Abstract: One of ideal methods that deal with variable structure system is treating variable structure problem as load or relieving of constraints. The simplest instance is ideal load of bilateral constraints, which means that there is only ideal constraint force during load. From the point of view of analytical mechanics, the theory of ideal load of bilateral constraint is given. The advantage of the theory is that it reveals mechanical mechanism of ideal load of bilateral constraint and it is more convenient for extension.
