Mechanical design is a complex undertaking, requiring many skills. Extensive relationships need to be subdivided into a series of simple tasks. The complexity of the subject requires a sequence in which ideas are introduced and iterated. To design is either to formulate a plan for the satisfaction of a specified need or to solve a problem.

The critical speed (see Section ) is the rotational speed at which dynamic forces acting on the system cause it to vibrate at its natural frequency. Operation of a shaft at this speed can cause resonance and significant vibrations that can severely damage a machine and is therefore a key consideration in the design of a rotating machine. Torsional and lateral deflection both .

Design of superelevation There are four steps involved in the design of superelevation. And they are, Step 1: Calculate the superelevation necessary for 75% design speed and assume No lateral friction is developed If e value is less than e max =, provide calculated e value. Otherwise proceed to next step Step 2: When e cal > e max Provide e = e max = in this .

design speeds of 70 mph (110 km/h) or more are used. Appearance The general controlling factor for appearance of a sag curve is K ≥ 100 for English units and K ≥ 30 for metric units for small to intermediate values of A, which corresponds to speeds of 50 mph (80 km/h) and greater. Thus, for design speeds less than 50 mph (80km/h) the designer will want to strongly .

The whirling or critical speed is therefore. For a simply supported beam with a central mass K = 48 .. See examples below . Substituting ω c 2 for KEI /mL 3 in the above equation for y results in the following equation which relates the angular velocity with the deflection. This is plotted below.. This curve shows the deflection of the shaft (from the static deflection position) at any speed ...

· For the first critical speed to become a concern at four pole speed, shaft deflection would have to be greater than A pump with a shaft deflection of but driven by a two pole motor (3,600rpm) will operate well above its first critical speed. As I mentioned earlier, this is not a concern in constant speed appliions because ...

forward, design for power (torque and speed), then shaft loads, and finally mixer dynamics. For larger systems above 100 hp it may be prudent to perform a mixer/vessel system modal analysis (finite element anaylsis (FEA)) to avoid unexpected interactions. The simplicity of this sequence however does not address the compliions introduced by multiple process requirements, .
