Anonymous users2024-02-06Mechanical design is an important part of mechanical engineering, the first step of mechanical production, and the most important factor in determining mechanical performance。The goal of mechanical design is to design the best machine under various limited conditions (such as materials, processing capacity, theoretical knowledge and calculation methods, etc.), that is, to make an optimal design.
Optimal design requires a combination of many requirements, generally including: best working performance, lowest manufacturing costs, minimum size and weight, maximum reliability in use, lowest consumption and least environmental pollution. These requirements are often contradictory, and their relative importance varies depending on the type of machinery and the purpose for which it is used.
Main process. 1. Formulate design tasks according to user orders, market needs and new scientific research achievements.
2. Preliminary design of the trembling bucket. It includes determining the working principle and basic structural form of the machinery, carrying out motion design, structural design and drawing preliminary general drawings and preliminary review.
3. Technical design. This includes revising the design (based on preliminary opinions), drawing up all components and new general drawings, and a second review.
4. Work drawing design. Including the final modification (according to the second instance opinion), the drawing of all working drawings (such as parts drawings, component assembly drawings and drawings and other rolling holes), the development of all technical documents (such as parts list, wearing parts list, instructions for use, etc.).

Anonymous users2024-02-04The basic tasks of the overall design of construction machinery include the development of new products and the transformation of old products.
Its purpose is to provide the market with high-quality, high-performance, high-efficiency, low-energy, low-cost mechanical products, in order to obtain the greatest economic and social benefits.
Construction machinery is an important part of the equipment industry. Generally speaking, all the mechanical equipment necessary for the comprehensive mechanized construction engineering required for earthwork construction engineering, pavement construction and maintenance, mobile lifting and loading and unloading operations and various construction projects is called construction machinery.

2. Modular hierarchical combustion controller software system: The software system is built on Linux, a real-time multi-task operating system based on open source, and adopts hierarchical and modular structure design to realize the openness of the software system.
3. Fault diagnosis and safety maintenance technology of the robot: Diagnosing the fault of the robot through various information and maintaining it accordingly is the key technology to ensure the safety of the robot.
4. Networked robot controller technology: At present, the application engineering of robots has developed from a single robot workstation to a robot production line, and the networking technology of robot controllers has become more and more important. It can be used for communication between robot controllers and robot controllers with the host computer, which is convenient for monitoring, diagnosis and management of the robot production line.

First,Q&A marketingIt is a very novel marketing method, mainly through the form of questions and answers, to promote the corresponding products to potential customers, so that customers can quickly browse the specific content of the question and answer, and get the information they need. The most important thing in Q&A marketing is to show what customers care about, ask questions from the customer's perspective and position, and solve the customer's most difficult problems. >>>More
1. The flavonoids rich in propolis have a good effect of lowering blood lipids, reducing the permeability of capillaries, softening blood vessels and protecting blood vessels, which can protect blood vessels from becoming brittle and hard prematurely, losing elasticity, and effectively purifying blood. >>>More
Propolis softgels are made of purified propolis, processed and dissolved, added to rapeseed oil in an appropriate proportion, and made in standard GMP workshops, propolis softgels must be made of purified propolis, because the content of heavy metals and some impurities in wool gum is higher, and the purified wool gum removes heavy metals, and propolis softgels are easier to be absorbed by the human body, and are easy to carry and preserve. >>>More
The word fire is often heard, especially in summer, the weather is hot in summer, the water in people's bodies is often evaporated or sweated out, we know that the specific heat capacity of water is very large, he can regulate the temperature of the human body very well, once there is a lack of water, the temperature of the human body will rise and lead to fire, in addition to the fire caused by hot weather, there is also too spicy food will also be on fire, these are common sayings, Chinese medicine has different statementsSo what is the fire in Chinese medicine and what are the types? In traditional Chinese medicine, the fire generally refers to some symptoms of the fire, and its types are, liver fire, stomach fire, heart fire, etc. >>>More
