When deciding the specifications of parts to be used in automobiles sold in the market, automobile manufacturers and automobile parts manufacturers carry out tests to manufacture prototype parts, incorporate them into actual vehicles, actually operate the actual vehicles, and collect various data. I have something to do.

The spring design system disclosed in Patent Document 1 includes a spring calculation unit, a spring characteristic database, and a server. The spring calculation unit calculates the spring of the coil spring based on the specification data of the coil spring, and outputs the specification data consisting of the characteristic values of the coil spring obtained as a result. The spring characteristic database determines whether or not the specification data including the obtained characteristic value of the coil spring is appropriate for the required specifications.

The operating element is an element that performs a constant operation by the parts constituting the first vibration isolator or a combination of these parts. Further, the operating element includes a liquid sealed in the first vibration isolator.

Further, the response characteristic is not necessarily limited to one type, and may include a plurality of types of characteristics such as amplitude dependence, attenuation characteristic, speed dependence, and frequency characteristic of the operating element. Here, the data indicating the response characteristics adjusted by the adjusting unit 111 is referred to as response characteristic data.

FIG. 2 is a diagram showing an example of response characteristics adjusted by the vibration isolation device design support device according to the first embodiment of the present invention. For example, as shown in FIG. 2, the adjusting unit 111 sets the set value “a111” for the response characteristic A11 of the predetermined operating element of the first vibration isolator. The set value referred to here means a value that determines the response characteristic A11.

Further, specifically, the adjusting unit 111 uses a servo or an actuator to determine the position of the parts constituting the first vibration isolator or the shape and cross-sectional area of the liquid flow path enclosed in the first vibration isolator. Set these settings by using and adjusting. Further, when the liquid enclosed in the first vibration isolator is an electrorheological fluid, the adjusting unit 111 adjusts the viscosity by applying a voltage to the liquid using an electrode to adjust these set values. To set.

In addition, instead of setting one set value for determining the response characteristic of the operating element of the first vibration isolator, the adjusting unit 111 sets a plurality of set values, or sets a range of set values for determining the response characteristic. Conditions expressed by mathematical formulas may be set.

The acquisition unit 112 acquires vibration data and response data. The vibration data is data indicating vibration input to an operating element when an actual vehicle incorporating the first vibration isolator is used, for example, when an actual vehicle test using the actual vehicle is being carried out.

Get the response data. Further, in the actual vehicle test, when the predetermined operating element of the first vibration isolator shows the response C13 in response to the vibration B13 shown in FIG. 3, the response data showing the value “c113” describing the response C13 is acquired.

That is, the proposal unit 114 proposes a second anti-vibration device having a response characteristic relatively close to that of the first anti-vibration device. In this case, the set value "a121" indicating the response characteristic A11 of the vibration isolator D12 shown in FIG. 5, the value "b121" describing the vibration B11, and the value "c121" describing the response C11 are within predetermined ranges, respectively.

The target response is a condition that the response data of the operating element of the vibration isolator, which is a vibration isolator incorporated in the actual vehicle sold in the market, must be satisfied, and is determined by the specifications of the actual vehicle.

Proposal unit 214 executes the determination necessary to propose the anti-vibration device. For example, the proposal unit 214 determines whether or not there is a vibration isolator capable of responding indicated by the response data acquired by the acquisition unit 212. Specifically, the proposal unit 214 determines whether or not such an anti-vibration device is listed in the catalog. Then, when the proposal unit 214 determines that there is no vibration isolator capable of the response indicated by the response data acquired by the acquisition unit 212, the proposal unit 214 is capable of the response indicated by the response data acquired by the acquisition unit 212. It is determined whether or not the shaking device can be manufactured.

Then, when the proposal unit 214 determines that there is a vibration isolator capable of the response indicated by the response data acquired by the acquisition unit 212, the actual vehicle is based on at least one of the response characteristic data, the vibration data, and the response data.

