Tower and middle-aged man

Sea transport will involve moving it to Southeast Asia, where there are the necessary facilities; it looks like this: due to modular transportation, the tower needs to be mounted on a frame on the ship, so that the entire factory can be transported by sea as a single unit. In the diagram, on the left is the vaporization furnace, weighing about 900 tons ； On the right is the synthesis tower cooler, weighing about 1,400 tons. Among them, the Y direction is the forward direction of the ship; it is relatively stable with an acceleration of 0.039g. The X direction corresponds to the ship’s width, where the acceleration is relatively high, at 0.2g. Consider a wind pressure of 600 Pa. Due to strong winds and waves, a 7° ship tilt is considered. Calculate the loads at the two supports and consider whether their anchor bolts are sufficient. ““It is a tower; if transported by sea, it will be moved to Southeast Asia” — by Zhuangzi. Preliminary approach to determining whether the bolts are sufficient: 1. Separate the tower and conduct preliminary calculations in PVELite, adjust the weight percentages, set the mass of the equipment at 900 and 1400 tons, and enter appropriate values for seismic loads based on G-loading. 2. By finding the wind and seismic data for each section in the PVelite calculator, it is possible to obtain the horizontal forces and moments for each section. 3. Divide the horizontal force by the length of the entire cross-section to obtain the uniformly distributed load. 4. Query the calculation sheet to obtain the centroid position H, and calculate the bending moment at the centroid using the formula G*H*sin7. 5. Use Ansys’ Beam188 element to calculate the reaction forces and bending moments of the combined device. The boundary conditions are the uniformly distributed loads and moments obtained from 3 or 4 bars. 6. Obtain the calculation results from ANSYS, and input the reaction forces and moments into an EXCEL sheet to determine whether the number of bolts is sufficient. Is it possible to add guides? As a preliminary estimate, the shear force diagram is as follows: and the bending moment diagram is as follows. Based on the results, the load at the lower part will be relatively large; therefore, it is considered to add guides somewhere at the top to share this load. How should guidance be considered? First, in the case of no guidance, the displacement at the guided node position is 44.8 mm. Assume that the shell displacement is restricted here. Calculations show that the guide structure carried a load of over 700 tons. It is greater than the load on the two supports at the bottom. Of course, the guidance for such large-scale equipment generally isn’t based on a fixed point. Instead, there is some distance from the device; the guidance only comes into effect when the device is moved to a certain position. A song describes this process in detail: Come a little closer, let’s hold hands; be a little braver, and I’ll go with you. What are you waiting for? Time is running out; if we go any further, we can only remain friends—by SHE, “Lover Not Yet”. As one gradually gets closer to you, how is the load distributed during that process of approaching the device? By varying the gap from 0 to 44.8, the horizontal thrusts on the synthesis tower, gasifier cooler, and guide were calculated, yielding the following results. In other words, the guides completely restrict the tower’s displacement; at this point, the guides bear the maximum load. As the constraints imposed by the guide on the tower are relaxed, the load on the guide gradually decreases, while the load on the equipment itself increases. The reason for this is that, compared to the frame, the tower itself is too rigid; in order to support the tower, the guide structures have to bear incredible loads. We hope to turn the tide and avert disaster, to stabilize what is on the verge of collapse; yet, after all, \"a single pillar cannot hold up the sky.\" So in the end, the guidance was given up. The final solution is: the tower must stand on its own. As heaven changes through movement, a gentleman should strive for self-improvement without cease——From The Book of Changes. A middle-aged man stared at this tower for a long time, finding it increasingly resembling a human being. Confucius said, “When the Way cannot be practiced, one must float on a raft across the sea.” This tower, floating on the sea, must also be self-reliant and strong; without any support to rely on, it must withstand the winds and waves, holding up the sky with its own strength. This scene closely resembles that of a middle-aged man, and it resonates with me...... I remember there was a typhoon this summer; the wind was so strong that many trees fell down. All the pedestrians around took cover. But 53-year-old truck driver Zhou Rong rushed out, as his pickup truck was still parked outside. The people around him said, “Have you lost your life?” ”But fearing that the truck might be overturned by the strong wind, he ignored their warnings and rushed out to confront the truck he had bought just over ten days earlier. But in the face of the fierce typhoon, he simply couldn’t withstand the pressure; with a loud crash, the truck crushed him, and he died on the spot, with blood spreading everywhere. It is said that the next day was his 54th birthday. Some netizens mocked him for risking his life over a pickup truck worth only a few tens of thousands of yuan; it wasn’t worth it, they said. Perhaps this car is one that he could only afford by saving up all his life’s earnings; perhaps it is the tool he relies on to make a living. What is certain is that without it, his world would collapse. Although he no longer has to hold on anymore, their world has collapsed. A netizen put it bluntly: “The saddest thing about poverty is that one always feels that one can only face everything by risking one’s life; life is worth less than paper.” ” In middle age, men don’t have any time for themselves; they have to take care of their families as well as manage their relationships with friends. After agreeing to a friend’s invitation, his family sent a message urging him to act quickly; the man could only say, \"I’m really sorry, something has come up – let’s meet again next time.\" ” In middle age, men finally get the opportunity to take on important responsibilities; they devote themselves wholeheartedly to their work, and their careers thrive. Yet as important milestones approach, their bodies send out warning signs, and all the man can say is, “It’s fine, I’ll deal with it once I’m done with this.” ” By middle age, men are usually key members of their companies. Yet faced with criticism from their supervisors, they dare not leave on the spot as they did in their youth, simply because there is a whole family that depends on them for support. ” This is the endurance and helplessness of middle-aged men. Men in middle age often feel lonely, because as soon as they open their eyes, there are people around them who rely on them, yet there is no one on whom they can rely. ---By Eileen Chang: If even towers are like this, how can humans endure it?
