Spreadsheet to calculate center of gravity (this sheet) and angle of tilt (sheet 3) of a system given the locations and centers of gravity of individual products in a rack

Local center of gravity location(referenced to product origin)

Product origin location within system

XLcog YLcog ZLcog

Calculated System Center of Gravity(referenced to system origin)

To use: Determine the weight of each product and record in column C. Then determine center of gravity of each product relative to its local origin and record those numbers into columns E, F, and G. Local product origin should be the front lower left of the product with its rack ears on. x direction is along the horizontal axis in normal rack mounting position. y direction is in the vertical direction. z direction is front to rear. Lastly determine where each local product origin will be located with respect to the system's origin and record those numbers in columns I, J, and K. Sheet 2 of this spreadsheet will help you determine this location in the system using Agilent racks. Make sure that local center of gravity axes (XLcog, YLcog, ZLcog) are parallel to system axes (Xloc, Yloc, Zloc). Don't forget to put the rack in as one of your products (see sheet 2 for info). Units can be whatever you choose, but you must be consistent. Millimeters (mm) are recommended since all dimensions on sheet 2 are in mm. If you need to convert, there are 25.4mm in 1 inch.

Note: This spreadsheet will help determine an APPROXIMATE center of gravity of a system and an APPROXIMATE angle at which the system will tip. It will be difficult to determine the exact center of gravity without adding in all the cables and rack mounting hardware (such as rails or slide kits). Since the major contributors to a change in center of gravity are the rack(s) and the products that go in them, this solution will give a close approximation. The spreadsheet will help you determine if added weight on the bottom of the rack will help stabilize the system during movement up ramps or if it is best to push the system up a ramp from one face or another.

To add more products, insert rows before row 9, and make sure you extend the calculations in columns O, P, Q, R, S, and T down into the newly inserted rows.

However, this spreadsheet is not to be substituted for a direct measurement of the angle at which a system will tip.

This sheet helps you find the location of a product in an Agilent rack. Each set of numbers in the table indicates a position on the front of the rack from an origin in the front lower left corner of the rack's frame (the system origin). These locations are possible origins of products to be placed in the rack. Origins for each product should be the front lower left corner of the product, including rack ears, and each product's center of gravity should be relative to that point. For each product, copy and paste the Xloc, Yloc, and Zloc locations on this sheet to the first sheet into columns I, J, and K.

For each product, copy and paste the Xloc, Yloc, and Zloc locations on this sheet to the first sheet into columns I, J, and K.

Notes: 1. For products mounted in the rear of the rack, determine the local center of gravity from the front lower right corner (instead of the left) and change the ZLcog on sheet 1 to a negative value. Then use the values given on this sheet for Xloc and Yloc, and change the Zloc value to 716mm. 2. For multiple bay systems, add 600 to the number in the X column for the products in the second bay. Likewise, add 1200 to the number in the X column for products in the third bay.

The Center of Gravity of the rack (an Agilent Rack) is referenced from the lowest left point on the front frame of the rack, but the rotation point for tipping would occur at the wheels. The tip angles are calculated using this rotation point. Input the values from sheet 1 for the System Center of Gravity under Xsyst, Ysyst, and Zsyst. This sheet then indicates the angle from vertical at which each side would begin to fall onto that side.CoG = Center of Gravity, TP = Tip Point
