A carrier device capable of varying contact damping with pressured displacement, wherein the second force-receiving structure (2) provide one end thereof as a carrying end (4) for bearing a load or stress, that the second force-receiving structure (2) has a limiting structure (11) extended therefrom and linked thereto that works with a pre-stressed structure (3) to form a first force-receiving structure (1), and that the first force-receiving structure (1) and the second force-receiving structure (2) jointly transfer the pressure from the load or stress to a terminal support body (5) wherein the first force-receiving structure (1) and the second force-receiving structure (2) are both located between the carrying end (4) and the terminal support body (5) so as to function as desired by varying force distribution between the first and second force-receiving structures (1),(2) and the terminal support body (5) with the pressure acting on the carrying end (4);
- Therein, the pre-stressed structure (3) is provided between the first force-receiving structure (1) and the limiting structure (11) that is extended from and linked to the second force-receiving structure (2), and forms a structure that generates displacement corresponding to a force it receives;
- It primarily comprises the following components:
- the first force-receiving structure (1):
- being constructed from materials and structures having sufficient supporting capability, and configured to bear a pressure coining from the carrying end (4) through the limiting structure (11) and the pre-stressed structure (3) and acting between the contact structure (7) having lower friction damping of the first force-receiving structure (1) and the terminal support body (5) that contacts the contact structure (7) and is the ground, a structure platform, or a structural plane, meaning that the pre-stressed structure (3) is located between one side of the first force-receiving structure (1) and the limiting structure (11) that is extended from and linked to the second force-receiving structure (2), and the contact structure (7) having lower friction damping is provide at an opposite side of the first force-receiving structure (1) for contacting the terminal support body (5), so as to receive the prestress from the pre-stressed structure (3) and pass the prestress to the terminal support body (5) it contacts;
- wherein the contact structure (7) having lower friction damping of the first force-receiving structure (1) for contacting the terminal support body (5) is constructed from a terminal block (71) having lower friction damping that has sliding capability or a rolling wheel (72) or a rolling ball (73) that has rolling capability;
- the second force-receiving structure (2):
- being constructed from materials and structures having sufficient strength and supporting capability, having one end thereof provided with a contact structure (8) having higher friction damping, and having an opposite end served as a carrying end (4), the second force-receiving structure (2) further having the limiting structure (11) extended therefrom and linked thereto, for allowing the pre-stressed structure (3) to be provided between the limiting structure (11) and the first force-receiving structure (1), so that when a pressure acting between the carrying end (4) and first force-receiving structure (1) varies, the pre-stressed structure (3) generates corresponding displacement;
- the pre-stressed structure (3):
- being provided between the carrying end (4) and the first force-receiving structure (1), being capable of generating displacement corresponding to the pressure it receives, the pre-stressed structure (3) being constructed from a spring device, or a pneumatic device, or a hydraulic device incorporating pneumatic elements, or a magnetic device, and the pre-stressed structure being of one or both of constant and adjustable arrangement;
- and
- the carrying end (4):
- being located at one side of the second force-receiving structure (2), for bearing a load caused by an external force or an object it carries;
- With the aforementioned configuration, the carrier device capable of varying contact damping with pressured displacement has the functions including that:
- when a pressure transferred from the carrying end (4) through the limiting structure (11) to act between the pre-stressed structure (3) together with the first force-receiving structure (1) and the terminal support body (5) is smaller than a set value, the first force-receiving structure (1) has a contact structure (7) having lower friction damping at one end thereof solely contact the terminal support body (5), and at this time a contact structure (8) having higher friction damping between the second force-receiving structure (2) and the terminal support body (5) does not bear the pressure from the carrying end (4), or bears only a part of the pressure that is smaller than or equal to that acting on the contact structure (7) having lower friction damping of the first force-receiving structure (1);
- and
- when a pressure transferred from the carrying end (4) through the limiting structure (11) to act between the pre-stressed structure (3) together with the first force-receiving structure (1) and the terminal support body (5) is greater than the set value, the first force-receiving structure (1) generates corresponding displacement, so that the contact structure (7) having lower friction damping and the contact structure (8) having higher friction damping of the second force-receiving structure (2) jointly contact the terminal support body (5), and at this time the pressure acting between the second force-receiving structure (2) and the terminal support body (5) is greater than or equal to that acting on the first force-receiving structure (1);
- The contact structure (7) having lower friction damping of the first force-receiving structure (1) for contacting the terminal support body (5) is constructed from one or more of the following structures:
- 1) a terminal block (71) having lower friction damping;
- 2) a rolling wheel (72);
- and
- 3) a rolling ball (73);
- The structure of the second force-receiving structure (2) for contacting the terminal support body (5) is a contact structure (8) having higher friction damping constructed from materials and structural geometry that provide higher friction damping;
- Under the same given pressure, the frictional resistance at the contact interface between the contact structure (7) having lower friction damping of the first force-receiving structure (1) and the terminal support body (5) is smaller than that at the contact interface between the contact structure (8) having higher friction damping of the second force-receiving structure (2) and the terminal support body (5);
- The pressure acting between the carrying end (4) and the terminal support body (5) is a sum of its own weight and the load (6) put on the carrying end (4) and/or the pressure the carrying end (4) bears.