FIG. 12 is a diagram showing an example of response characteristics, vibration, and response of each of the plurality of vibration isolators according to the second embodiment of the present invention. The anti-vibration device D21, the anti-vibration device D22, the anti-vibration device D23 and the like shown in FIG. 12 are listed in, for example, the catalog of the anti-vibration device. In the anti-vibration device D21, the response characteristic A21 is determined by the set value "a211", the response characteristic A22 is determined by the set value "a212", and the response characteristic A3 is determined by the set value "a213". .. Further, the vibration isolator D21 shows the response C21 described in the response data “c211” when the vibration B21 described in the vibration data “b211” is input to the operating element. Similarly, when the vibration B22 described in the vibration data “b212” is input to the operating element, the vibration isolator D21 indicates the response C22 described in the response data “c212” and is described in the vibration data “b213”. When the vibration B23 to be generated is input to the operating element, the response C23 described in the response data “c213” is shown. The same applies to the vibration isolator D22 and the vibration isolator D23 shown in FIG.

Specifically, in the proposal unit 214, the vibration B21 described by the vibration data “b211” shown in FIG. 10 is input to the virtual vibration isolator, and the response described by the response data “c211” shown in FIG. When the operating element of the virtual anti-vibration device indicates C21, the anti-vibration device D21 showing the same behavior is proposed. That is, the proposal unit 214 proposes an anti-vibration device similar to the virtual anti-vibration device. Similarly, the proposal unit 214 inputs the vibration B22 described by the vibration data “b212” shown in FIG. 10 to the virtual vibration isolator, and receives the response C22 described by the response data “c212” shown in FIG. When the operating elements of the virtual anti-vibration device are shown, the anti-vibration device D21 showing the same behavior is proposed. Further, the proposal unit 214 virtualizes the response C23 described by the response data “c213” shown in FIG. 11 when the vibration B23 described by the vibration data “b213” shown in FIG. 10 is input to the virtual vibration isolator. We propose a vibration isolator D21 that exhibits the same behavior when the operating elements of the vibration isolator are shown. The same applies to the vibration isolator D2 and the vibration isolator D23 shown in FIG.

Alternatively, the proposal unit 214 virtualizes the response C21 described by the vibration data “c211” shown in FIG. 11 when the vibration B21 described by the vibration data “b211” shown in FIG. 10 is input to the virtual vibration isolator. When the operating element of the anti-vibration device is shown, the anti-vibration device D22 showing a behavior close to this is proposed. That is, the proposal unit 214 proposes an anti-vibration device having a response characteristic relatively close to that of the virtual anti-vibration device. In this case, the set value "a221" indicating the response characteristic A21 of the vibration isolator D22 shown in FIG. 12, the value "b221" describing the vibration B21, and the value "c221" describing the response C21 are within predetermined ranges, respectively. The value is close to the set value “a211” shown in FIG. 9, the value “b211” shown in FIG. 10, and the value “c211” shown in FIG. This also applies to the other values shown in FIG.

Alternatively, when the proposal unit 214 determines that it is possible to manufacture a vibration isolator capable of the response indicated by the response data acquired by the acquisition unit 212, the proposal unit 214 can be used as at least one of the response characteristic data, the vibration data, and the response data. We propose a vibration isolation device designed based on this.

In step S215, the proposal unit 214 determines whether or not there is a vibration isolator capable of responding indicated by the response data acquired in step S212. When the proposal unit 214 determines that there is a vibration isolator capable of the response indicated by the response data acquired in step S212 (step S215: YES), the process proceeds to step S216. On the other hand, when the proposal unit 214 determines that there is no vibration isolator capable of the response indicated by the response data acquired in step S212 (step S215: NO), the process proceeds to step S217.

In step S216, the proposal unit 214 proposes a vibration isolator whose response characteristics are pre-designed based on at least one of the response characteristic data, the vibration data, and the response data, and ends the process.

In step S217, the proposal unit 214 determines whether or not it is possible to manufacture a vibration isolator capable of responding as indicated by the response data acquired in step S212. When the proposal unit 214 determines that the vibration isolator capable of the response indicated by the response data acquired in step S212 can be produced (step S217: YES), the process proceeds to step S218. On the other hand, when it is determined that the vibration isolator capable of the response indicated by the response data acquired in step S212 cannot be manufactured (step S217: NO), the proposal unit 214 ends the process.

In step S218, the proposal unit 214 proposes a vibration isolator designed based on at least one of the response characteristic data, the vibration data, and the response data, and ends the process.
