Q:Physics high school. Why does a spring fall to the lowest point and the acceleration a must be greater than the acceleration of gravity g ah. Seek expert: According to the conservation of mechanical energy, the object should be a free fall motion at the upper end of the spring

Q:What kind of material does spring have?: Alloy spring steel: alloy spring steel is used to make spring or other elastic parts of steel. Spring is generally under alternating stress, the fatigue failure is a common failure forms, therefore, alloy spring steel must have high yield and yield ratio (s/ b) and the anti fatigue performance of elastic limit, and to ensure that the spring has enough elastic deformation ability and can withstand greater load. At the same time, alloy spring steel also requires a certain plasticity and toughness, a certain hardenability, not easy to decarburization and not overheating. Some special springs also require heat resistance, corrosion resistance, or a stable elasticity over a long period of time. Medium carbon steel and high carbon steel can be used as springs, but because of its hardenability and low strength, it can only be used to make smaller cross-section, less force of the spring. Alloy spring steel can produce important spring with large cross section and high yield limit

Q:Can springs be used for support?: The following individual ideas do not represent the bestFriction is bound to damage,Gaskets can be used to prevent direct friction between the spring and gear to lubricate, optimize wear and prolong life.

Q:What's the manganese content of spring steel?: Carbon spring steelThe carbon content (mass fraction) of carbon spring steel is usually 0.62%~0.90%. In accordance with its manganese content is divided into general manganese content (mass fraction) (0.50%~0.80%), such as 65, 70, 85 and higher manganese content (mass fraction) (0.90~1.20%), such as 65Mn two categories.

Q:Is the car short spring good?: The factory is a hydraulic cylinder, and the damping force and the length of the expansion are matched with the length of the spring and the telescopic distance. Instead of changing the short spring will increase the load of the original vehicle hydraulic shock absorber, shock quickly destroy.

Q:I buy a spring made of 1.2mm steel wire from a hardware store that needs quenching: In general, hot bending spring coil spiral spring and disc spring of hot stamping, preferably in hot forming and quenching by the heat immediately. In this way, the heating and the decarburization degree of the spring can be omitted, and the surface quality of the spring can be improved both economically and at the same time.

Q:Is spring steel manganese steel?: With wings are not necessarily the "angel", also may be "bird". Steel not containing Mn elements is called manganese steel. Manganese steel refers to those with high strength steel, mainly used for impact, friction and extrusion, mainly wear and tear.

Q:Buffer spring buffer for automobile: The automobile spring buffer adopts the cushion principle to reduce the vibration produced by the vehicle during the running, and increase the comfort of the car. When the vehicle is equipped with a spring buffer, the problem of the spring of the shock absorber is effectively solved, the performance of the shock absorber is recovered, and the shock absorber and the suspension system are also protected, and the oil seal of the damping core is avoided. As long as the quality is good and the car to pick their own spring buffer models, can save at least 3 sets of shock absorber overhead, and a shock absorber to several hundred dollars or a thousand dollars, the long term of the owner is indeed a big burden. The new car spring buffer is a buffer of urethane material, not only simple and easy installation, no looseness of vehicle any screws, can make the body up 3 5cm, recovery of the original body height, improve the stability of road safety through deceleration and brake, greatly reduce the fatigue feeling after. The car cushion on the market are made of urethane material, suggest that you choose the buffer glue to the regular manufacturers purchase, on the market there are many inferior or three villages are often unable to get some of the results, some even hurt the shock absorber, shorten the service life of the damping rubber. My friend used Jinke rubber buffer for years should be full, very good quality.

Q:Cold rolled coil spring spring and difference ": Difference: the main annealing time is different. In the production process, is the first volume of coil spring and annealing, and spring is the first cold roll annealing, and then roll. Similar to cold rolling and hot rolling of steel.Note: spring making methodProduction method of cold rolled coil spring: to stress annealing, end surface grinding, (blast), (the whole school), (BKS), standing or forcing treatment, surface inspection and treatment.Production method of coil spring: blanking, end processing (rolled or forged flat), heating, coiling, quenching, tempering, grinding end to compression to (load test), shot peening (cleaning), coating.

Q:What's the spring material to?: 1, with alloy spring steel, respectively, there are several kinds of steel: 55Si2Mn or 50CrVA and 30W4Cr2VA, these alloy spring steel;2, manufacturing process:Coil the machine first into the spring and then proceed with the proper heat treatment process to get the spring you need.
