reliability of a product needs a quantitative expression, but the quantitative expression of reliability has random parts. For any product, there is a time uncertainty between its reliable work and failure. Therefore, different expressions are needed for different types of reliability problems. Failure rate, failure rate and mean time to failure. Reasonably planning the reliability index of each part of the distribution, we can maximize the design advantages of each part to ensure the quality of the product in the quality of work, technical standards and safe use.
