APPLICATION SIMULATION AND COMPUTER SELECTION ACE has developed a sophisticated suite of computer software. By combining application data with a shock absorber s design parameters, ACE engineers can create an accurate picture of how a particular shock absorber will perform under any set of application conditions. Peak reaction force, peak deceleration, time through stroke and velocity decay can be plotted with extreme accuracy (see below). The user benefits by having any guesswork taken out of sizing decisions and by knowing before installation, exactly how his shock problem will be solved. Simulation can also be used to maximise the performance of ACE adjustable models by predicting the ideal adjustment setting for a particular group of operating conditions. Copies of our computer selection programme are available, free of charge. The software provides quick and easy selection of the correct ACE shock absorber for your application. For more complex or unusual applications full technical support and advice is always freely available.

9 Shock Absorber Function Virtually all manufacturing processes involve movement of some kind. In production machinery this can involve linear transfers, rotary index motions, fast feeds etc. At some point these motions change direction or come to a stop. Any moving object possesses kinetic energy as a result of its motion and if the object changes direction or is brought to rest, the dissipation of this kinetic energy can result in destructive shock forces within the structural and operating parts of the machine. 9 Kinetic energy increases as the square of the speed and the heavier the object, or the faster it travels, the more energy it has. An increase in production rates is only possible by dissipating this kinetic energy smoothly and thereby eliminating destructive deceleration forces. Older methods of energy absorption such as rubber buffers, springs, hydraulic dashpots and cylinder cushions do not provide this required smooth deceleration characteristic they are non linear and produce high peak forces at some point during their stroke. The optimum solution is achieved by an ACE industrial shock absorber. This utilises a series of metering orifices spaced throughout its stroke length and provides a constant linear deceleration with the lowest possible reaction force in the shortest stopping time.

Stopping with Rubber Buffers, Springs, Dashpots or Cylinder Cushions Result: Raw Material Production Loss of Production Machine Damage Increased Maintenance Costs Increased Operating Noise Rubber Buffer Finished Product Scrap Higher Machine Construction Costs Stopping with ACE Shock Absorbers Raw Material Production ACE Shock Absorber ACE Shock Absorber Finished Product Benefits: Increased Production Increased Operating Life of the Machine Improved Machine Efficiency Reduced Construction Costs of the Machine Reduced Maintenance Costs Reduced Noise Pollution Reduced Energy Costs 9

10 Comparison of Damping Systems Stopping Force (N) Comparison Hydraulic Dashpot Pneumatic Cylinder Cushions Springs - or Rubber buffers 1. Hydraulic Dashpot (High stopping force at start of the stroke). With only one metering orifice the moving load is abruptly slowed down at the start of the stroke. The braking force rises to a very high peak at the start of the stroke (giving high shock loads) and then falls away rapidly. 2. Springs and Rubber Buffers (High stopping forces at end of stroke). at full compression. Also they store energy rather than dissipating it, causing the load to rebound back again. ACE Industrial Shock Absorbers 3. Air Buffers, Pneumatic Cylinder Cushions (High stopping force at end of stroke). Due to the compressibility of air these have a sharply rising force characteristic towards the end of the stroke. The majority of the energy is absorbed near the end of the stroke. Stopping stroke 4. ACE Industrial Shock Absorbers (Uniform stopping force through the entire stroke). The moving load is smoothly and gently brought to rest by a constant resisting force throughout the entire shock absorber stroke. The load is decelerated with the lowest possible force in the shortest possible time eliminating damaging force peaks and shock damage to machines and equipment. This is a linear deceleration force stroke curve and is the curve provided by ACE industrial shock absorbers. Energy Capacity Reaction Force (stopping force) Stopping Time ACE Shock Absorber Hydraulic Dashpot ACE Shock Absorber Force (N) Force (N) Q v (m/s) t Hydraulic Dashpot ACE Shock Absorber t Hydraulic Dashpot Q Stopping stroke Stopping stroke Stopping time Assumption: Same maximum reaction force. Result: The ACE shock absorber can absorb considerably more energy (represented by the area under the curve.) Benefit: By installing an ACE shock absorber production rates can be more than doubled without increasing deceleration forces or reaction forces on the machine. Assumption: Same energy absorption (area under the curve). Result: The reaction force transmitted by the ACE shock absorber is very much lower. Benefit: By installing the ACE shock absorber the machine wear and maintenance can be drastically reduced. Assumption: Same energy absorption. Result: The ACE shock absorber stops the moving load in a much shorter time. Benefit: By installing an ACE shock absorber cycle times are reduced giving much higher production rates.

