Methods for Calculating Mass Properties
Adams/View uses two different methods to calculate mass properties. If you modify the number of sides Adams/View uses to define a part’s geometry, such as cylinder, frustum, or torus, Adams/View may use a different method to calculate the part’s mass properties depending on the number of sides, as explained below.
• If the number of sides is greater than or equal to the default number of sides (usually 20), Adams/View calculates the mass using an analytical equation for the geometry volume. It uses a true solid that the name of the part indicates.
• If the number of sides is less than the default, Adams/View uses a prismatic solid, which you actually see on the screen, to calculate mass properties. This method is slower but gives more accurate results. For example, if you change the number of sides of a cylinder from 20 to 3, the geometry on the screen is of a triangular solid. This solid’s mass properties will be significantly different that a cylinder’s mass properties.
