1. A wide-body light passenger project is a project that is completely designed based on data and utilizes the advantages of accurate digital data, fast modifications, and seamless interface with structural design. It seamlessly integrates shape, structure, and digital modeling throughout the project process. By introducing stages of structural feasibility analysis, the project achieves the goals of structural feasibility and satisfactory modeling, and releases the final design in the form of data. The inspection of the appearance CAS digital analog CheckList at each stage is extremely important. This article aims to provide an in-depth analysis of the rear door hinge design.2. Rear door hinge axis arrangement:The core focus of the opening motion analysis lies in the hinge axis layout and hinge structure determination. To meet the requirements of opening the rear door 270 degrees, the hinge must be flush with the CAS surface and have a suitable inclination angle. The following steps outline the analysis process:a. Determine the Z-direction position of the lower hinge, which considers the space for reinforcement plate arrangement and welding process size.b. Arrange the main section of the hinge based on the Z direction of the lower hinge and determine the four-axis positions of the four-linkage system.c. Determine the inclination angle and forward inclination of the four axes using the method of conic intersection.d. Determine the position of the upper hinge based on the distance between the upper and lower hinges.e. Arrange the main sections of the upper and lower hinges in detail, considering manufacturability, fit clearance, and structural space of the four-bar linkage mechanism.f. Perform DMU movement analysis to analyze the back door's movement and check the safety distance during the opening process.g. Adjust the parameters of the hinge axis inclination angle, forward inclination angle, connecting rod length, and distance between the upper and lower hinges to analyze the opening feasibility of the rear door. If adjustments are unsuccessful, the CAS surface needs to be modified. 3. Rear door hinge design scheme:The rear door hinge adopts a four-bar linkage mechanism. Due to the adjustment in shape, three design options are proposed:3.1 Scheme 1: Ensures alignment with the CAS surface and parting line, but has disadvantages in terms of appearance and structural risks.3.2 Scheme 2: Protrudes the hinges outwards to eliminate gaps with the rear door in the X direction and provides structural advantages.3.3 Scheme 3: Matches the outer surface of the hinges with the CAS surface but has a large gap between door links.After a comparative analysis and discussions with modeling engineers, it is determined that the third scheme is the optimal solution.4. Summary:Designing the hinge structure requires considering various factors such as structure, shape, and optimization. The forward design approach in the CAS design stage allows for meeting structural requirements while maintaining a high-quality appearance. The third scheme is chosen to minimize changes to the outer surface, ensuring consistency in the modeling effect.

What to Do When the Sliding Door Track is BrokenIf you find that your sliding door track is broken, there are a few steps you can take to fix it:1. Check for any damage to the pulley. If the pulley is damaged, it needs to be replaced with a new one. Make sure to remove the old pulley and install the new one correctly. Also, inspect the track for any foreign objects that may be causing the issue. If you find any, simply remove them from the track. Additionally, if the track is deformed, you can try using tools to straighten it out.2. Lubricate the sliding door during installation and regularly in the future. This is important to reduce the friction and prevent the track and pulley from becoming heavy and noisy over time. Without proper lubrication, the door may fail to open properly or even damage the door handle. Regular lubrication will ensure smooth movement and longevity.How to Repair a Broken Slideway on a Plastic Steel Sliding DoorTypically, the track under the sliding door is not prone to breakage. However, if you're unable to push the door, it may indicate that the wheel beneath is broken or the wheel adjustment screw is stuck. In such cases, you can remove the door and check it yourself. If the wheel is broken, simply replace it. If the screw is stuck on the wheel, use a hex wrench to loosen it. The wheel can usually be purchased from places that sell sliding doors.Additional Tips:1. Keep the track clean on a daily basis and be cautious of heavy objects hitting it. Clean the track regularly using a non-corrosive cleaning fluid.2. If the mirror or board is damaged, seek help from professional personnel for a replacement.3. Ensure the anti-jump device is functioning effectively to maintain safety.4. If you notice a gap between the door body and the wall, have a professional adjust the lower pulley screw to achieve a tight fit.References:- Baidu Encyclopedia: Sliding doorPlease note that the rewritten article has a similar theme and word count to the original one, as requested.

Full extension drawer slides are a very practical home decoration item, which can effectively improve the efficiency of home use. However, when many people choose full extension drawer slides, they often face a problem, that is, how to choose full extension drawer slides with the correct length. This is not an easy problem, as choosing the wrong length can be inconvenient or even dangerous. Below, this article will introduce how to choose the correct length of full extension drawer slides to help you buy the right product. First of all, we need to know what the length of the full extension drawer slides is. The length of full extension drawer slides refers to the actual length of the drawer slide rail, which includes the end installed on the wall or the inner wall of the wardrobe and the length of the slide rail protruding. Generally speaking, the length of full extension drawer slides has many specifications, ranging from 200mm to 1200mm, so you must choose according to the actual situation when choosing. Secondly, what we need to know is the size and installation method of the full extension drawer slides. When choosing the length of full extension drawer slides, we also need to consider the size of the drawer and how it will be installed. The larger the drawer size, the longer the required full extension drawer slides. At the same time, when choosing the length of full extension drawer slides, we also need to consider the installation method, because some installation methods may affect the length selection of full extension drawer slides. The biggest problem lies in the range of the length of the full extension drawer slides. If the length is selected to be large, it will be more difficult to install. If the length is selected to be small, the drawer will run off or have jamming, which will affect the use Experience, but also cause unnecessary damage. In addition, when choosing the length of full extension drawer slides, we also need to consider the load-bearing capacity of the shelf. If the drawer is full of items, the pressure on the full extension drawer slides will be very high, so we need to choose full extension drawer slides with a greater load capacity. Generally speaking, the load capacity of full extension drawer slides will be described in detail in the product manual. In addition to the above points, we also need to pay attention to the choice of brands and purchase channels. If you choose a brand with a good reputation, the quality will be relatively guaranteed. At the same time, when purchasing full extension drawer slides, we must also choose regular purchase channels, so as to avoid the emergence of fake and inferior products. When choosing the correct length of full extension drawer slides, we need to consider factors such as the size of the drawer, installation method, load capacity, brand, and purchase channel. Only by comprehensively considering these factors can you choose the full extension drawer slides that suit you and improve the comfort and efficiency of home life.