11 The Benefits of Good Design ACE Shock Absorber Other Shock Absorber Outer body and Pressure chamber with closed rear end (one-piece) Snap Ring (Outer body and inner pressure chamber made from tube stock.) 11 ACE builds its shock absorbers with closed end/one piece bodies and inner pressure chambers which greatly reduces the chance of sudden failure or machine damage in the event of an overload. 1. What happens with an overload or gradual oil loss? Harder bottoming out force becomes apparent. The shock absorber continues to work and can be replaced then or at the end of the shift. 2. The Cost: Remove and replace the shock absorber. Refill with fresh oil or repair. Some other manufacturers use bodies and inner pressure chambers made from tube stock.the internal parts are held in by a snap ring etc. which then takes all the load and can fail suddenly and catastrophically. 1. What happens with an overload or gradual oil loss? The snap ring breaks or is extruded due to excessive force. Machine damage!! Equipment Stops!! Production Halted!! Emergency Repair!! 2. The Cost: Remove and replace the shock absorber with new one (repair not possible). Cost 75 to 300 depending on size. Additionally: Production Loss: Machine repair: Total cost: 50 to 0 Total cost: 500 to 00 v = 2 m/s v = 1,5 m/s v = 1 m/s v = 0,5 m/s v = 0 m/s n n n n *4 *3 *2 *1 *0 P = 400 bar P = 400 bar P = 400 bar P = 400 bar P = 0 bar * The load velocity reduces continuously as you travel through the stroke due to the reduction in the number of metering orifices (*) in action. The internal pressure remains essentially constant and thus the Force vs. stroke curve remains linear. F = Force (N) P = Internal pressure (bar) s = Stroke (m) t = Deceleration time (s) v = Velocity (m/s) n n n F/P n n n v s/t t 11

12 Built in Safety 12 Industrial shock absorbers and automobile braking systems have two crucial functional similarities: 1. Both should bring a moving mass quickly and safely to rest without any recoil or bounce back. 2. Both must never suddenly fail without warning. ACE industrial shock absorbers are built to the highest quality. Shock absorber bodies and inner pressure chambers are fully machined from solid high tensile alloy steel. This gives a completely closed end one-piece pressure chamber with no seals or circlips being necessary. The advantage of this design concept is that the ACE shock absorber is able to withstand much higher internal pressures or overload without damage, giving a very high safety margin. The chance of a sudden failure due to overload etc. is effectively ruled out. Integral Positive Stop Piston Rod high tensile steel hardened and corrosion resistant. Bearing maintenance free, and self-lubricating. Shock Absorber Body massively built one-piece body with closed rear end. Fully machined from solid steel to ensure total reliability. Seals only one dynamic seal. Hermetically sealed rolling diaphragm sealing system. Piston made from powdered metal self-lubricating and friction free. Pressure Chamber made from high tensile steel, hardened and nitrided. Fully machined from solid with closed rear end to withstand internal pressures up to 00 Bar. Self-Compensating Industrial Shock Absorbers are maintenance free, self-contained hydraulic devices with multiple metering orifices which extend through the complete stroke length. After the moving load contacts the shock absorber the piston moves gently back creating an immediate pressure rise in the pressure chamber. The hydraulic oil behind the piston can initially escape through all the metering orifices. The number of metering orifices in action decreases proportionally to the distance travelled through the stroke. The impact velocity of the moving load is smoothly reduced. The internal pressure and thus the reaction force (Q) remain essentially constant thoughout the complete stroke length providing a constant deceleration rate or: Linear Deceleration 12
